GENERAL SUMMARY
The outstanding feature of the lead industry in 1944 was the
decrease in new supplies, which failed to balance a high level of con
sumption. Production from domestic mines, which is the principalij
source of now supply, continued to decline, largely owing to a severe|
shortage of manpower. Imports of refined lead--a ready source of]
immediately usable metal--were lower, consumption was maintained I
at a high level, and Government stocks of refined lead were steadily]
reduced to a point considered below the margin of safety. At the]
end of the year a sweeping revision of existing General Preference]
Order M-38 was announced by the War Production Board to restrict]
consumption further and thereby help to ease a situation that had]
grown critical. The end of the European phase of the war in May]
1945 was accompanied by signs of gradually diminishing military j]
requirements, but the bacldog of civilian needs for lead during the|
period of partial reconversion will maintain demand at a high level.!
The prospect for 1945 is one of the continuing insufficient supply fori
all potential consumers but of adequate supply for military and!
essential civilian requirements.
la
Refined primary lead production from domestic and foreign ores!
and foreign base bullion decreased 1 percent in 1944, the total being!
only 4,849 short tons less than the 1943 output. Year-end stocks at]
domestic refineries (physical inventory) were less than half the total!
at the beginning, and consumers' inventories were 22 percent lower'd
Total imports of lead in all forms during 1944 showed a gain of lestl
than 1 percent. An increase in receipts of lead in ore, concentrates*
and matte--largely from Newfoundland and Australia--offset (1
decline in imports of refined lead, the principal source of which wsffi
Mexico. A substantial amount of reclaimed lead and lead scrap from
Australia partly balanced theabsence of base bullion from thaH
country.
l9
The established price of 6.50 cents a pound for lead at New Yon
remained unchanged throughout 1944.

WAR AGENCY REGULATIONS
Lead remained under Government control throughout 1944, under
War Production Board General Preference Older M~38, which pro vides for the regulation of shipments, deliveries, and a reserve pool for
allocation. In actual practice the control of lead was confined to the
allocation of Government-owned stocks of foreign lead and to prohibi
tion of the use of lead for certain purposes; all essential uses were free
from control, subject, of course, to limitations imposed by virtue <r
regulations on the use of other materials needed for the manufacture
of lead-containing products. As a result of a decrease m new supplies,
Government stocks of refined lead were steadily reduced. I o help
ease the resultant critical supply position the War Production Board
amended Order M-38, effective December 2G, to restrict most civilian
uses of lead to an annual rate of GO percent of the 1944 level of con
sumption. Under the revised order, restrictions and availability of
lcfwl were defined under Uirco listings; A, prohibited uses, 1$, cud uses
for storage batteries, cable covering, tetraethyl, ami ammunition for
military use only (for which lead was made available, 100 percent)
and for solders, bearing metals, brass and bronze for which the use of
lead was unrestricted; and C, the greater portion of civilian uses with
the restriction mentioned above. Greater restrictions were placed
on oilier than essential uses by an amendment to the order on Janu- ,
ary ]5, 1945, followed by the prohibition of certain end uses m the .
order by another amendment on February I. Because the lead
supply became increasingly critical, permissible uses of the metal
were again curtailed, in an amendment to the order on March 31,
to include only end products. A list of 04 permissible uses was sub- I
stituted for the previous lists A, B, and C which covered -restricted ,
uses, unrestricted uses, and quota percentage restrictions
To conserve further the foreign supply of lead available to the
United States for war purposes, War Production Board General im- <
ports Order M-63--governing imports of strategic materials--was
amended, effective February 14, to place collapsible lead tubes, stor-j
ago batteries, and lead foil under import control. Later, in April,,
another amendment included lead disks, slugs, and other scmifabri-s
eatod forms manufactured in whole or in part from lead or lead alloy.
Limitation Order L-180, affecting storage batteries, was amended
in April 1945, to insure that the lead shortage was not reflected in theJ
quality of replacement storage batteries produced in 1945 und toj
prevent the sale of batteries except under conditions in which replace-!
menl was imperative.

The Premium Price Plan for ovorceiling payment for production!
of lead in excess of quotas was maintained throughout 1944. A briefa

RECIPROCAL TRADE AGREEMENTS
|
Marked opposition was voiced early in 1945 against certain prt8
posals embodied in a bill (D. R. 2652) placed before Congress t| extend the Reciprocal Trade Agreements Act. The lead industiy &fl a whole opposed the proposed delegation of power to the Presided to make a further cut of 50 percent in the rates of duty pievaillM

As finally written and passed by the Sen bill extends the act for 3 years and allows for as reduction in the rates of duty prevailing on Jan porary reduction under wartime agreements rema ever, and any cut in the duty will oe with respec lished by the 1930 tariff act. Under the "tn policy, any reduction embodied in a reciproca apply equally to virtually all countries.
POSTWAR OUTLOOK
The outlook for lead for the few years followin upon the interrelated factors of production, impo sumption, and price. These in turn depend to a end of the war in the Pacific and how soon the ductive capacity as a whole--can be directed to under competitive conditions.
Production.--Mine production during the wa reach the peacetime 1925-29 average of 664,230 t tion of ore reserves in certain districts and to a manpower.

Co mines could fill the demand for new lead for a adequate price and tariff protection, but the past on foreign lead is expected to continue to an incre resources are drained further.

Assuming that some tariff pro tection will remain in force, the factors of demand by consumers and higher production cost to smelters and refiners will tend to keep the price on a plane relative to an expected generally higher-cost level for all commodities.

DOMESTIC PRODUCTION
Pig lead is produced at primary plants that treat ore, base bullion) and small quantities of scrap and at secondary plants that process scrap exclusively. Both types of plants may make refined lead or antimonial lead. Because of the large quantity of hard lead--such as battery scrap--melted at secondary smelters, the output from this type of operation is essentially antiinonial lead alloys, rigures for the production of refined lead and alloys at secondary plants are given in the section on Secondary Uead. The 17 smelters and tenners in (he United States canvassed in 1944 (including one smaller smelts which reported for the first time) consumed 477,765 short tons (lecontent) of ore, only 15 percent of which originated m foreign countries
REFINED LEAD
Despite the continuing labor shortage, the 10 primary refineries the United States were able to produce 476,131 tons of refined le 1 percent above the 1943 output of 471,475 tons.

SECONDARY LEAD
Although some scrap lead is treated at primary smelters and^
refineries, the greater part is received at a large number of plants' that treat secondary materials exclusively. Secondary lead is recovered in the form of refined lead, antnnomal lend, and other alloys.
Recovery at primary and other plants' in 1943 and 1944 is shown in the following tabic. Secondary lead recovered :n 1944 was .'{ percent loss than in 1943 and was equivalent to 71 percent of the total refined primary lead produced in the United States, further details appear

Government stocks.--111 addition to industry-owned stocks, 11 sizable l luiugh diminishing supply of Government-owned lead was held at various depots throughout the United Slates for release through alloe.alion lo consumers as needed. According to reports submitted to the* Tin-Lead-Zinc Division of the War Production Board, Government Flocks totaled 90,454 tons of refined lead on December 31, 1944, com pared with 173,875 tons of refined lead on January 1,1944,
DOMESTIC CONSUMPTION
A survey of 570 plants in 1944 (530 (corrected figure) in 1943) repre senting an estimated 90 percent of the consumers of refined lead showed ft total consumption of 722,820 short tons of refined lead, a gain of 7 percent over 1943. Some secondary as well as primary refined lead is included in this figure. Antimonial lead, unrefined scrap lead, and lead in alloys are excluded. The additional number of plants cov ered in the 1944 survey include for the most part small consumers that did not report in previous years. The lead consumed by these plants was small in relation to the total and does not measurably affect the
I rends indicated by comparison with the 1943 data. Of the total consumed, 22 percent was used to make red lead and ,
litharge, 15 percent for cable covering, 11 percent for tetraethyl 10
percent for storage batteries, 4 percent for sheet lead, 4 percent for ammunition, and the remaining 34 percent for a variety of products

The two major markets for lead in the Unite and St. Louis; much of the lead produced in prices normally based upon quotations in thes , pension of the London Metal Exchange dealings London market has had no direct influence on . and the differential between St. Louis and ^remained at 0.15 cent a pound, an amount app ..charges between the two points.
$ " The ceiling price for common lead---6.35 cen . and 6.50 cents, New York--remained unchan . hor companson it is of interest to note that the
by the primary producers for all grades of r ltunoniol lead) sold in 1944 was 6.4 cents a po
same as in 1943. The 1944 price of 8.0 cents f n the separate State chapters, represents the a nee received for refined lead plus the increme er pound based upon the total domestic mine ead---of $13,745,815 in overquota premiums
acts paid by the Metals Reserve Company.
168 MINERALS YEARBOOK, 1944
The Premium Price Plan, whereby producers (miners) of lead (copper and zinc were also included in the plan) receive increments above the ceiling price (through Metals Reserve Company) for over quota production, was maintained throughout 1944. As the plan is operative only until July 31, 1945, Congress passed the HaydenMcFarland bill, S. 502, on June 14, 1945, to extend the time limit to June 30, 1946. More complete details of the scope of the Premium Price Plan--which was effective February 1, 1942--can be found in the chapter on Lead in Minerals Yearbooks for 1942 and 1943. In May 1945 the Office of Price Administration released a comprehensive compilation of data showing production of copper, lead, and zinc under the Premium Price Plan since February 1942, at the various quota levels and the payments made. The salient statistics from this report, with reference to lead, are given in the following tabic.

WORLD ASPECTS OF THE LEAD INDUSTRY
The rapid succession of events in 1944 and early 1945, culminate in the unconditional surrender of Germany in May 1945, opened th3 door to revealing greater detail regarding the lead industry in foreign countries than had been available since 1939. Censorship restriction^ ---imposed for reasons of security--have been removed by the govern! ments of most of the lead-producing countries, and unrestricted information regarding European countries formerly under Axis control is beginning to flow by way of official channels. Neverthe less, it is not yet possible to present a complete picture of world pro duction and consumption of lead during the years of the Europcai phase of the war. The lead position of the United Nations wa satisfactory in 1944, and, although consumption probably did gain, somewhat, this increase was accomplished at the expense of accumujj lated stocks owing to an indicated over-all decline in production.

QENERAL SUMMARY
Further improvement in sales of lead and zinc pigments was evident! in 1944 over the generally low performance of this group in 19421 Conditions that applied to the earlier war years continued in 19441 In large part these conditions included outstanding war requirements for many items and shortages of essential crude materials and ofl manpower. For several years sales of the various pigments have non indicated actual demands for any of the items, because all the pigment| have been influenced by manpower shortages and all have been affected in varying degree by shortages of necessary primary anffl subsidiary crude materials. The crude materials used for certain pigments have been in more abundant supply than for others; as.,s result, during the war some pigments have benefited--temporarily h least--at the expense of others. In 1944 war needs took a prepondefl ant share of total sales of pigments, with the proportion mcreosiifl over the earlier war years. Pigments manufacturers continued to bi hampered by restrictions on supplies of linseed and other drying oul and of slab zinc, and by limitations on containers. At the end of tK| year consumers of lead for the manufacture of pigments for civilian requirements faced sharp cuts in the quantities of this metal thn could he used. Late in 1944 it was announced that, effective Jaffl nary I, 1945, the quantities of fats and oils for use in the manufactaj of protective coatings, coated fabrics, and floor coverings for civiliw
consumption were to be reduced from 70 to GO percent of the averM| quantities for 1940 and 1941. For over a year, producers had beH trying to build their civilian accounts as a safeguard against prospja tive cancellation of war orders, but these efforts did not comeaB fruition in 1944. Late in the year supplies of paint, varnish, ul lacquer materials were bolstered by limited releases of surplus stein

it is possible to ascertain, sales of zinc sulfate for agricultural purposeal
were also at a new record rate in 1944. For the most part, sales of;i
pigments for the manufacture of ceramics rebounded somewhat from.]
the low rates that prevailed in 1942 and 1943, but white lead did notj
share in the gains. Use of zinc oxide in the manufacture of rubber!
receded in 1944 from the relatively favorable rate that prevailed inis
1943; distribution of litharge for this purpose, which had been gaining?

MINERALS YEARBOOK, 1944
In the first place, we have no reconversion problems. With reasonably speedy
victory over Germany already assured and with victory over Japan in much,
clearer prospect than seemed likely before Germany's impending collapse, we are!
fully equipped for a head start without necessity of awaiting the final victory in]
the Pacific theater of war, while many other industries will have to reconvert!
their factory operations and cannot get started in new production for a consider-!
able time to come. However, no matter what other industries do, they will need!
our products for practically any activities in which they engage.
.1
As civilian production gains headway in catching up witli the great backlog of!
deferred civilian needs, the demands upon the paint industry may be expected toj
Surpass the records achieved in the peak war years.
.
The expected gain in postwar production of automobiles untill
pent-up requirements arc filled was outlined in the report of this! series for 1943. This gain and increases in production of other! civilian equipment retarded by the war will call for pigments fori finishes, storage batteries, rubber, and other items that are large! pigment users. Railroads will need large supplies of pigments, asl pointed out by Trigg in the article already cited, to rehabilitate rolling!
stock, stations, bridges, and other properties and equipment. He!
indicated also that a large merchant marine and the biggest Navy in^
the world will provide a largo postwar market for pigments. The^
pigments export market for the purposes itemized could provide &J
postwar outlet for very large tonnages.
.
There seems to be little question regarding the size of postwar r&
quirements for pigments. The main question concerns the proporj
tions of the market that different pigments will supply. In this coni
nection, the prewar shifts from certain pigments to others are expecteij
to continue in postwar years.
PRODUCTION
Previous reports of this scries have indicated that sales are a better!
guide to activity in the pigments industry than production because!
completo data are not available on stocks and materials classified asl
production of one item are sometimes disposed of under another!
classification. Moreover, pigments produced under one classification!
at a plant aro sometimes employed at, a plant, of another company foij
blending into another pigment in the lead and zinc group. Th^
Bureau of Mines attempts to eliminate all possible duplication and i
tabulate products only in the form in which they enter final use fi
pigments. Thus the quantities of basic lead sulfate and zinc oxid|
that are blended to make leaded zinc oxide are omitted, except ai
leaded zinc oxide. Duplication caused by other blending, which is
on a considerably smaller scale, is also avoided insofar as possible
Pigments consumed by the producing companies, however, to makl
products beyond those covered by this report--that is, paint, stora
batteries, and other articles--are considered as sales.
The value of lead and zinc pigments in 1944 totaled $85,889,00
a gain of 10 percent over 1943; it was the largest since 1929 and ei
ceeded 1941 by a narrow margin.
'

Figures covering zinc chloride for 1944 are not available because? of the refusal of one company, believed to be large, to give reliable
data. Sales of zinc sulfate failed by 11 percent to equal the rate for 1941J
but except for that year they were the highest on record.
CONSUMPTION BY INDUSTRIES
i WHITE LEAD
Sales of this pigment, which declined in 1943, returned virtualW
to the 1942 level in 1944. Total sales for the dry and "in oil" varietia
increased 13 percent in 1944, but amounted to only 84 percent of th|
annual average for the prewar 5-year period, 1935-39; they were noj
much more than half of the average for the period of high industna
activity in 1925-29. The dry class gained 18 percent compared will
7 for the "in oil" grade, and it has fared much better, on the wholi
for many years.
.11
By far the largest part of white lead sales is for consumption in tU
manufacture of paints, ordinarily over 90 percent entering this u m
93 percent was reported as having gone into paints in 1944. Iti
believed that a break-down of the Other class would raise the pain
total. Sales of white lead for the manufacture of ceramics declinl

LITHARGE
A new peak rate of sales of litharge for storage-battery manufactu in 1944 carried total sales of litharge to record heights; they were! percent higher than in 1943 and 13 percent above the previous pe in 1941, and they thus made the best showing of the pigments cover^j by this report. Battery manufacture took more than half of the tot a condition that has existed only once before, in 1932, since the Bure of Mines began to collect data on distribution of sales; in 1932 tojjj sales of litharge were only 80 percent of the amount sold for bath manufacture in 1944. In addition to the litharge used to ma batteries, the storage-battery manufacturers themselves produce] black or suboxide of lead which they use as a substitute for lithari The amount so used in 1944--01,000 Lons--equaled the record tom for 1941 and was 1,000 tons above 1943. In 1944, 58,000 tontijj pig lead were required to manufacture the suboxide, compared 57,000 in 1943. Black oxide figures arc not included in the Burl of Mines totals for litharge. Insecticidal use of litharge also ml a new high record for the second successive year in 1944, surpaa the previous peak of 1943 by 28 percent. Ceramics took 25 perl more litharge than in 1943. Other of the larger users of lithffl except oil refining, took less of the pigment in 1944 than in la the decline for rubber contrasting with the uptrend of recent yef The drop in use in chrome chemicals is explained more by restrift allowances of chrome than of lead.
Production of litharge amounted to 146,900 tons in 1944 compl with 112,037 tons in 1943.

LITHOPONE
The lithopone statistic? in this report are given on the basis ol ordinary litliopone sold as such plus the ordinary lithopone conteni of the high-strength product. This method of publication is used conceal the operations of one company wliich always dominates thi output of the high-strength product and is the only producer in somj years. In 1944 three companies, operating four plants, produce< high-strength lithopone, but one company made a negligible contribu: tion to the total. Lithopone sales in 1944 were influenced by thi historic peak in total sales of all paint, varnish, and lacquer materials]] over three-quartern of the sales of this product regularly going into] paint, varnish, and lacquer channels. It is significant that lithopone sales for paints rose somewhat less than total sales of paints, varnish, and lacquer materials, inasmuch as lithopone would naturally benefit from restrictions on sales of other pigments, such as zinc oxide an< titanium dioxide. Floor coverings and textiles take the next-mos1 important amounts of lithopone, and sales for this purpose dropp 8 percent in 1944. A separation of the quantities for 1944, baseef oj somewhat incomplete data, indicate that 9,578 tons were for floqi coverings and 5,168 for coated fabrics and textiles. Use of lithoponl for the manufacture of paper lias been gaining and amounted to 6,48' tons in 1944, compared with 4,043 tons in 1943, 3,423 in 1942, an! 5,559inl941. The 1944 total is a peak rate since 1937, the first year foil which separate figures for this use are available. The consumption of titanium dioxide for paper manufacture was also at a high rate iig 1944, the gross weight of titanium pigments showing a peak rate sine before 1935 (the first year for which separation is available) but th| Ti02 content lagging behind that for 1943 and the even higher total ft: 1941. Printing ink took a large amount of lithopone (1,216 tons) ! relation to most other years since before 1936 (the period for whid data are available); the total for 1941 (2,301 tons), however, w| considerably above all other years since before 1936. Exports f included mainly under Other, but one company at least classifies pa of its exports according to the end use.
Plant capacity for the production of lithopone was reported to to 155,000 tons in 1944 or relatively the same as the 157,000 tons for 1948
Production of lithopone totaled 133,960 tons compared with 132,6ST tons in 1943. Stocks were reduced in both years. The plant of t

RAW MATERIALS USED IN MANUFACTURE OF LEAD AND ZIHj PIGMENTS AND ZINC SALTS
Figures covering the raw materials used in making pigments

prepared. Data for 1943 are given below, and those for 1944.
appear in a subsequent report.
._
Lead pigments and zinc pigments and salts are manufactured froj
a variety of materials, including ore, refined metal, and such seconds
materials as scrap and waste from various industrial processes. *f
1943, 93 percent of the lead in pigments was derived from pig 16
and 7 percent from ore. Of the lead in ore used to make leaded
oxide, about 10 percent was from foreign sources. The proportjg
for zinc pigments in 1943 was 78 percent from ore, 8 percent from su
zinc, and 14 percent from secondary materials; about 14 percentj
the ore used was foreign.

zinc pigments and zinc salts are given in the tables in the first part of;
this report. For most of the products covered there was little change'
in average prices received, but those for both red lead and litharge
declined. The lower values for these two products can be explained),
only by variation in delivery points of portions of the total sales.'
Producers' values are reported on an f. o. b. plant basis. The ceilingi
prices established by the Office of Price Administration for the pig

FOREIGN TRADE *
The average annual value of foreign trade in lead and zinc pi
ments has remained relatively high during the war as compared wit prewar levels. The principal trade is under the export classifications no import item reaching $30,000 in value in cither 1943 or 194* Lead pigments export values declined 4 percent in 1944 as compar~
with 1943 but were 142 percent above the average for the 5-year p
riod 1935-39, whereas zinc export values declined 26 percent and w
275 percent above the prewar average. Total exports of both class,
(lead and zinc pigments) in 1944, however, amounted to only 4 perc ' of the value of total production in the United States.
Figures on imports and exports compiled by M. B. Price, of the Bureau of Mines, from records of

Exports were smaller in 1944 by 33 and 8 percent,] respectively, and the virtually constant rates for 1943 and 1942 were] below those for 1941. Principal zinc salts exported, shown separately on an annual basis for the first time in 1942, are zinc sulfate and zind] chloride.

Exports,--Almost the entire quantity of titanium concentrates and_
alloys exported in 1944 went to Canada. Mexico received 90 percent!
of the pigment exports; Cuba, 3 percent; Brazil, 2 percent; and others
countries, 5 percent. Exports of tetrachloride dropped from 694'.|
short tons in 1943 to 372 tons in 1944; 57 percent went to United.
Kingdom, 30 percent to Australia, and 13 percent to Canada. The
total exports of titanium products (including coventrates) in 1944
were valued at 2% million dollars.

STOCKS
Although inventories of ilmenite at the end of 1944 were about
one-fourtn larger than a year earlier in terms of TiOa content, they?
represented only about 5 months' supply at the 1944 consumption
rate. Stocks of rutile increased about 12 percent by the year end and
were probably more than 6 months' needs in view of the declining
welding-rod output.

CONSUMPTION AND USES
The 19-percent increase in use of ilmenite in 1944 over that of the! preceding year may be ascribed to the unsatisfied demand for titaniumj pigments. Consumption for pigments was 97 percent of. the totalj most of the remainder going into alloys and cemented carbides. Thff

Titanium, alloys.--The titanium ferro-alloys are important additiyaffl
'in the production of rimming and killed steels. Tho titaniumTM
treated steels are cleaner, give higher ingot yield, and have generally*
better physical characteristics than untreated steels and some of9
those treated with other deoxidizers. In these applications there isn
little or no titanium residual in the finished steel. Titanium is alscij
used as an alloying element, especially hi stainless steels where itsS
..main effect is through carbide control to inhibit intergranular corrosion*
and embrittlement. A titanium alloy steel, now in commercial!
production, has made possible the direct application of white or!
light pastel vitreous enamels to steel without tho use of a ground-coatl
enamel. This one-coat enameling steel possesses exceptional cold-3
drawing characteristics and resistance to sagging or bending at enamel!
firing temperatures and is reported not to age-strain.8 8
'8
Other uses.--Titanium tetrachloride was used as a screening smoke!
during the First World War and has been employed in substantial!
volume during the present conflict. At first it was usually prepared!
by chlorinating rutile in the presence of carbonaceous material?!
Subsequently and during the current war, titanium cyanonitride--<-3
an electric-furnace product--was reacted with chlorine to make the!
tetrachloride. These were high-temperature processes requiring care-|
ful controls, and the product was likely to bo contaminated with|
impurities contained in the raw materials. Later, better results were|
obtained by substituting pigment titanium dioxide briquetted with*
finely ground charcoal and a binder in place of the cyanonitride. |
PRICES
f]
No price changes affected any form of titanium in 1944. IlmenitejS
and rutile prices were fixed by the Office of Price Administration! February 22, 1943 (Regulation 327), at levels prevailing in March,]
1942. Ilmenite, 60 percent Ti02, was nominally quoted St $28--$30 a long ton, f. o. b. Atlantic seaboard, and rutile, 94 percent TiOj, at 8-10 cents a pound. Steel quoted ferrotitanium, ton lots, at $1.23
per pound of contained Ti for 40- to 45-percent grade and $1.35 for-
20- to 25-percent grade; and fcrrocarbontitanium, 15-20 percent Ti, at $142.50 a short ton for 6- to 8-percent, carbon and $157.50 for-i
3- to 5-percent carbon. Titanium metal, 96-98 percent, was listedr' at $5-$5.60 a pound. The base price of manufactured titanium] dioxide remained fixed at 14K-16K cents a pound.
