Last year It vss decided to oooentrate oar promotional efforts on behalf of lead plgaents on thoao need 1b etel protective paints and oo yellow traffic Boridrg paints. It was further decided to concentrate on the specifier* and ultlnete users of these paints rather than ea paint nanufacturers who are veil oovered by oar ovn aaifcer* who aalce plgaents. It vaa also decided to Investigate farther the usee and arlcet possibilities of Bolybdate oracle (a lead aolybdate-laad chroaste pigment) which has been gracing steadily. Tbeee three groups of lead pdg snts near aooooat for an annual lead oonso^tlon of ease 1*0,000 tone and are all growing. Had lead la still (tairally oooaldared the standard for prising stnwtoral steel. While its use has fluctuated vlthla narros Halt* Is reoast years, based on fire eooth fifurea It ahoold ttuM a nodest Increase this year to the highest level since 1957. To this net be added the lead seed to anka such never pigaenta as basic lead silicate, basic lead silica ohroaete, trl-bealo lead phoapbo sillcats, and a nail proportion cf basic lead ohroaate, lead olybdate and basic lead carbonate, had lead la used only for prising and Intamediate coats while sort of the others are althar used for top coats or for all coats. Wban all cf these are added to the fairly stable oooawqs'tlcn cf red lead, It 1s obvious that ths use of lead for eetal protective paints la growing, although no separate statistics are available on tho never pigsasts. Principal eoagetltloo for prlaare cones fros Iron azide, olno rich paints and sine ohroivtte and for top coats free eluwinlus and tltsnisn paints. This year our promotion has cooslatsd of foar one-page two oolor ade In Engineering Vevs-Aecard and two one-page two color ade each In laarlcan City and Urban and Rural Roads. We have continued to distribute on request Plgmnts Technical Letter Vo. 15, a co^Uatlon of paint fomolaa for natal i protection under a variety of conditions, first printed several years ago. We also distributed to 6,000 corrosion engineers, paint technologists and executive reprints of an exoallant trade paper article on the history cf painting tho Sea francisco-Oaklsnd Bay Bridge with lead paints. Wa believe that this progrus Hioald be continued along prsooBt llaso sad Perhaps Intensified soaswhet.

Host of the growth, therefore, Is attributed to expansion at tha use at yellow for truffle Barking paint, which la eatiaated to he tha largeet single use cf lead ohroaate, using about half of tho nearly 0,000 a teas of laad going Into all laad cfcrosata. ; v ';<iyv N 3350.01 To dot* load chroewte had no oeapotltion la uling tha yellow paint and yellow baa been replacing iddta (contains no laid) for *0.-7 pcrpcaea. tar effort* #o far have bean to aooooraga vldw ua of yallow for sort pcpcoea. fteoest raaaarch sponsored by th# Bolphur laatltut# baa dovalopsd specially applied aulphur, ita yellow color strengthened by addition of a dya, Bans* yellow, for traffic narking.
