Litbopone shipments declined 3 per cent, indicating decreasing use as a pigment. The distribution of pigments to consumers in 1955 wits essentially the same ns in previous years. The paint industry, continuing ns the principal user of white lend, leaded zinc oxide, and lithoponc, received approximately 78, 115), and 71 percent, respectively, of the total ship ments of these products. 'File paint industry was also the leading consumer of red lead, taking 49 percent of that shipped. Paint pro duction consumed 20 percent of the zinc oxide (lead-free) and 4 per cent of the litharge shipped. Storage-battery makers were the chief users of litharge and the second-ranking user of red lead, receiving til and 41 percent, respectively, of producers' shipments. The rubber industry continued to he the leading consumer of zinc oxide, using 51 percent of total shipments. Manufacture of rubber products also used small quantities of litharge and litbopone. The ceramics indus try, ranking fourth in consumption of load and zinc pigments in 1955, used lb percent of all litharge shipments, G percent of lead-free zinc oxide shipments, 2 percent of red-lead shipments, and 2 percent of white-lead shipments. Titanium pigments continued to furnish the chief competition to lead and zinc pigments in paintmaking. Production and shipments of titanium pigments, based on the titanium dioxide content, estab lished netv records, increasing about 10 and 15 percent, respectively, over the previous highs established in 1954. The use of titanium pigments has about doubled over the past 11 years, displacing lead and zinc pigments, especially while lead and litbopone, in many paint formulations. r -*r`1 '; ' 1 Ll1hop one r / A 1 / / / /y \ /l // / )\ .\'\\V/////1<// / \/ i \/ V \ Zme \ oxide \L-ea-d-ed jinc oxide i i i i 1- l-l--L- l l l l t A1 11 Vi A Lu \v\ // /M i l\ ^V _ 1 ft \i \ \ .. t ______ : K /\ ! r- A '' * \/ V\ \ \ j j -2 -1 1.1 1 - . . . ii - i - i i . 1 1 -1--L- Figure 2.-- Trends in shipm ents of zinc pigments, 1910-55.
