To Messrs of the Lead Industries Association!
Attached Is a reprint of a paper presented ty the Associ ation at the annual nesting of the American Ceramic Society in April, 1956, It appeared in full in the American Ceranic Society "Bulletin** of July 15, 1957.
This is a part of our program to encourage greater use of lead in the ceratic industry, which intensified its search for sub stitutes during periods of lead shortages and high prices since the war.
Sincerely youre.
Secretary

Teapofi^ ihofti|H of lend vhkh hireocatfrid ia the past were the result of artificial cootroU and foeerameat stockpiling. It is not likely that each conditions will again prevail becAUM of the la/ge stockpile so* existing and becauso lead reserves of the world are large and axe being increase at a sufficient rate to replace the lead extracted from the groood aneaadly. Detailed statistics to support these conclusions will bo
presented.
