Their membership ;s a manifestation of interest in the scientific phases of the industry by the managements of the respective jompanies. As such, they serve to support the technological progress of the ceramic industry, not only by financial aid, but by the prestige of their names. ..... .. The American Ceramic Society presents to the membership in the following pages a list of the companies *hich are lending support to this work. With each name is given a description of the products or services of the company. Sufficient space was not available to give an adequate listing; just enough is given to classify each company and its products. This should be helpful in answering the question, "What do they make?" The name of the individual who represents the company in Society affairs is also given. This listing should not be considered as an adequate sales description of the products. Company members desiring such publicity are referred to the several trade directories for the industry. Those who supply the ceramic industry and wish to tell a real sales story are referred to the advertising pages of the many trade papers or to The Bulletin of The American Ceramic Society. . It is hoped that this Roster may be revised yearly and that succeeding isshes-will give better coverage of the industry, especially of foreign members.
