UNUSUAL STRENGTHS are among the numerous advantages obtained in Columbia's new thermosetting plastic, Allymer. Other points of superiority are its resistance to heat, crazing and mar ring . . . form stability . . . resistance to weather and t o solvents, as proved in various critical war materials. Allymer is now available in sample quantities for experimental purposes.

This remarkable packaging achievement of the Glass Container Industry focuses attention on its splendid wartime record. Among t h e many products destined for export i n glass to our fighting men overseas, 1944 requirements call for 678,800,000 beer bottles . . . 50,000,000 bottles for water purifier tablets . . . 98,600,000 insect repellent bottles!

When it can't be left to chance Alone on t h e o c e a n s floor, t h e N a v y diver works w i t h care and precision. Hampered by his cumbersome equipment, beset w i t h innumerable other difficulties, he m u s t nevertheless perform skilled mechanical operations for essential construction. His work must be right . . . nothing can be left t o chance. N o r can chances be taken in the production of Columbia chemicals . . . for so many products are dependent for their standards and efficiency on chemicals which conform in every w a y t o specifications. Columbia is meticulous in its production methods, its tests and inspections. In leaving nothing t o chance in its o w n processes, it eliminates risks for its customers. T h i s is w h y Columbia is t h e exclusive source of supply for so many.

PIG IRON production gets a big boost when high sulphur content can be reduced. Soda Ash has t h e stuff, chemically, t o do it—but the problem is to bring it into sufficient surface contact with the molten iron. Columbia solves it with i t s Soda Briquettes—compressed pellets composed chiefly of Soda Ash. Added t o the ladle at the time the pigs are cast, Soda Briquettes get t h e surface contact necessary for effective desulphurizing—and reduce expensive dusting losses. A newly prepared folder will be furnished on request.
SODA ASH production records illustratethe tremendous Twentieth Century growth o f the nation's chemical industry. A basic chemical for the Glass industry, Soda Ash is also used extensively by the Textile and Paper industries and serves in a wide variety of cleansing operations. In a single month, total U.S. production of Soda Ash now approximates that for the entire year of 1899... and Columbia's own annual production exceeds that ton nage by a substantial margin.
