Could this mean a
FORTUNE to you?
Every pound of bauxite, the ore from which aluminum is produced, contains a minute quantity of gallium. While no commercial method has been developed to extract all of this metal, Aluminum Company of America is now removing a small fraction of the gallium present in Alcoa bauxite, and is offering commercial quantities of it in high-purity metallic form. Gallium presents properties that are indeed stimulating to scientists, researchers and development engineers—properties that open the door

to possibilities in numerous fields. Gallium has an unusually wide liquid range. Although it melts at body temperature, it will not boil until heated to about 3600° F . I t "wets" the surface of many materials—can be painted on glass to make a brilliant mirror. And it expands when it solidifies. We can't predict what the future holds for gallium, but we're betting there *vill be some amazing-—and profitable—developments in t h e years to come. It may pay you to investigate this wonder metal.
