Aluminum is a silverwhite metal and is very light in weight (less than three times as dense as water) yet strong. Because aluminum is ductile, it can be drawn into wires or pressed into sheets or foil.
Feldspars Used in manufacture of glass, ceramics and enamels. Includes orthoclase, microcline, and albite (member of the plagioclase series). Gemstones The most valuable total gemstone production is diamond; corundum varieties, ruby and sapphire; beryl varieties emerald, aquamarine, and kunzite.
