Powdered aluminum is used to create silvery metallic and interference effects.
Aluminum powder is lightfast, but it must be protected from oxidation. Under normal conditions, aluminum metal is protected by a thin layer of oxides that forms on the metallic surface.
Aluminum is an abundant element, but it occurs naturally in non-toxic forms as a mineral oxide, not as a metal. Aluminum metallic powder is considered safe when it is suspended in an acrylic binder, for use in specialty artist and craft paints. Aluminum m
Although aluminum is an abundant element in the Earth's crust, it was a semi-precious metal until the late 19th century, when an electrolytic process was developed for extracting aluminum from the mineral oxide forms in which it naturally occurs.
