2. Chemical coloring of metals - Wikipedia

   en.wikipedia.org/wiki/Chemical_coloring_of_metals

   The processes of chemical coloring of metals are as old as metalworking technology. Some of the earliest-known examples of colored metal objects are about 5,000 years old. They are bronze casts with some silver-colored parts, which originate from the Anatolian region. [2] Similar processes can be found on some ancient Egyptian copper sheets. [3]

3. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   Microscopic close-up of mild steel sheet metal. Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is ...

7. Alumina effect pigment - Wikipedia

   en.wikipedia.org/wiki/Alumina_effect_pigment

   The coating of the alumina platelets with high-refractive metal oxides, such as with titanium dioxide and iron(III) oxide leads to strongly reflecting effect pigments. These pigments possess a strong glitter effect. The coating process is analogous to that used for metal oxide mica pigments except it starts from an aqueous suspension of Al 2 O ...
