Lead crystal with added nickel acquires purplish color. Nickel together with a small amount of cobalt was used for decolorizing of lead glass. Chromium is a very powerful colorizing agent, yielding dark green [6] or in higher concentrations even black color. Together with tin oxide and arsenic it yields emerald green glass.
A tintype, also known as a melanotype or ferrotype, is a photograph made by creating a direct positive on a thin sheet of metal, colloquially called 'tin' (though not actually tin-coated), coated with a dark lacquer or enamel and used as the support for the photographic emulsion. It was introduced in 1853 by Adolphe Alexandre Martin in Paris. [1]
Lead-tin yellow was sometimes called massicot, although it is a different substance. [3] Prior to the development of modern analytical tools allowing for microscopic testing of paint, it was not always possible for art historians to distinguish between similar pigments, meaning that most yellow pigment containing lead was generally labeled ...

In its lattice structure, zinc and iron atoms share the same lattice sites. Kesterite is the Zn-rich variety whereas the Zn-poor form is called ferrokesterite or stannite. Owing to their similarity, kesterite is sometimes called isostannite. [5] The synthetic form of kesterite is abbreviated as CZTS (from copper zinc tin
