Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable
Tin(IV) iodide, also known as stannic iodide, is the chemical compound with the formula SnI 4. This tetrahedral molecule crystallizes as a bright orange solid that dissolves readily in nonpolar solvents such as benzene .
Tin(II) iodide, also known as stannous iodide, is an ionic tin salt of iodine with the formula SnI 2. It has a formula weight of 372.519 g/mol. It is a red to red-orange solid. Its melting point is 320 °C, and its boiling point is 714 °C. [1] Tin(II) iodide can be synthesised by heating metallic tin with iodine in 2 M hydrochloric acid. [2 ...
Historically the stibnite form was used as a grey pigment in paintings produced in the 16th century. [6] In 1817, the dye and fabric chemist, John Mercer discovered the non-stoichiometric compound Antimony Orange (approximate formula Sb 2 S 3 ·Sb 2 O 3), the first good orange pigment available for cotton fabric printing.

The color is caused by the size and dispersion of gold particles. Ruby gold glass is usually made of lead glass with added tin. Silver compounds such as silver nitrate and silver halides can produce a range of colors from orange-red to yellow. The way the glass is heated and cooled can significantly affect the colors produced by these compounds.
