Mosaic gold

Tin IV) sulphide, SnS2- Precipitated from Sn(IV) solution with H2S or Sn plus S under pressure. NH4CI, Sn, S heated gives a yellow solid (mosaic gold). Used as a pigment.

Stannic sulfide may be prepared as a yellow amorphous precipitate by double decomposition of a stannic salt with hydrogen sulfide. The crystalline modification, known as mosaic gold, may be prepared by sulfurizing stannous sulfide in the following way ... 

Talc-like crystalline tin (IV) sulfide is also known as mosaic gold and used technically as a pigment. 

More rarely use is made for the same purpose of other substances such as strontium and calcium chromates, lead oxychloride (Cassel yellow), lead protoxide, arsenic sulphide (orpiment), stannic sulphide (mosaic gold), potassium cobaltinitrite (cobalt yellow), etc. 

Besides powdered metals, certain metallic compounds are sometimes used for the same purposes, e.g., stannic sulphide (mosaic gold), antimony sulphide (iron bronze) and various oxygenated compounds of tungsten (tungsten bronzes). 

Tin(IV) sulfide can be prepared by hydrogen sulfide precipitation of Sn(IV) from solution, to produce a microcrystalline material that is contaminated with oxide. Mosaic gold is a crystalline form of tin(IV) sulfide prepared by high-tempera-ture sublimation procedures. Mosaic gold is the reported product of heating mixtures of (1) tin and sulfur (2) tin, sulfur, and ammonium chloride (3) tin, sulfur, mercury, and ammonium chloride 9 (4) tin(II) oxide, sulfur, and ammonium chloride 9 (5) tin(II) chloride and sulfur 9 (6) tin(II) sulfide, tin(II) chloride, and sulfur.9... 

Stannic sulphide, SnS2, is the higher sulphide of tin, and can be prepared by direct combination of the metal or, still better, of the lower sulphide, SnS, with sulphur. Under ordinary conditions these two substances will not react at a temperature below that which will decompose stannic sulphide. If, however, they are mixed with ammonium chloride the presence of this substance makes possible the combination at a lower temperature. The stannic sulphide formed in this way appears as soft, glistening, yellow crystals. It is used as a bronzing powder, and is known under the name of mosaic gold. In physical properties it is very different from the stannic sulphide which can be precipitated by hydrogen sulphide from a solution of stannic chloride.
