Tin liquor, Tin mordant (Dyeing), stannous chloride, used as a mordant in dyeing and calico printing.
It is very soluble, but in dilute solutions it readily forms a basic salt, so stannous chloride is usually used in very concentrated solutions.

A trace of stannous chloride (protochloride of tin) turns the red solution purple: excess bleaches it.
Stannous chloride (protochloride of tin) gives a brown deposit of metallic arsenic.
The constitution of methyl orange follows from the fact that on reduction by stannous chloride in hydrochloric acid solution it yields sulphanilic acid and para-aminodimethyl aniline.
Its constitution is determined by the facts that it may be prepared by reducing nitro-azo-benzene by ammonium sulphide and that by reduction with stannous chloride it yields aniline and meta-phenylene diamine.
These two bodies were first identified by Drechsel[184] and his co-workers as products of the decomposition of various proteids, when the latter are boiled with hydrochloric acid and stannous chloride.
In the reduction by stannous chloride the solution of the ore in the flask is heated to boiling, and a strong solution of stannous chloride is added until the solution is completely decolorized; then 60 cc.
Stannous chlorid and potassium carbonate are added to ginger cake to give the same color to the product made of molasses and a poor grade of flour as that made from good flour and honey.
Alumina separates the cadmic oxide from the bismuthic oxide, the stannous oxide from the stannic oxide, and the stannous oxide from the antimonic acid.
H2O, is obtained by passing sulphuretted hydrogen into a solution of bismuth nitrate and stannous chloride.
Bismuth dioxide, BiO or Bi2O2, is said to be formed by the limited oxidation of the metal, and as a brown precipitate by adding mixed solutions of bismuth and stannous chlorides to a solution of caustic potash.

Stannous Chloride, in a little lime water and add, together with 1/2 oz.
Bright and fast orange yellows are got by mordanting with 8 per cent stannous chloride instead of alum.
Rocelline affords the same reactions as artificial ponceau, but if steeped in a concentrated solution of stannous chloride it is in time completely discharged, which is not the case with artificial ponceau.
Moreover, it is turned greenish bystannous chloride.
The ease with which stannous chloride takes up chlorine to form stannic chloride makes it a good reducing agent in many reactions, changing the higher chlorides of metals to lower ones.
Stannous chloride is prepared by dissolving tin in concentrated hydrochloric acid and evaporating the solution to crystallization.
The amido acid forms a compound with tin which crystallizes from the HCl together with stannous chloride.
Copper quadrantoxide, Cu4O, is an olive-green powder formed by mixing well-cooled solutions of copper sulphate and alkaline stannous chloride.
The colour can be brightened by adding a small proportion ofstannous chloride to the mordant or it can be added to the dye bath towards the end of the dyeing.
Stannous chloride added to the mordant gives brilliancy and fastness to the colour.
