_Brown._--Dye with 20 lb. Amidazol cutch, 5 lb. soda ash and 150 lb.
salt, working at the boil for one hour, then lift, wash thoroughly and
dry. By after treatment in a bath of 3 lb. potassium bichromate and 3
lb. sulphuric acid the colour is made fast to washing. The shade is not
altered.

working at the boil for one hour, then lift, wash and dry.

All the Amidazol dyes are very fast to washing, acids, etc. They can be
treated with sulphate of copper or peroxide of sodium when they produce
good shades. They may even be diazotised and developed with
beta-naphthol and phenylene diamine. The pale tints got by using from 2
to 4 per cent. of dye-stuff are useful ones, as also are the medium
shades with 10 per cent. of dye-stuff.

salt, 10 lb. soda and 5 lb sulphide of sodium; work at the boil for one
