for 24 hours. Then washed, and dyed for 24 hours with Fur Brown 2G[3] 3 grams Hydrogen peroxide 45 grams Water 1 liter Wash and dry the skins, then brush the tips with Fur Brown D[3] 20 grams Hydrogen peroxide 400 grams Water 1 liter [3] Inasmuch as most manufacturers use the same letters to designate the various dyes, any equivalent brand of fur dye may be used in place of those here mentioned. _Black on Sheared Muskrat_ The skins are killed with soda, soured, and washed, then chrome mordanted for 6 hours. Then they are dyed for 6 hours with Rodol P 1.5 grams Pyrogallic acid .7 grams Ammonia 2.0 grams Hydrogen peroxide 45 grams Water 1 liter The dyed skins are washed and dried, then tipped with Rodol D 20 grams Rodol DB 2 grams Hydrogen peroxide 450 grams Water 1 liter _Brown on Thibet Sheep Skin_ The killed skins are mordanted for 6 hours with a chrome mordant, then dyed for 6 hours with Ursol P 1 gram Pyrogallic acid 1 gram Ammonia 2 grams Hydrogen peroxide 40 grams Water 1 liter It is also possible to combine dyeings with the Oxidation Colors with Vegetable dyeings, or with Aniline Black. For example, if it be desired to produce an imitation skunk on a raccoon, and an exceptionally fast and intense and lustrous black on the tips of the hair, the skins are dyed in the bath with the Oxidation dyes, and the tips of the hair are brushed with a mixture such as described under Vegetable Colors for the production of French seal, as follows: _Imitation Skunk on Raccoon_ The skins are killed with caustic soda, soured and washed, then mordanted with an iron-copper mordant as described, and then dyed with Fur Grey R 3 grams Ammonia 2 grams Peroxide of hydrogen 45 grams Water 1 liter After washing and drying, the dyed skins are brushed over with a mixture such as used for dyeing French seal with Vegetable Colors. In a similar manner, the Oxidation Colors may be used to give a base color to furs dyed by the Aniline Black process. It is apparent from these few illustrations that a great variety of shades can be produced, and the dyeing of imitations of the better class of furs on cheaper skins is a comparatively simple matter, after an understanding of the nature of the dyes has been obtained, and a certain amount of skill acquired in working with these dyes.
