A few typical formulas will serve to illustrate the general methods of employing the Oxidation Colors:
_Brown Sable Imitation on Unsheared Rabbit_
The skins are killed with soda, soured, and washed, then mordanted with
Bichromate of soda 2 grams Copper sulphate .25 grams Cream of tartar 1 gram Water 1 liter
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.
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
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:
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.
