DIRECTIONS FOR DYEING 
 
 ACID COLORS 
 
 Nos. 401-435 
 
 These are dyed in a gum soap bath, broken with Sulphuric Acid. 
 With the Eosine brand it is advisable to employ Acetic Acid. 
 
 The Diamond Fast Purples should be dissolved with a small per- 
 centage of Ammonia, which is to be added to the powder and boiling 
 water poured over it. 
 
 BASIC COLORS 
 
 Nos. 436-446 
 
 These colors are generally dyed in a gum soap bath, broken with 
 Acetic or Sulphuric Acid; Sulphuric Acid is used especially when 
 dyeing in combination with Acid colors. 
 
 SULPHON AND DIRECT COLORS 
 
 Nos. 447-452 
 
 These are dyed in the same manner as the Basic Colors — Acetic 
 Acid is, as a rule effective enough to exhaust the bath. 
 
 ALIZARINE AND CHROME COLORS 
 
 Nos. 453-455 
 
 Add the well dissolved color and 10-20% Acetic Acid to the Dye 
 Bath at a temperature of 100-120 degrees Fahr. Bring slowly to boil 
 and boil for one hour. Should the bath not exhaust sufficiently add 
 more Acetic Acid — after this, treat with Bichrome for ?4 hour in a 
 fresh bath, boiling gently: — rinse, soap and acidulate. 
 
 CHROME MORDANT 
 
 No. 456 
 
 Dye in a gum soap bath, broken with Acetic Acid. Work for k \ 
 hour at 120° Fahr., warm up to 195° Fahr. in J4 hr., and dye at this 
 temperature for 1 hr. Rinse, soap at the boil and acidulate. 
 
 SULPHUR COLORS 
 
 Nos. 457-462 
 
 Dissolve with the same amount of Sodium Sulphide Crystals with 
 the addition of the same amount Glucose. Add this solution to the 
 Dye Bath at 180-200 degrees Fahr. then add 30-60% Glaubersalt, and 
 finally add, shortly before entering the goods, Bicarbonate of Soda, 
 corresponding to about half the weight of the color. Work for aboul 
 half an hour, then squeeze out the silk and expose to the air for a 
 short time. Rinse well — soap at the boil and acidulate with Acetic 
 Acid. 
 
 DEVELOPED COLORS 
 
 No. 463 
 
 These are dyed in the same way as Direct Colors, — rinsed well and 
 diazotised cold for 15-20 minutes with — 
 
 2 l / 2 % Nitrite of Soda (Dissolved in water) 
 
 7}4% Hydrochloric Acid (32 degrees Tw.) 
 
 The goods are again rinsed and developed for 15-20 minutes in a 
 cold bath with the developer, Beta Naphtol. In order to dissolve the 
 latter, use 34 the amount of Caustic Soda to the weight of the Beta 
 Naphtol. After developing, rinse and soap if necessary.
