 Laundry Ink 



Aniline oil 85 parts 



Potassium chlorate 5 parts 



Water 44 parts 



Hydrochloric acid 



(Sp. gr. 1. 124) 68 parts 



Copper chloride 6 parts 



Mix the aniline oil and the potassium 

 chlorate with 26 parts of water and heat 

 in a capacious dish on a water bath from 

 175 to 190° Fahrenheit until the chlorate 

 is dissolved. Then add half of the hy- 

 drochloric acid and heat until the mix- 

 ture is dark. Dissolve the copper chlo- 

 ride in the rest of the water, add to the 

 solution the rest of the hydrochloric acid, 

 add this to the mixture on the water 

 bath and heat until the mixture has a 

 red-violet color. Pour the mixture into 

 a glass stoppered bottle, let stand until 

 no more precipitate forms, then decant 

 off the clear layer of liquid and bottle it 

 for use.
