2 quarts of water with 8 ounces of starch, are to be mixed and boiled;
add 2-1/4 ounces of a liquid Prussian blue colour, prepared by
triturating three quarters of an ounce of that pigment with as much
muriatic acid, leaving the ingredients to react upon each other for 24
hours, and then adding three quarters of an ounce of water.
Add 4 ounces of liquid perchloride of tin (oxymuriate).
Mix all together, and pass through a searce. This colour is not very
fast; cloth printed with it will bear only rinsing.
