Gum Arabic inks: | 1 part | gum arabic | |   | | | | 2 parts | water | | - Soak one part Gum Arabic in two parts of water and let stand overnight.

Shellac (India) inks: | 1 part | shellac | |   | | | | 1/4 part | pure borax (not grocery store variety) | |  | | | | 2 parts | distilled water | | - Heat slowly in a double boiler, until shellac dissolves.
