Recipe: Violet Logwood Ink

This logwood ink has a beautiful, blue-tinged violet hue which soon becomes much more reddish when exposed to light and turns rather brownish after a few weeks.

Processing

Step 1: Boil the logwood in water for about half an hour and then filter.
Add gum arabic to the hot liquid and stir until it is dissolved.
Potash alum needs to be dissolved in hot water before adding it to the solution.
Step 2: The ink forms little sediment, which can be left in the glass. You could decant the ink, but if you don t shake or stir it, the sediment won t bother you.

20 g Logwood, cut pieces (#36100)
100 g Water (#65000)
2 g Gum Arabic Powder (#63330)
