Gold, glitter and glamour! I'm mixing up a big batch of Gold ink for this weeks production. I've talked about mixing gold from powder pigments in previous Tool Tuesdays - but I didn't talk about storing or keeping them.
When I was going though my golds this morning - some of them had gone bad. It's not an obvious thing at first, but it's as subtle as a stale smell or the ink not flowing out of the nib as smoothly as it should.
Mixing powder pigments requires gum Arabic - a food grade product - to give your pigments stability and keep them stuck to the paper. But over time, Gum Arabic goes bad, and your inks can become stale or even mouldy!! Even if you do mix your pigments with distilled water, there is no escaping the inevitable!
There are some steps you can take to make your inks last a little longer:
-Mixing in small batches helps to control and prevent waste.
-Letting your inks dry out after every and re-hydrate them before you need them.
-Some recommend refrigeration of your inks to extend their life.
