Basic formula for ink
(The following recipe is from the International Stam Forum stamforum.com/2012/03/dyo-making.html
This will produce about 2 quarts of fine, durable ink.

3 oz oak galls
1 oz logwood shavings
2.2 oz gum arabic
1.9 oz copperas

The trick to making really, really good iron gall ink is long, slow cooking of the galls and logwood. Some recipes I’ve seen call for just tossing all four ingredients together in a jar of water and allowing it to ‘macerate’ for a few weeks. This is great if you want to write with a disappointingly grey ink. However, if you’re like me and want an rich, deep black ink, straight from the bottle then we need to prepare the ingredients a bit more.

Stage One:
Assemble, weigh and prepare the ingredients for cooking.
