Gary Oak trees in the churchyard at St. Peters Church, Duncan, BC.
About 8 cups of hulls to the same amount of water and let boil. Add in one large old rusty chain, rusty saw blade (at the bottom).and some rusted parts. The iron oxide has a reaction with the acorn liquid and turns it from a similar warm walnut brown colour to a beautiful silver-grey colour. The recipe is from the book ‘Making Ink” by Jason Logan.
