Re: gum mixes
Dear Christina, I use a premixed gum solution. This is combined with either linel or old holland paints to make stock solutions which are combined with either pot or amm dichromate - usually 1:1, but sometimes 1:2 BTW thanks for your work in raising and encouraging these discussions - its always interesting to see how different gum printers work.
