Re: gum mixes
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.
