Maria,
I mix a 30% ammonium dichromate solution (this is close to saturated
solution). My typical gum mix is 6cc of 14 baume gum with whatever pigment,
6 cc of water and 2cc of ammonium dichromate solution. As yu can see I
measure everything by volume.
Somebody was asking about kalium, it is potassium.
Marek, Houston
