irisjeane asked: Hi Tony, I am amazed and inspired by your work! I have recently decided to give gum another try, and I’ve been using a 10% potassium dichromate solution, but I’d like to try ammonium dichromate. Would you suggest using a nearly saturated solution of 29%, or something else? Any advice is greatly appreciated. Thank you in advance!!
Hi. Thank you for your kind words about my work. I’ve been using ammonium dichromate for over ten years at a 26% saturated solution. The formula I use is 13 grams ammonium dichromate to 50ml of distilled water. Hope this helps.
