Potassium Dichromate (Bichromate) 100g-Dea Form Req
Reviewed by 1 customers
Very pleased with the speed of shipping and the price and quality of the product! My 5% gum bichromate emulsion, made with this product, exposes fully in 3 minutes or less in morning sunlight. Reactions are consistent and full. Highly recommended for alternative-process printers.
