What is the formula for mixing Cupric Nitrate granules with water for electrolytic etching on silver?
According to Ben Dory in this article he wrote for SNAG, it's 1 part cupric nitrate to 4 parts water, by weight.http://www.snagmetalsmith.org/wp-content/uploads/2015/11/TechArticle_Nov_2015.pdf
Thank you so much! A very thorough article!
No problem, hope it works for you.
