My question in what actual strength of ferric chloride solution are you using in Damascus finishing? 29% is a more or less standard solution strength, as called for in lots of rust bluing and Damascus finishing solutions. And people refer to that or milder solutions in Damascus finishing. But what is the strength of the commonly available Radio Shack solution? My bottle also lists hydrochloric acid as an ingredient.
If I take my 29% solution and cut it 1:1 with water, my result is 14.5%, if I cut it 1:1 again I get 7.25%. But I don't know what the strength of the Radio Shack solution is from the bottle.
I don't remember enough chemistry to remember if more that 29 Grams will dissolve in 61cc of water.
