You sound like you may be able to answer this,
Read https://www.electro-tech-online.com...etching-with-nitric-acid.150753/#post-1294020 and didn't want to do a Hijack, so
years ago, I bought a fire pit ring and thought that some color would be nice, so I threw some copper tubing and had some green flames, for a while. Asked a friend about it and he said the copper had glazed over and that it could be removed with muriatic acid, so I put the copper in a bucket and covered it with the acid and left it over night, next fire, the color was back, but I noticed the acid was green, so I threw some of that on the fire and WOW, look at that color, blue, green, turquoise, just beautiful to look at, and makes for some good BS stories for young scouts by scout leaders, I gave some to a friend. I don't even bother with copper to color the fire any more, just "blue fire", as the solution has come to be known as.
My question is what am I getting when I put copper in the hydrochloric acid (the dark brown/green liquid, the light green paste at the bottom), what am I getting as it is 'consumed' by the fire, the color is very prominent when the liquid is added, but dissipates after a while, is it dangerous if you breath in any of the smoke as it burns, is it dangerous to cook over (hot dogs, etc), what's left in the ashes.
Thanks,
Jeff
