BTW pure copper dosn't work to well you need something like copper sulfate to make green and blue fire

You can use stump remover....right??

I plan on doing some brass etching.

nice idea... It looked like you might have got the couch though.

Sounds like in the vid someone was asking what was the smell. You didn't get into trouble did you?

Stump remover i think is usually KNO3 , not good for colours , not sure about etching

From what I've read stump remover is 100% copper sulfate.

 

[DashApple]

Quite a few of them are KNO3 based ones as it contains nitrogen , which is one reason its used to kill tree stumps , I guess it just depends on the brand

 

[Tech_Junkie]

Didnt know that, I assumed they were all the same. I'll have to do some more snooping for the brand name.

According to wikipedia, they use KNO3

I think I got cultures mixed. I read the tutorials on for etching on a UK board. Maybe their stump remover is copper sulfate. I know it could not have been something else, because NKO3 is not used in etching. So where can I find pure CS on the open market? Is there a product that is 100% CS? I know I can buy it, but its usually cheaper buying it as a use for typical home uses.

KNO3 is an oxidizer and as such is sold as stump remover. Sorry T_J but copper sulfate may work but is 10 times more expensive than KNO3 it has COPPER in it so I doubt if it's sold as stump remover but it could be I don't know but it would not work as well for sure.
