Hello,
I am going to be etching some brass sheets (0.10" thick) for a
project I am working on. I will be etching them to 1/2 thickness.
Would you recommend the peroxide/muriatic solution for this, or
would something else be better/safer?

Also, would I be able to regenerate this mix with a bubbler? I will
be using the mixture as listed in the files section.

Thanks!
