can they be etched in a controlled manner using HCl?
Hi Ethan, I thought tht Hydrofluoric acid was used for glass
etching, and I would not touch it with a barge pole! I work with
viterous enamel and there's a matting salt which is a hydrofluoric
salt (sorry, don't know the chemical ID) I believe it is less
This is quite slow but does work. To remove enamel I soak the piece
for a few days, every day rinsing, scratch brushing, r& dry before
replacing in the solution.
Goggles, gloves, apron and the usual safety gear.
Interesting question though!
