I am working on stained glass and want to create groves in one inch flowers to created petal shapes by depositing frit in the groves and firing at 1400 degrees. How deep and how narrow will the cream process produce? Any Suggestions? Don
The acid cream process will etch as narrow as you’d like it to, but it will be hard to see. It doesn’t etch deep at all and is a light surface marking.
The only professional way to make grooves into the glass as you are desire is to use the sandblasting process, hydrofluoric acid, or a rotary engraver. The hydrofluoric acid process is probably the solution you are thinking of, but it is extremely dangerous. The sandblasting process is very popular these days because you can do a lot of interesting techniques with it and it’s safer than using potent acid. Sand blasting deep into the glass is more known as the sand carving process.
