I have a craftsman etcher and it's works awsome.......I have 2 other unknown brand etchers, but they don't even come close..........I don't know if sears still sells craftsman glass etchers, but it's worth checking out.
Yes, I've heard of the cream, I guess it's like acid etching........were you mask out the pattern or design you want then brush on the cream, let it sit for awile then clean off........I've never tried it though, so don't quate me on it......
Also there is the sand blasting etching, were again you mask off you pattern and blast the area with a very fine media.........I've seen small kits at wall mart for doing glasses and stuff.........I think it's worth checking out.........I'll probably give it a try just out of curiasaty
i know an artist who uses two processes. i dont know jack about etching so i wont even attempt to explain it or how he does it. just noticed a lot of surface etching now adays on peeople's cars. maybe im spoiled seeing this person's skills cause everything i see now seems to look like nothing more then scratching. wish i had more pics of his work, ones with people/figures. the etching is real deep and has a 3d effect to them.
