Now you're going to have to explain how that acid grading works!
Have no problems with using different grades of paste to make coarse
and fine glass. I use an old mirror as the base plate and have
achieved reasonable results.
The idea of acid etching is appealing and I wonder if the acid packs
are available in the UK from our local friendly stained glass
shops.... How would you translate coarse to fine acid to someone who
makes pretty glass windows?
Cheers,
