Screen printing on glass is
Screen printing on glass is a pretty broad topic and ranges from traditional screen printing of wet enamels to dry powder. Stacy Lynn Smith (http://stacylynnsmith.com) works for Bullseye Glass and developed a pretty amazing approach to using traditional screen printing techniques to print with dry glass powder on glass. Unfortunately, I’m not aware of any cmprehensive online instructions.
