Just a little aftercare warning about using enamels. The particles are very fine and some really can 'drift' on a breeze to settle around your workspace. I think it's a REALLY GOOD IDEA to clean up your immediate space right after working with enamels. Use a spray bottle with water and wipe everything down, don't do it dry. That'll keep all the glass dust (enamel and otherwise) settled down.
This has been a glassy public service announcement.
