Hi Cathy.  I think you can put enamel on a sheet of metal, fire it, then break it off by bending the metal.  Since fine silver is cleaner than copper I would try that.  Re use the sheet.

You can the chips as follows produce: Sieve a 1 mm thick enamel shift onto a stainless steel and fire it. If the sheet cools down, the enamel shift chips off.  The flake you can crush. Instead of stainless steal you also can use or copper-foil. The disadvantage is, that the enamel flakes sticks onto the foil and  have on the back a thin shift of cinder. If you wrinkle the foil the enamel shift chips off in many small pieces.

A friend of mine makes from such flakes pictures, which looks like mosaic. He sorted the flakes by color and glues with wall paper glue it piece by piece on a pre-enameled copper sheet and fired it again. A LOT of work, but the effect is very special.

I have come across some flakes of enamel that I am using in my work. I wonder how they were made. I imagine that lead based enamels were sifted and melted onto a surface that did not fuse to the enamel. The enamel was then scraped off into a pile of small chips (quarter inch or smaller). Is anyone familiar with this technique?
