Fluxes for transparent and medium firing enameling. Firing time varies on the size of your jewel. I work small and like to start around a min and go up in seconds. Just a quick peak in the kiln at eye level you can see if the enamel has fused.

 

What is flux? it could be thought of as primer when you are painting a wall, or gesso on and oil canvas. It is a base coat of enamel that allows enamels of a wide range of physical properties to be use in this technique and not burn.

Fine Silver

I make enamel and cloisonne jewelry. And Fine Silver is my choice of metals. The weight of the jewel as well as the strength is a factor and in choosing the gauge of the fine silver. For pendants I prefer 20 gauge and for earrings 22 gauge.

Bovano’s #3   Leaded Flux, both of these are hard enamels and I think it is helpful in keeping the surface contamination down of the sterling silver away from the layers of enamels.

Brass  Today is Gilded Metal

Today many are asking about enameling on brass. It needs to be gilded meatl, which means it has 5% zinc and no more to be successful, with 95% bronze. You can obtain this from Thompson’s Enamel and use their unleaded enamels used for copper as long as you have no more than three firings.
