Fluxes for Enameling, Firing Temperatures, and Color Charts

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.

Fire at 1425 – 1450 degrees

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.

    Does anybody know an address where I can buy sink free eutectic paste and sheet solder?

    I ordered with Beth Katz (who wrote an article about the eutectic paste solder) but she is not able to deliver. I found some eutectic wire solder but like to have the paste as well.

    Thanks.

      Ingrid,

      In asking around eutectic solder would not have zinc in it, as it should be sliver and copper only. Thompson”s Enamel sells it in a wire form which you could melt it and pour into a crucible. Then use a hand file to shave it very fine and add soldering flux to it to make your paste. I know plique a jour artist like Timofeev Valeri makes he solder that way. But he does not add flux, just sifts it on.

      Good luck, Patsy
