Silver clays come in lump/clay form. If you consider that the clay is a little dry you can add distilled or demineralised water to refresh the clay’s consistency. In addition to this you can also use Kim’s Clay Spray, which is a metal clay hydrator.
Dry Clays On low heat
Suggested firing temperature in kiln or on open shelf
On 1″ kiln blanket
Ramp at speed 4 or 900C/1652F
To hold a temperature of 910C/1670F for 1.5 to 2.5 hours depending on the size and thickness of your piece.
On a kiln shelf or blanket, warm up the piece by moving the torch flame around the piece slowly, allowing the piece to heat up. First you will see a little smoke as the binder burns out then a little flame. Place your flame onto piece in a circular motion bringing it to a nice pick colour and continue for 12-15 minutes. If it starts to become shiny pull your torch away a little as this is the sign of melting. Once cool then ready to brush with brass brush and burnish/polish.
