• After firing, this product turns into high quality silver (higher than 99% silver). *All soldering must be done after firing as the soldering temperature is lower than the firing temperature.
• ST piece will eventually tarnish over a much longer period of time. The tarnishing speed varies by climate, location, season and other conditions.
• Use of ST with the other Art Clay series (clay, paste and syringe types), requires that the pieces be fired at the designated ST temperatures.

Firing

Firing with gas stove, butane torch and electrical kiln is available. *Kiln firing is suggested, since firing time is 30 minutes.
