Aussie Metal Clays require to be fired in a Kiln using Activated Coconut carbon and the firing schedules have 2 parts.
Please remember this firing schedule is based on a cold kiln and thickness of the piece is also something you need to work out. If a piece is any thicker than about 6mm thick you may need extra time due to the thickness of the piece.
Rehydrating Aussie Metal Clay Make sure you use DISTILLED or DEMINERALISED WATER as it hydrates the clay better than ordinary water. Keep any moist clay in a sealed container so it doesn’t dry out.
1st Stage Fire:
Full ramp 995°C / 1823°F to reach 350°C/662°F and hold for 15 minutes for up to 8 cards, and 30 minutes for over 8 cards. Let cool to below 200°C / 392°F or lower before continuing to 2nd stage.
2nd Stage Fire:
Cover with 15-18mm Activated Coconut Carbon.
Full Ramp to a hold
Temp of (range between) 759°C / 1398°F - 784°C / 1443°F for a minimum hold time of
2 to 2 1/2 hours.
Do test pieces first to see correct temperature for your kiln. Aussie Metal Clay suggests testing for the correct temperatures in your kiln for each color of clay by starting at the lowest temperature (above) and working up in increments of approximately 5°C / 8°F each firing until you reach a perfect sintering temperature of your kiln. Your Kiln temperature may need to be modified to suit – not all Kilns fire the same. Remove your pieces from the activated coconut once cool and your pieces are ready to brass brush, tumble & polish.
Shrinkage: Between 12 & 15%
