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.
