Activated Carbon - Charcoal Based for use in a kiln whilst firing base metals.

The activated carbon is used to create an oxygen reduced environment, allowing the BRONZclay to sinter. It can be reused over and over until it breaks down.

You might need to top it up a little after many firings, as small amounts will burn during the firing and turn into dust. This is a very slow process, and it will be a visible breakdown so you'll know when you need to get new carbon.

The coal-based carbon produces a colourful intense range of patinas on the BRONZclay. The patina you get differs from firing to firing, and where (and how) you place your piece in the firing pan. 

You get approximately 480 - 500g of carbon which comes in a strong plastic grip seal bag which is re-sealable. This amount is perfect for filling an SC2 firing pan. 

CANNOT BE USED WITH COPPRCLAY - copper clay must be fired in coconut shell based carbon only.
