Activated Carbon Coconut based 1kg
The activated carbon is used to create an oxygen reduced environment, allowing the Prometheus® Bronze and Copper Clays be sintered without oxidation. It can be re-used 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 Coconut Based Activated Carbon is packed in a Plastic Bag and you get 1 kg of carbon.
