It can be reused over and over until it breaks down.\u003c\/p\u003e\u003cp\u003eYou 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.\u003c\/p\u003e\u003cp\u003eThe 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. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eYou get approximately 480 - 500g of carbon which comes in a strong plastic grip seal bag which is re-sealable.
