COCONUT SHELL-BASED CARBON -- Coconut based activated carbon produces a natural terra-cotta bronze color used in sealed Firing Container for BronzClay.
1 lbs. is enough to fill the large container all the way to the top. If you don't let air get to the carbon until it is cool, you can re-use it many times.
To prepare the carbon for use, place it inside the container, cover with the lid and fire for 30 minutes at 1550 degrees F. Coal -based, acid-washed carbon creates a color patina on pieces as they're fired. Coconut shell-based carbon preserves the natural color of your pieces.
