Carbon Coal-based Acid-Washed by the Pound

Activated CARBON -- Coal-based, acid-washed carbon produces a colorful range of patinas, 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.
