Suitable for direct firing in silver clay.

Also suitable for co-firing in Bronze or copper clay. In copper or bronze clay the stone can be baked for 4 hours in the activated carbon at 820 degrees

Instead of co-baking, stones can also be added after baking. For example, by using a setting box or chatons.

These bricks can be baked in an oven, with a torche / hand burner or on the gas stove. The bricks have been tested for 30 minutes at 850°C.

Note: Do not cool in water. The pebbles crack, become matte, change color due to the large temperature difference.

Larger stones should preferably be baked off in an oven. Place in a cold oven and allow to cool to room temperature after baking in the oven.
