Firing brick for use with a blowtorch or in a kiln. This will stop a lot of the heat going through and will ensure an even firing due to the embedded metal.

Please note do not use directly on a tabletop as some heat will pass through and will damage the surface. We use an upturned ceramic bowl. But you could use a flowerpot or you can place it in your fireplace or maybe even on a raised wire grill from your oven!

Remember to wash your hands and cooking surfaces afterwards as it's a little dusty.
