K-23 Soft Insulating Fire Bricks are a special type of brick that can handle high temperatures and act as insulation. They are used as a lining in the interior of foundry furnaces, forges and ceramic kilns to keep in the intense heat.

These are soft bricks that can be cut with a hacksaw to form smaller bricks or to add channels for heating elements. They can be drilled with a hole saw to create an opening for a gas burner as well. The bricks have a working temp rating up to 2300 Degrees F. which makes them suitable for high fire ceramic use. For Consistent Cone 10 or hotter firings we recommend the K-26 Brick for a longer performance.

Each straight brick is 9" x 4-1/2" x 2-1/2"
