PEEP HOLE COVER

Keep the heat in and the control in your hands.

This high-temperature ceramic plug fits snugly into the peephole of your Olympic electric or gas kiln. Whether you’re observing the progress of your firing or sealing in the heat for peak performance, this simple yet essential tool ensures better temperature regulation and safer kiln operation.

Features:

• Tapered shape for a secure fit and easy removal.
• Ideal for cone observation and venting during candling.

🔧 How to Use:

• Leave the peephole plug out during early firing stages (such as candling) to allow moisture and gases to escape.

• Insert the plug during mid to high firing to conserve heat and maintain kiln efficiency.

• Remove carefully using tongs or heat-resistant gloves if checking cones mid-firing.

Most Olympic kilns – electric or gas. (Need help confirming the fit? Just ask—we're happy to help.)
