Pyrometric Cones
Pyrometric cones are small but mighty tools that help you gauge heat work inside your kiln. They bend at specific temperatures to show when your firing has reached maturity. Perfect for tracking accuracy and making sure your pieces are fully fired.
Pyrometric cones come in a range of numbers that represent different firing temperatures, so you can pick the exact cone that matches your clay or glaze requirements. You’ll find large, self-supporting cones, as well as small cones for use in kilns with limited space. Each type gives you a visual cue that your firing is complete, which adds an extra layer of control even if you’re using a digital controller. Cones respond to both temperature and time, making them more reliable for judging the overall firing effect on your pieces. They’re affordable, easy to use, and a smart backup for any kiln setup.
