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. 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. Need help figuring out which cone number to use? We’re happy to walk you through it.
