If you’ve ever searched “clay firing temperature” or gotten confused about where bisque ends and glaze firing begins, you’re not alone. I’ve been firing kilns for decades, and even now, I double-check cone charts before every load. This visualizer helps you see what each firing cone actually means in °F and °C from delicate low-fire bisque to Cone 10 reduction. Whether you’re just getting started or refining your firing schedule, this tool will make your glaze results (and your sanity) a lot more consistent.

What is the best clay firing temperature?
It depends on the clay body, but most stoneware clays mature at Cone 6 (around 2232°F). Low-fire earthenware matures closer to Cone 04 (around 1945°F).
What temperature is bisque firing done at?
Bisque is typically fired at Cone 06–04 (1830°F–1945°F). It’s low enough to leave the clay porous so it can absorb glaze.
What’s the difference between bisque and glaze firing?
Bisque firing is the first round it hardens the clay but keeps it porous. Glaze firing is done at a higher cone to vitrify the clay and melt the glaze.
Do I need pyrometric cones for bisque firing?
Absolutely. Even digital kilns can vary. Cones confirm that the heat work matched what your controller said.
Can I fire greenware straight to glaze temp?
You can, but it’s risky. Skipping bisque means the clay can trap moisture or explode. For reliable results, always bisque first.
