Fast — typical of a quick electric firing
Orton self-supporting regular cones; rate measured over the last 200 °F of the firing. Source: Orton °F chart; °C converted. Cones measure heat-work, so a controller set to 2345 °F is not the same as firing to cone 10 — put a witness cone on the shelf.
Cone 10 is not cone 010
Cone 010 — with the leading zero — is 688 °F cooler (1657 °F), in the low fire range. Read the zero as “oh”; a glaze labeled for one will not behave at the other.
What cone 10 is used for
High fire — Traditional stoneware and porcelain, especially in gas reduction. Cone 10 is the classic high-fire target; cone 9–10 is where shinos, celadons, and copper reds live.

Questions
- What temperature is cone 10?
- Orton cone 10 bends at about 2345 °F (1285 °C) when the kiln climbs at 108 °F per hour, and about 2381 °F (1305 °C) at 270 °F per hour. Cones measure heat-work — temperature over time — so the faster you fire, the hotter the kiln has to get for the same cone to bend.
- What is cone 10 in Celsius?
- 1285 °C at 108 °F/hr (60 °C/hr) and 1305 °C at 270 °F/hr (150 °C/hr), converted from Orton's Fahrenheit chart for self-supporting regular cones.
- Is cone 10 the same as cone 010?
- No — and this is the most common cone mix-up. Cones with a leading zero count down toward cone 1, so cone 010 is cooler than cone 10: about 1657 °F versus 2345 °F at 108 °F/hr, a difference of 688 °F. Read the zero as "oh", not as nothing.
- What is cone 10 used for?
- cone 10 sits in the high fire range. Traditional stoneware and porcelain, especially in gas reduction. Cone 10 is the classic high-fire target; cone 9–10 is where shinos, celadons, and copper reds live.
- How far is cone 10 from cone 9 and cone 11?
- At 108 °F/hr, cone 9 bends 45 °F cooler (2300 °F) and cone 11 bends 16 °F hotter (2361 °F). One cone step is not a fixed number of degrees — the spacing varies across the chart.
