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 1657 °F is not the same as firing to cone 010 — put a witness cone on the shelf.
Cone 010 is not cone 10
The leading zero means cone 010 counts down from cone 1 — it's a low fire temperature (1657 °F). Cone 10 is 688 °F hotter (2345 °F), in the high fire range.
What cone 010 is used for
Low fire — Below the usual bisque range. Some low-fire glazes, glass, and enamel work land here; cone 010–08 appears as a soft bisque for very porous ware.

Questions
- What temperature is cone 010?
- Orton cone 010 bends at about 1657 °F (903 °C) when the kiln climbs at 108 °F per hour, and about 1679 °F (915 °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 010 in Celsius?
- 903 °C at 108 °F/hr (60 °C/hr) and 915 °C at 270 °F/hr (150 °C/hr), converted from Orton's Fahrenheit chart for self-supporting regular cones.
- Is cone 010 the same as cone 10?
- 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 010 used for?
- cone 010 sits in the low fire range. Below the usual bisque range. Some low-fire glazes, glass, and enamel work land here; cone 010–08 appears as a soft bisque for very porous ware.
- How far is cone 010 from cone 011 and cone 09?
- At 108 °F/hr, cone 011 bends 50 °F cooler (1607 °F) and cone 09 bends 31 °F hotter (1688 °F). One cone step is not a fixed number of degrees — the spacing varies across the chart.
