Cone 14 temperature
Orton cone 14 bends at 2489 °F (1365 °C) at 108 °F/hr and 2523 °F (1384 °C) at 270 °F/hr. It sits in the above studio range range — cone 38 of 38 on the chart, counting up from 022.

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 2489 °F is not the same as firing to cone 14 — put a witness cone on the shelf.
Cone 14 is not cone 014
Cone 014 — with the leading zero — is 1004 °F cooler (1485 °F), in the low fire range. Read the zero as “oh”; a glaze labeled for one will not behave at the other.
What cone 14 is used for
Above studio range — Hotter than nearly all studio work. Used for some porcelains, refractories, and industrial ceramics; most studio kilns are not rated for it.

Questions
- What temperature is cone 14?
- Orton cone 14 bends at about 2489 °F (1365 °C) when the kiln climbs at 108 °F per hour, and about 2523 °F (1384 °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 14 in Celsius?
- 1365 °C at 108 °F/hr (60 °C/hr) and 1384 °C at 270 °F/hr (150 °C/hr), converted from Orton's Fahrenheit chart for self-supporting regular cones.
- Is cone 14 the same as cone 014?
- No — and this is the most common cone mix-up. Cones with a leading zero count down toward cone 1, so cone 014 is cooler than cone 14: about 1485 °F versus 2489 °F at 108 °F/hr, a difference of 1004 °F. Read the zero as "oh", not as nothing.
- What is cone 14 used for?
- cone 14 sits in the above studio range range. Hotter than nearly all studio work. Used for some porcelains, refractories, and industrial ceramics; most studio kilns are not rated for it.
