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 1252 °F is not the same as firing to cone 019 — put a witness cone on the shelf.
What cone 019 is used for
Decorating fire — The lowest cones — used for overglaze work fired onto already-glazed ware: lusters, china paints, and decals. Too cool to mature clay or glaze.

Questions
- What temperature is cone 019?
- Orton cone 019 bends at about 1252 °F (678 °C) when the kiln climbs at 108 °F per hour, and about 1283 °F (695 °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 019 in Celsius?
- 678 °C at 108 °F/hr (60 °C/hr) and 695 °C at 270 °F/hr (150 °C/hr), converted from Orton's Fahrenheit chart for self-supporting regular cones.
- What is cone 019 used for?
- cone 019 sits in the decorating fire range. The lowest cones — used for overglaze work fired onto already-glazed ware: lusters, china paints, and decals. Too cool to mature clay or glaze.
- How far is cone 019 from cone 020 and cone 018?
- At 108 °F/hr, cone 020 bends 93 °F cooler (1159 °F) and cone 018 bends 67 °F hotter (1319 °F). One cone step is not a fixed number of degrees — the spacing varies across the chart.
