Orton Pyrometric Cone 04 - Box of 25

About Orton Pyrometric Cone 04 - Box of 25

The Orton Pyrometric Cone 04 is a widely used ceramic tool designed to measure heatwork in kilns, providing an accurate indication of the temperature and time needed for proper firing. Each cone in the box of 25 is made from carefully formulated ceramic material that bends and melts at a specific temperature, in this case, Cone 04, which corresponds to approximately 1,060°C (1,940°F). These cones are critical for ensuring consistency in ceramic firing, allowing artists and potters to know precisely when their pieces have been fired to the desired point, ensuring their work is properly vitrified or matured.

Orton Pyrometric Cones are easy to use; they are typically placed in the kiln and observed as they soften and bend, signalling that the correct temperature has been achieved. The cones offer a reliable way to monitor the firing process, especially when used in conjunction with kiln controllers, helping to avoid over- or under-firing. With a box of 25, ceramists are well-equipped for multiple firings, and the use of these cones ensures high-quality results by taking the guesswork out of the kiln firing process.
