Self Supporting Cones
Self supporting Orton cones are an essential part of any ceramic studio’s firing process. They offer one of the most accurate and dependable ways to monitor heatwork in the kiln. As part of the broader range of Orton pyrometric cones, these self supporting cones eliminate the need for plaques while still delivering the same high level of precision as traditional Orton Large Cones. Their built-in design ensures the cone stands at the correct height, helping potters monitor the effect of temperature and time on their clay, glazes, and ceramic materials with confidence.

Advantages of Self Supporting Pyrometric Cones
Self supporting cones are the most accurate and easiest-to-use witness cones available, offering the same information as Orton Large Cones in a more convenient, plaque-free form. Because these Orton self supporting cones can be placed directly on any flat kiln shelf, they simplify setup and support consistent, repeatable results.
Made from carefully controlled compositions, Orton pyrometric self supporting cones bend in response to heatwork rather than just temperature, giving potters an accurate indication of how their ceramic pieces have fired. Whether working with hot clay, decorative glazes or functional pottery, potters can rely on these cones to reveal whether the kiln reached the correct temperature range, how evenly it fired, and whether any adjustments are needed for future firings.

Why Are Self Supported Cones Recommended?
Self supporting cones are recommended by glaze and kiln manufacturers because they provide an accurate representation of heatwork across a variety of kiln environments. For potters using electric, gas or wood kilns, these cones help confirm that the work has received the correct amount of heat to mature correctly.
Orton self-supporting cones are ideal for routine firing checks, diagnostics, and quality control due to their consistent height and built-in angle support, which provide reliable bending behaviour. For studios aiming for precision at every stage, these cones offer dependable insight into the effect of temperature and time on ceramic outcomes.
