Pyrometric cones are essential tools used in the ceramics industry to determine when a kiln has reached the desired level of heatwork. These small, pyramidal-shaped pieces are made from a carefully formulated combination of ceramic materials that soften and bend when exposed to specific temperatures.

Composition and Function

Pyrometric cones are composed of a mix of clay, feldspar, and fluxing agents that enable them to deform at precise temperatures. As the kiln heats up, these cones are placed alongside the ceramic ware being fired. When the kiln reaches the correct temperature, the cone softens and bends, indicating that the desired heatwork has been achieved.

Measuring Heatwork

Each pyrometric cone is assigned a number, with lower numbers representing cones that deform at lower temperatures and higher numbers indicating cones that require more heatwork. For example, a cone 06 will deform at a lower temperature than a cone 10. By using a combination of cones with different numbers, potters and ceramicists can ensure that their kilns are firing consistently and accurately.

Accuracy and Reliability

Pyrometric cones are known for their accuracy and reliability in gauging heatwork levels in a kiln. Unlike electronic temperature sensors, cones can visually show when the desired temperature has been reached, providing a tactile and reliable method for monitoring the firing process. This level of precision is crucial in achieving the desired results in ceramic production.

Overall, pyrometric cones play a vital role in the ceramics industry, offering a simple yet effective way to measure heatwork in a kiln. Their accuracy, reliability, and ease of use make them indispensable tools for potters, ceramic artists, and other professionals working with clay and ceramic materials.
