About Orton Pyrometric Cone 07 - Box of 25
The Orton Pyrometric Cone 07 - Box of 25 contains 25 ceramic cones designed to monitor heatwork during the firing process in kilns, specifically for low-fire ceramics. Cone 07 is calibrated to bend at approximately 984°C (1,803°F), making it ideal for projects like earthenware or certain low-fire glazes. The cones soften and bend once the kiln reaches the appropriate temperature, providing a clear visual indication that the firing is complete. This box of 25 cones is a practical option for ceramic studios, schools, or artists who frequently work with low-temperature firings, ensuring they have enough cones on hand for multiple firing cycles.
These pyrometric cones are an essential tool for achieving consistent results in ceramic work by accurately measuring the combination of time and temperature (heatwork). By using the Orton Cone 07, potters can ensure their pieces are neither under-fired, which could result in weak or fragile ceramics, nor over-fired, which may cause glaze defects or distortions. The box of 25 allows for ongoing monitoring across several firings, making it a reliable and cost-effective choice for anyone working with low-fire ceramics, guaranteeing consistent and high-quality results.
