Orton cones

Accurate firing control has been central to ceramic production for over a century. To meet this need, Dr. Edward Orton Jr. developed the first pyrometric cones to measure heatwork during kiln firings, laying the foundation for what later became the Orton Ceramic Foundation.

Today, Orton’s pyrometric cones and firing products are widely used by ceramic artists, studios, schools, and industry worldwide. Through the Orton Ceramic Foundation, the company continues to support research, education, and innovation while providing reliable tools that improve consistency and quality in high-temperature ceramic processes.
