Orton cone 7, 1239-1257 °C

ORTON CONE 7, 1239-1257°C

Cones are slender pyramids made with carefully controlled ceramic compositions. Bars are small uniformly shaped 
rectangles made from the same compositions as cones. Each cone/bar composition is identified with a number such as 04 or 06.

Cones are placed inside a kiln where they can be observed through a peephole. Orton® Self Supporting Cones are freestanding.
When cones soften and bend, this indicates that a certain amount of heat has been absorbed by the cone and hence, the ware being fired. Because ceramics and glasses can require different heat treatments, a range of cone numbers are used.
