Ortonkägla 5½, 1203-1225 °C

ORTON CONE 5½, 1203-1225°CCones 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.Please read more i our data sheet, click on DATA tot the left of the product image.
