General Information:

Self-Supporting Cones are the most accurate and easiest to use witness cones available. They provide the same information as Orton Large Cones. The advantage of Self-Supporting cones is that they are the correct height (1 3/4" exposed above the base) and have the 8 degree bending angle built in. They do not require plaques. Self-Supporting cones can be set on any flat surface.

Self-Supporting Cones are available for use from 1087°F to 3106°F (586°C to 1708°C). Cones are numbered from 022 to 32. Cone 022 is the cone that will deform at the lowest temperature 1087°F (586°C) and cone 32 is the cone that deforms at the highest temperature 3106°F (1708°C).

Self Supporting Cones are recommended by glaze and kiln manufacturers to achieve the best results.
