Orton Self Supporting Large Cones

Freestanding large witness cones the SSB's

Self-Supporting Cones are the most accurate and and , of course, are the 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 between 1087F and 3106F (586C and 1708)C. Cones are numbered from 022 to 32*. Cone 022 is the cone that will deform at the lowest temperature (1087F) and cone 32* is the cone that deforms at the highest temperature 3106F (1708C).

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