Self-Supporting Cones are one of the most accurate and easiest-to-use witness cones available. They provide the same information as Orton Large Cones.  Self-Supporting Cones are recommended by glaze and kiln manufacturers to achieve the best results.

Do Not Require Plaques!

  • Built with the correct height (1-3/4" exposed above the base) and the 8 degree bending angle.
  • Ready to use without mounting.
  • Can be set on any flat surface.

Temperature Ranges

  • Cones are numbered from 022 to 32.
  • Cone 022 deforms at the lowest temperature (1087°F).
  • Cone 32 deforms at the highest temperature 3106°F (1708°C).

To determine the best maturing temperature for your ware, we recommend using three cones for firing: First one for the desired maturing temperature, 2nd one right below that temperature, and 3rd one right above it.


Twenty-five cones per box.  Each cone approximately 2.5" tall.
