Self supporting cones 10 pcs/box #9

Self-Supporting Cone #9 comes in 10pcs/box

Orton 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 at 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.

Cones are made from carefully controlled compositions. They bend in a repeatable manner (over a relatively small temperature range - usually less than 40° F). The final bending position is an indication of how much heat was absorbed. 

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