Cone 4 - Pyrometric Cones - Orton Cones - Small - Box of 50 (SRB-4)
Penguin Pottery - Cone 4 - Pyrometric Cones - Orton Cones - Small - Box of 50 (SRB-4) Commonly used in the Kiln-Sitter to adjust shut-off Can also be used as "witness" cones on kiln shelves if space is limited Cone holder / plaque required if placing on shelf (NOT INCLUDED) Box of 50 cones Small Cones are commonly used in the Kiln-Sitter. The tapered shape allows some flexibility to adjust shut-off by placing the thinner or thicker portion of the cone under the sensing rod. Small Cones can also be used on the kiln shelf as miniature witness cones when space is limited. They require mounting in cone holders or plaques at an 8° angle and a width of 15/16 of the cone exposed above the cone holder. Small Cones used on the kiln shelf deform at about 9°F after Large or Self-Supporting Cones of the same number. NOTE: CONE HOLDER / PLAQUE NOT INCLUDED. Please note that pyrometric cones usually arrive with pairs stuck together, you need to snap them apart before you use them. This is done to keep breakage low while in transit.
