Orton | LRB016
Large Regular Pyrometric Cone 016
Cone 016 in Orton's large regular series, the witness cone that stands on the kiln shelf beside the ware. Its bend after the firing shows whether the kiln reached, missed or passed cone 016, which a controller reading on its own cannot tell you.

This is Cone 016 in Orton's large regular LRB series, the standard witness cone for the kiln shelf. Orton lists it bending at 769°C (1416°F) when the last 100°C of the firing climbs at 60°C an hour, and at 794°C (1461°F) at 150°C an hour. A cone responds to time and temperature together, not temperature alone, so the number it bends at depends on how fast the kiln is climbing. Orton lists cones in this part of the range for overglaze decoration, lustres, enamels and decals, and for fusing, slumping and decorating glass. The cone does not stand on its own. Set it in a cone plaque, clay pat or wire holder with 51 mm (2 in) showing above the mount and leaning at 8 degrees. If that height is out by 6 mm (¼ in) the bend shifts by more than half a cone.
