Orton Small Pyrometric Cones - 50 Pack

Monitor ceramic kiln firings with Orton small pyrometric cones. Each box contains 50 cones of the selected number: 04, 05, 06, or 6.

• Small cones for use in a compatible Kiln-Sitter.
• May also be used as witness cones with a suitable cone holder or plaque.
• Help indicate heatwork, the combined effect of time and temperature during firing.

Choose the cone number carefully: cone 06 and cone 6 are different firing ranges. Use the current Orton cone chart and your kiln, clay, and glaze instructions to select the appropriate cone. Cone holders are not included.

For cones that stand directly on a kiln shelf, shop our Orton self-supporting cones. Browse the full Orton collection.
