CORELITE
CORELITE is a high thermal shock resistant extruded refractory material based on a rich mullite/cordierite composition, suitable to cone 10 firing temperatures. The hollow shelves are available in many shapes and sizes, including: rectangles, rounds, half-rounds, octagons, and decagons. A wide assortment of tooling and dies are available to accommodate both standard and specialized kiln configurations.
Round
Half or Full round shelves available.
Rectangular
POST
Kilns posts 1-1/2″ square. These post are used to support kiln shelves when firing. They are available in lengths from 1/2″ to 12″ to utilize the maximum stacking space in your kiln.
Kiln Wash
Kiln Shelf Wash prolongs kiln shelf life and makes glaze drippings easy to remove.
kiln Cement
Cracks and chips in kiln refractory can be permanently sealed with AMACO® Kiln Cement. Mix water with the dry cement for a smooth, plastic consistency.
Note: 1 lbs. is premixed liquid and 5 lbs. is dry that requires you to mix the kiln cement.
The prepared cement is ready for immediate use. When mixed with coarse grog or pieces of refractory, cement may be used to repair large holes in firebrick. WARNING: Do not allow direct contact with elements and electrical wiring.
Pyrometric Cones
Pyrometric cones are used worldwide to monitor ceramic firings in industrial kilns, pottery kilns, and small hobby kilns where the consistent temperature is important to the quality of the final product being fired. Pyrometric cones measure heat-work, the effect of time, and temperature. Over time, kilns sometimes drift from their setpoint even though "Nothing has changed". Pyrometric cones will be the first to let you know your ceramic firing is under control or that subtle changes are taking place within your kiln, allowing you to take corrective action before they impact your ware.
Pyrometric Cones
Small 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.
Pyrometric Cones
Orton Bars were specifically designed to function in the Kiln-Sitter®.
The uniform shape makes consistent placement easy without affecting firing. The novice or beginner will welcome its ease of use, while those practiced in firing will appreciate the consistency.
Pyrometric Bars have the same temperature equivalents as small cones.

Orton Cone Chart
Please refer to the Orton Cone Chart and use the small cone numbering system to determine your equivalant temperature.
