Orton SSB Self Supporting Cones Mid-Range Assortment Pack
$10.49
Mid-Fire Self Supporting Cones with 6 each of cone 4,5,6.
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 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.
Self Supporting Cones are recommended by glaze and kiln manufacturers to achieve the best results.
Product Overview
The mid-range cone pack is a cost effective way to ensure your kiln is firing to the correct temperature without needing to buy an entire box of each!
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.
