Orton Cones, JR. Small Pyrometric Cones - - we carry only the Jr Cones in the pyramid shape - not the bar cones.
The pyramid cones are more flexible: you can put your cone setter in the very middle for a true cone fire; push the setter to the thinner part of the cone for a slightly cooler fire; push the setter to the thicker part of the cone for a slightly hotter fire. Sometimes a color or a glaze just needs that special touch of firing!
Please choose your Cone size in the drop down box, along with the quantity. Each box of Cones contains 50 cones. ORTON Cones are the most trusted Pyrometric Cones for glass and porcelain painters. Accepted Standard since 1896.
