Cone Plaque for Standard Cones
A plaque that holds standard size witness cones upright at a steady angle, so they bend the way the cone chart expects.
$3.50
Suggested retail price. In-store prices and availability may vary by location.
Set your guide, firing and guard cones in the holes and press them in firmly so they all sit at the same angle. Place the plaque where you can see it through a peephole. Reading the bent cones after a firing shows how much heat work the ware actually received, which a thermocouple alone cannot tell you.
