Heat Resistance: Cone was placed upright for 1 hour in 178 degrees F circulating air oven with a 1.36 kg mass suspended inside the conical section from a 2.5 inch diameter disc placed on top of the cone. JBC cone exhibited no sign of slump or sag.
Cold Resistance: Cone was placed horizontally for 2 hours in a 0 degrees F freezer with the top of the cone supported so as to make the base plumb. After 2 hours, a 2 3/8" diameter steel ball with a mass of 0.91 kg was vertically dropped through a virtually frictionless guide tube onto the cone surface. JBC cone showed to fracturing, cracking, or splitting of cone or base.
