CoorsTek® Coal Moisture Testing Ceramic Crucibles - Combustion Type
CoorsTek® porcelain combustion capsule style crucible has a rounded bottom and is glazed inside and out, except for the rim. CoorsTek® chemical-porcelain ware has thermal-shock resistance. To prolong the life of your CoorsTek® labware be sure to follow gradual heating and cooling rates. Use an oven or hot plate as an intermediate step when quicker heating/cooling rates are required. Gradually increase flame intensity when using a gas burner. Avoid contact of heated ware with a cold surface. Carefully inspect your ceramic labware prior to each use. Do not use any product that appears defective.
