CoorsTek® Ceramic Rose Crucibles
The CoorsTek® rose style porcelain crucible is unglazed and has a capacity of 75mL. CoorsTek® porcelain & ceramic labware has excellent thermal-shock resistance. These unglazed porcelain crucibles eliminates the possibility of a reaction between the sample contents and a (glazed) coating. To prevent thermal stress cracks on porcelain ware, CoorsTek® strongly recommends a heating/cooling rate not to exceed 200°C/hour. 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.
