CoorsTek® Porcelain Spot Plates & Color Reaction Plates

The CoorsTek® porcelain spot plate and color reaction plate is glazed except for the bottom surface. It has twelve depressions. CoorsTek® porcelain & ceramic labware has excellent thermal-shock resistance. It remains the responsibility of the user to determine the suitability for use. 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. Hardness of this labware is 57.5 on the Rockwell 45N scale. Refractory Qualities include a fusion point of1670° C and a softening point of 1400° C.
