• Porcelain labware is widely used in the chemistry laboratory

It has excellent resistance to all reagents except hydrofluoric acid, and is highly resistant to thermal shock while having a very low coefficient of expansion

Note: Follow gradual heating/cooling rates. Avoid contact of heated ware with a cold surface. Use an oven or hot plate and an intermediate step when quicker heating/cooling rates are required. Carefully inspect labware prior to each use and do not use any product that appears defective.

The average coefficient of expansion from 20° to 200°C is 3.56 x 10^-5 gradually increasing to 4.69 x 10^-5 at 1000°C. To prevent thermal stress cracks on porcelain ware do not exceed a heating/cooling rate of 200°C per hour.
