Why are there cracks and traces of glue on the new bought stone kitchenware?
Natural marble is a mixture, made up of a variety of substances. Stone line, due to the color difference which generate because of different contents of some substances in the stone, is much like cracks; stone line, as part of the ore, does not affect product performance; therefore, the saying that stone kitchenware with stone line is easy to crack is not true.
The stone is heavy:
The specific gravity of stone is about 2.63-2.75 tons per cubic; the specific gravity of aluminum is about 2.7 tons per cubic; the specific gravity of iron is 7.85 tons per cubic; the specific gravity of water is 1 ton per cubic; the specific gravity of stone and aluminum are almost the same. They are light-weight materials, but some stones are made very thick so that they seem to be very heavy.
Is not the stone heated by oven easy to crack?
The oven is a closed heating source so that it can heat the stone kitchenware all together, then avoid partial hot and reduce thermal shock; therefore, there are fewer cracks.
