What is a cold water cup (what does a cold water cup mean)

1, the glass cold water cup is easy to burst after pouring hot water, but the hot water cup will not burst. Glass cold water cups are generally determined by materials. Cups made of ordinary glass, whether double-layer or single-layer, are classified as cold water cups, because ordinary glass is easy to burst and the threat of alternating hot and cold is greater.

2, hot water cups are generally high borosilicate glass, which is low temperature; 230 degrees below zero and 850 degrees at high temperature can completely keep the shape, and the risk factor is relatively small, so it is classified as a hot water cup.
