Final answer:
Using chipped or cracked glassware is false and unsafe. Pyrex is less susceptible to breaking from thermal stresses due to its small coefficient of linear expansion. Safety equipment should be used when dealing with broken glass.
Step-by-step explanation:
Chipped or cracked glassware is false to use, especially in a laboratory or cooking context, because it may lead to accidents or contamination. It is important to use personal protective equipment like gloves and goggles for safety. When glassware breaks, instead of touching it with your hands, it should be cleaned up with a dustpan and broom to prevent injury.
Thermal Stresses in Glass Cookware
Thermal stresses caused by uneven cooling can easily break glass cookware. However, Pyrex®, known for its small coefficient of linear expansion, is less susceptible. This means that as Pyrex heats up or cools down, it does not expand or contract as much as typical glass does, reducing the risk of breakage due to sudden temperature changes.
