The following should be observed when handling glassware, EXCEPT: a. Avoid holding two or more stemmed glasses at a time. b. Wash hot glassware in cold water to easily remove the heat. c. Avoid using any glassware to scoop ice. d. Hold glassware by the stem or the base
Answer (1)
You do not (b) wash hot glassware in cold water to easily remove the heat. Washing hot glassware in cold water can cause it to crack or shatter because of thermal shock. Glass expands when hot and contracts when cooled. A sudden change in temperature can stress the glass and make it break. This is dangerous, especially in laboratories or kitchens.
