Did You Know?

1. Contrary to popular belief, not all glass cups are microwave safe. The type of glass used in Pyrex or borosilicate cups is specially designed to withstand high temperatures, making them safe for use in microwaves. However, other types of glass cups, such as recycled or decorative glassware, may not be microwave safe due to their composition.

2. Microwaving glass cups can lead to an uneven distribution of heat within the drink. Glass is a poor conductor of heat, so it may take longer for the liquid to warm up compared to using a microwave-safe ceramic or plastic cup. Stirring the drink at regular intervals can help even out the temperature.

3. Extreme temperature differences can cause glass cups to shatter in the microwave. If a glass cup is extremely cold, such as when it has been in the freezer, placing it directly in the microwave can result in a thermal shock that causes the glass to crack or break. It is recommended to gradually warm up the glass to room temperature before microwaving.

4. Adding a wooden stir stick or small metal spoon to the glass cup can help prevent boiled liquids from superheating. Superheating occurs when a liquid reaches a temperature above its boiling point without actually boiling. Placing a stir stick or spoon in the cup creates nucleation points, preventing the liquid from becoming superheated and potentially exploding when disturbed.

5. When microwaving glass cups, it is important to exercise caution when removing them from the microwave. Glass can retain heat for longer periods than other materials, so the cup may be much hotter than it appears. Using oven mitts or a kitchen towel to handle the cup is advised to prevent burns from accidentally grabbing the hot glass.
