❓ Frequently Asked Questions
What is the difference between borosilicate glass and regular glass?
Borosilicate glass, such as Pyrex, is made from a mixture of silicon dioxide and boron oxide, which makes it more resistant to thermal shock and less likely to shatter or explode when heated. Regular glass, on the other hand, is made from pure silicon dioxide and can be more prone to shattering or exploding when heated.
Can I use a glass cup with a metal rim in the microwave?
No, it’s not recommended to use a glass cup with a metal rim in the microwave, as the metal can cause sparks and fires when heated. Instead, opt for a glass cup with a flat bottom and a wide mouth for even heating.
How do I clean a broken glass cup?
When cleaning a broken glass cup, carefully sweep up the broken glass using a broom and dustpan. Avoid touching the broken glass, as it can cause cuts and injuries. Once the broken glass is removed, wash the area with soap and water to clean it thoroughly.
Can I use a glass cup with a handle in the oven?
When it comes to using a glass cup with a handle in the oven, it’s best to avoid it. Handles can cause sparks and fires when heated, potentially causing serious injury or damage. Instead, opt for a glass cup with a flat bottom and a wide mouth for even heating.
What is the best way to store a glass cup after microwaving it?
After microwaving a glass cup, it’s essential to let it cool down completely before storing it. Avoid storing a glass cup near a heat source or in a humid environment, as this can cause it to shatter or explode. Instead, store the glass cup in a dry, cool place, such as a cupboard or drawer.
