Borosilicate glass has several advantages over traditional glass, including:

1. High resistance to thermal shock, making it suitable for hot liquids
2. Low thermal expansion, which reduces the risk of shattering when exposed to sudden temperature changes
3. High chemical resistance, making it ideal for use with acidic or alkaline substances
4. High clarity and transparency, making it easy to see the contents of the cup
5. Lightweight yet durable, making it easy to handle and less likely to break

These properties make borosilicate glass a popular material for laboratory equipment, kitchenware, and high-end drinkware.
