Pyrex melts at around 820°C (1508°F). It’s made from borosilicate glass, which is designed to withstand very high temperatures, making it safe for both baking and serving. Always avoid sudden temperature changes to prevent cracking.
FAQs & Answers
- What temperature does Pyrex glass melt at? Pyrex glass melts at approximately 820°C (1508°F), thanks to its borosilicate glass composition designed to withstand high heat.
- Why does Pyrex sometimes crack when heated? Pyrex can crack if exposed to sudden temperature changes, known as thermal shock, rather than gradual heating or cooling.
- Is Pyrex safe to use in the oven? Yes, Pyrex is safe for oven use as it tolerates high temperatures but always avoid rapid temperature shifts to prevent cracking.
- What makes borosilicate glass different from regular glass? Borosilicate glass contains boron trioxide, which increases its thermal resistance and durability compared to regular soda-lime glass.
