Pyrex is made from borosilicate glass, which is designed to withstand high temperatures. However, it's crucial to understand that while Pyrex can handle high heat, it's not indestructible. The maximum recommended temperature for Pyrex is 425°F (220°C). So, what happens when you use Pyrex at 450°F?

When Pyrex is heated to 450°F, it's approaching its thermal shock limit. Thermal shock occurs when a sudden change in temperature causes the glass to expand or contract rapidly, leading to cracking or shattering. While Pyrex is designed to resist thermal shock, using it at 450°F increases the risk of this happening.

Here are a few things to consider when using Pyrex at 450°F:

  • Preheating: Preheating your Pyrex dish in a cool oven before increasing the temperature can help distribute heat more evenly and reduce the risk of thermal shock.
  • Sudden Temperature Changes: Avoid placing a cold Pyrex dish into a preheated oven or exposing it to sudden temperature changes, as this can cause cracking.
  • Even Heating: Ensure your oven heats evenly to prevent hot spots that could cause your Pyrex dish to crack.

Pyrex vs Other Bakeware Materials

While Pyrex can handle high temperatures, other bakeware materials have their own temperature limits. For instance, aluminum and stainless steel can withstand higher temperatures than Pyrex, but they may not distribute heat as evenly. Ceramic and stoneware dishes can also handle high temperatures, but they may not be as durable as Pyrex.
