Hi there! Chef Ken here, at your service. I've spent decades in the kitchen, experimenting with countless recipes and techniques, and I've learned a thing or two about cookware along the way. People often wonder: "Can Pyrex go from the freezer to the oven?" Well, let's dive into the history of Pyrex and clear up some common misconceptions.

The name Pyrex often evokes images of our grandmothers' kitchens, filled with sturdy, dependable glass baking dishes. And for good reason! Original Pyrex, introduced in 1915 by Corning, was made from borosilicate glass, a type of glass known for its exceptional durability and resistance to thermal shock. This meant you could safely transfer a dish made of this material from a hot oven to a cold countertop without fear of it shattering. It revolutionized baking!

However, things changed. In the late 1990s, the Pyrex brand was sold, and the new manufacturer switched to using soda-lime glass for their bakeware. While more cost-effective, soda-lime glass doesn't possess the same thermal shock resistance as borosilicate glass. It's important to note that the packaging still says "safe for oven, microwave, and freezer," but the reality is a bit more nuanced.

Here's the deal: while the newer Pyrex bakeware is technically freezer and oven safe, the drastic temperature change can cause stress and increase the risk of breakage. It's like constantly stretching a rubber band; eventually, it's going to snap.

So, to answer your question directly, yes, you can technically put Pyrex from the freezer to the oven, but I strongly advise against it. The risk of breakage is significantly higher with the newer soda-lime glass composition.

**Here are some additional tips for using your Pyrex safely and effectively:**

* Always preheat your oven gradually. Don't subject your Pyrex to sudden, extreme temperature shifts.
* **Avoid placing a frozen Pyrex dish directly into a hot oven or vice versa.** Allow it to come to room temperature first.
* **Never place a hot Pyrex dish on a cold or wet surface.** This sudden temperature change can be too much for the glass to handle.
* **Inspect your Pyrex for any chips, cracks, or scratches.** Even small imperfections can weaken the glass and make it more susceptible to breakage.

Remember, while Pyrex is a versatile and convenient kitchen staple, it's not indestructible. By following these simple guidelines, you can help prolong the life of your Pyrex bakeware and enjoy its use for years to come!

Happy baking!
