With the clear indication that Pyrex dishes can be safely used in ovens, let’s look at some safety care you should take when cooking with this glassware. You might also be curious about how to identify or use vintage Pyrex dishes if you do happen to come into possession of one. To help give your question more clarity and information, read ahead for what we’ve uncovered in this post.

What is Pyrex?

A type of dishware that is typically made from tempered glass and can withstand high heat, such as being placed in an oven or broiler for cooking food. It is safe for use on the stovetop but should not touch any direct flame. Glass dishes are also not recommended when microwaving foods due to sudden temperature changes (thermal shock).

How do I identify vintage Pyrex? Try looking for the word “pyrex” embossed into the bottom of the dishware, along with numbers near it denoting what year it was manufactured; if you find one without these markings, it is not vintage Pyrex and is likely broken.

Taking care when using Pyrex

There would be nothing worse than hearing the shattering of glass coming from your oven. Picture spending hours prepping a big feast only to have a piece of glassware explode inside, showering your whole meal with thousands of pieces of crushed glass. It can indeed happen when you bake with something like Pyrex, but following specific guidelines and being aware can keep it from happening.

Bring to room temperature

To prevent the glass in Pyrex from shattering, let it come to room temperature before you place it into your oven. If you cook with a dish the day before and store it overnight in the fridge, you can’t just pop it into the oven without letting it sit out first. This protects against thermal shock breaking up the inside of your perfectly prepared meal and setting off an explosion all over dinner.

Check for cracks

Improperly cared for Pyrex dishes may lead to cracks, chips, or other damage as time goes on. Before using the container for your intended purpose, scrutinize it and make sure there are no signs of wear or chip that would compromise its ability to be used in a high-temperature environment. Pyrex can withstand the temperature range of a regular oven. However, if your dish has any cracks or chips, it will shatter into pieces under the intense heat.

Be aware of oven temperature

Pyrex dishes are designed to withstand higher temperatures, but they have their limits. At the lower end of a typical oven’s temperature range, it should be safe for Pyrex cookware to be used inside the oven. Pyrex is safe to use in a conventional or convection oven as long as the temperature does not exceed what is approved for that type of oven.

Keep it off of the stovetop!

Pyrex is secure to use in an oven or microwave because the heat is spread evenly around the glass. However, this type of glassware should not be used on a gas burner because direct heat can cause it to expand and shatter.

TIP: If you’re using your own oven, remember to pre-heat it. And if you are a Pyrex fanatic and have multiple pieces of this glassware in the kitchen, store them carefully, so they don’t knock into one another while clanking around in cabinets or drawers unprotected.

What type of glass is Pyrex?

Pyrex is a tempered glass, which is very different from the window panes that used to be made out of regular plain old glass. Tempered is actually two sheets of clear glass with an inner layer in between them (typically blue or green), and it’s been heated and cooled down until they fused together into one single sheet.
The resulting product is much stronger than traditional dishware because you can’t crack it by dropping something heavy on top of it like you could with typical plate-glass windows. The Pyrex name comes from this new type of strong but lightweight material: “pyro” meaning heat; “Xena” meaning transparent – so Pyrex means “heat-transparent.”

  • In 1998, Pyrex changed its material for dish production – meaning they no longer used borosilicate glass but instead switched over to soda-lime. Here are some more clues:
  • After 1998, there is not always a raised back stamp on their dishes
  • They began using square corners in place of wedges (as seen on Bormioli Rocco products) or round edges (like Anchor Hocking Ware). This can be done with different colors too!
  • Ultimately, vintage Pyrex is the holy grail for collectors. There is a growing market for these pieces because they are so sought after and rare!
