It would almost certainly be OK, but to be on the safe side I’d put it on a room temperature baking sheet (ideally quite a thick one) before putting it in the oven. This will avoid the thermal stress caused by the bars of the shelf..

Can I put glass Pyrex in oven?
The short answer to this question is “yes!” Pyrex bakeware (both old and new) is safe to use in your oven – and microwave – as long as you avoid dramatic, sudden temperature changes.
What temperature can Pyrex glass withstand?
High Temps
Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans.
Can Pyrex go in a 450 degree oven?
Pyrex is meant to be able to withstand higher temperatures. But everything has its limitations. Pyrex can be used safely inside an oven that is less than 450 degrees F. Whether or not it’s inside a conventional oven or a convection oven, this glassware will be safe to use so long as that temperature isn’t exceeded.
Is there a difference between Pyrex and Pyrex?
Products with the name ‘pyrex’ (all lowercase) are made by a company called World Kitchen and are made out of clear tempered high-thermal-expansion soda-lime glass, which has a lower thermal shock resistance, making them susceptible to explosions in the microwave or oven.
Can you put cold Pyrex in a hot oven?
Why you can’t put cold Pyrex in the oven. When Pyrex was first created back in 1908, it was made with a special glass (called borosilicate glass) that was thermal shock-resistant. That means that dramatic changes in temperature, like when putting a cold dish into a hot oven, were no match for the sturdy glass.
What temperature does glass break in the oven?
Glass is a poor thermal conductor and rapid changes in temperature (roughly 60°F and greater) may create stress fractures in the glass that may eventually crack. When heated, thin glass begins to crack and typically breaks at 302–392°F.
Can you bake at 350 in a glass pan?
At what temperature can you bake glass? You can indeed bake with glass Pyrex. Pyrex is rated for up to four-hundred and twenty-five degrees Fahrenheit. However, it is not meant to be used on a stove-top or under a broiler, just like any glass dish. If you bake with glass Pyrex at a temperature above 425°F, you run the risk of the glass shattering.
Why did my Pyrex dish exploded in the oven?
When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. If the stress is too extreme, the bowl’s structure will fail, causing a spectacular shattering effect.
How do you stop Pyrex from exploding?
It’s best to put the dish on a dry dish towel or a metal cooling rack to cool. Damp towels or surfaces can also cause the hot glass to shatter. Don’t use tempered-glass bakeware on the stovetop, under the broiler, in a toaster oven, or on a grill.
Will a cold Pyrex crack in the oven?
When using Pyrex or any glass bakeware or cookware, you should avoid extreme temperature changes—very cold dishes shouldn’t be placed in a hot oven, and vice versa. Sudden changes in temperature may cause the dishes to shatter or break.
What is the highest temperature for glass bakeware?
How to Minimize the Risks of Glass Bakeware Shattering
- Avoid changes in temperature; no going from freezer to oven, or from oven to sink.
- Do not add liquid to hot glassware.
- No higher heat than 350 F.
Why is Pyrex called Pyrex?
Company accounts suggest that the name Pyrex came from the company’s tradition of using “ex” in its glass formulas (Corning’s first heat-resistant glass was called Nonex), according to Regan Brumagen, public services librarian and co-curator of the exhibition at the Corning Museum of Glass.
How do you tell the difference between old and new Pyrex? 
Is Anchor Hocking the same as Pyrex? Pyrex and Anchor Hocking use the same glass type for their bakeware and food storage items. The plastic components of containers by both brands are BPA-free. Additionally, the bakeware essentials and containers by both brands are oven, microwave, freezer, and dishwasher-safe.
Can you put Pyrex straight from fridge to oven?
You shouldn’t let your Pyrex go from one extreme temperature to another, whether you’re moving a piping-hot casserole from the oven to the fridge, or a make-ahead cobbler from the fridge to the oven. Instead, let items come to room temperature before adding them to a cold or hot place.
When did Corning stop making Pyrex?
In 1998 however, due to slumping sales and retooling of manufacturing plants, Corning sold off the CorningWare and Pyrex lines to World Kitchen, LLC.
How can you tell Pyrex glass?
Identify Pyrex Using Markings and Stamps
Use the glass markings, stamps, and logos on the pieces themselves to identify when the glass was produced. The oldest Pyrex markings should be on the bottom of glass pieces and feature Pyrex in all capital letters inside a circle with CG for Corning Glassworks.
Which is better CorningWare vs Pyrex?
Essentially, the main difference between Corningware and Pyrex is that Corningware tends to be smaller, and more aesthetically pleasing. No one wants to see grandma’s gorgeously glazed holiday ham in a Pyrex dish; presentation is everything!
What’s the highest temp for Pyrex?
High Temps
Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans.
What temp does Pyrex break?
Is Pyrex glassware susceptible to shattering? Shattering is relatively rare, but it can happen when glassware is exposed to sudden temperature changes (known as thermal shock), extremely high heat (over 425 degrees), or direct heat.
Can Pyrex glass explode?
Pyrex is not resistant to thermal shock, therefore, there are instances where Pyrex glassware can explode when it is moved from a hot environment to a cold one and vice versa. In short, avoid exposing your Pyrex to extreme temperature changes at all times.
What makes Pyrex different from glass? The tempering process when applied to the finished glass products called Pyrex makes it four to six times stronger than the regular glass product. The heat resistant quality to bear up to 425 degrees F makes the Pyrex products ideal for the use in the kitchen especially for cooking or baking purposes.
