How to Ensure Pyrex Won’t Shatter Inside the Oven The plastic lid of the dish is for storage and microwave use only. It is not intended for commercial and industrial purposes–not even for camping. If you bought a regular Pyrex dish, it is designed only for kitchen use. It can be used for warming, cooking, reheating, and baking food in preheated standard and convection ovens, including microwave ovens. The customer service staff followed his statement by saying that as long as the safety guidelines are followed, particularly the ones that come with the product, Pyrex can withstand 400☏.

In response to a customer’s question, the company’s consumer care department replied that the glassware has no maximum temperature so long as you preheat the oven before putting it inside. Pyrex is a kitchen glassware brand with remarkable heat capacity. Pyrex can also be used in preheated standard and convection ovens. The Pyrex Use & Care guidelines state that Pyrex glassware can be used for warming, cooking, baking, and reheating food in microwave ovens. Read on to learn more about Pyrex glassware and how to safely use it in the oven. This causes uneven heating on the bottom of the Pyrex, which can cause the Pyrex to fracture. If your Pyrex is in the fridge or freezer, allow it to come to room temperature before you put it in the oven.Īlso, never use Pyrex glassware on top of the oven, e.g., on ceramic or induction cooktops or burners. So avoid sudden temperature changes when using your Pyrex. The main cause of Pyrex shattering in the oven is if the dish is moved straight from the fridge or freezer into the oven. The maximum temperature Pyrex is designed to withstand is up to 914☏. Pyrex dishes are safe to use at a temperature of 446☏. The Pyrex Use & Care guidelines state that Pyrex glassware can be used for warming, cooking, baking, and reheating food in microwave ovens as well as preheated standard and convection ovens.

But a question many people have is how well Pyrex holds up in the oven? Is Pyrex oven-safe? MEGHANN MARCOĮditor's Note: This article originally appeared on Consumerist.Pyrex kitchen glassware is popular because it is durable and strong. Pyrex, in its current incarnation, should be treated more like any other piece of glass. Do not change its temperature rapidly, regardless of what the website says. Since Pyrex is no longer made of the same special thermal shock resistant glass, one should take extra care when using it. Glassware products can go directly from refrigerator or freezer to a microwave, convection, or preheated conventional oven.” The Pyrex website makes no mention of a change in materials, and does not specify what type of glass is used in their products. Also, Pyrex is no longer made by the original manufacturer, and is essentially a brand name, rather than a material. Currently, Pyrex is made of soda-lime glass, presumably as a cost-cutting measure, as soda-lime glass is very inexpensive. Pyrex bowls were originally made of something called borosilicate glass, which is very resistant to thermal shock. Taking a bowl directly from the freezer and putting it into a hot oven might also trigger breakage. Stove tops and broilers conduct heat quickly, and will likely cause the bowls to fail. The main way to avoid this effect is to be mindful of how quickly you change the temperature of Pyrex. If the stress is too extreme, the bowl’s structure will fail, causing a spectacular shattering effect. When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. The text book definition of thermal shock is: “Stress produced in a body or in a material as a result of undergoing a sudden change in temperature.” When glass changes temperature rapidly it can undergo “thermal shock.” In fact, there’s no mention of “shattering Pyrex” on their website at all. And, of course, this probably has to do with the fact that Pyrex isn’t going to advertise “may shatter” as a feature of their product. A reader wrote in because he set his Pyrex bowl on the stove top to reduce some broth, and the bowl promptly “exploded.” It appears, through googling (and You Tubing), that a great many people do not realize that Pyrex bowls have a tendency to shatter violently and dramatically when placed on a stove top or otherwise heated/cooled rapidly.
