Can Pyrex glass utensils be used Safely In The Oven Without Breaking?

Pyrex glass utensils are absolutely safe to use in the oven. Many users are confused about the safety and use of glassware utensils in the kitchen, especially the oven for fear of breakage or exploding glass.

However, breakage or damage is unlikely to occur if the manufacturer’s instructions on the particular utensil, especially Pyrex glassware, is followed accurately and in detail. To avoid any sort of damage or injury, precautions should be taken not to allow scratching or cracking of the glassware and also do well to store in a safe area.

Not only that Pyrex glass utensils are oven-safe, but they are also dishwasher safe, microwave-safe and still suitable for freezing. Try not to place a pyrex glass on a direct heat source, such as a gas or electric stovetop, in order for you to enjoy it for a long time. A pyrex dish can be placed directly into the oven, microwave and the refrigerator without any issues.

What Is A Pyrex glass?

Pyrex glass is a tempered glass used for most cooking wares. It is a brand introduced by coring Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. Pyrex glass products are made up of borosilicate which composes of (as a percentage of weight): 4.0% boron, 54.0% oxygen, 2.8% sodium, 1.1% aluminium, 37.1% silicon and 0.3 potassium.

These brand of glasses are easy to clean and handle: and their nonporous construction resists stains and odours. Pyrex glasses that are used to produce cookware and bakeware are available in a range of sizes and styles, including casserole dishes with fitted lids for storage. The glass is very durable and resistant to chips and cracks but it can shatter if dropped onto a hard surface.

Improvements

Beginning from 1980, the production of Pyrex glass shifted from the use of borosilicate to soda-lime glass which has a higher mechanic strength than that of the borosilicate, however, it has a lower thermal shock resistance than borosilicate Pyrex.

Due to its high temperature-resistant nature and resistance to scratching and high mechanical strength, Pyrex glassware has been used safely in a whole range of application from laboratory glassware to kitchen utensils.

Is Pyrex glass bowls oven-proof?

Most Pyrex glass bowls usually have a symbol at the bottom of the bowl to indicate whether it is oven-safe or not. Nevertheless, Pyrex glass bowls are specifically made to be used in the oven and can withstand oven temperatures. Hence, they are completely safe to use in as much that sudden change of temperature from hot to cold is avoided (thermal shock) and proper care and handling is observed.

The Different Types Of Pyrex Glass Utensils

There is a wide range of Pyrex glass utensils all used for various purposes and shapes. From glass bowls and plates to glass straws, spoons, sticks, measuring jugs etc.

The utensils vary according to their intended use from oven-baking to the heating of food; glass beakers for measurement in the laboratory or kitchen glassware or mugs.

And they are usually chosen for their resistance to heat and physical damages and we can definitely see why.

Is pyrex glass still as durable as it used to be?

There has been a lot of speculation recently about the durability of Pyrex glass today compared to the past. However, it is correct to say that Pyrex glass is still as durable and safe to use as ever before, even though the durability might be affected by when it was produced.

If your pyrex was produced before 1998, it was made with borosilicate materials which have high thermal shock resistance. After 1998, pyrex began to use soda-lime silicate glass instead of borosilicate. This switch of materials increases the mechanical strength of the glassware significantly according to the manufacturer but more susceptible to thermal shocking. While any glassware has a risk of breakage, Pyrex glassware has an exceptional safety record.

How To Safely Use A Pyrex Glass

Using glasses, in general, comes with some precautions one have to consider following so that their utensils don’t get damaged before long. For a pyrex glass which you want to use very often especially in the oven, a little extra care can go a long way in ensuring the lifespan of the glass is longer. Here are a few tips to help:

  1. You can ensure safety measures by pre-heating the oven before use to avoid uneven temperature and thermal shocking. In this case, thermal shock can cause the glass to expand and contract, causing the glass to shatter if the temperature change is extreme enough. This can be easily avoided when care is taken to avoid a sudden change of temperature of the glassware for example from hot to cold temperature and vice-versa
  2. Have it in mind too that it’s better to not hold a wet cloth to hot glassware and also avoid putting hot glassware in cold liquids immediately.
  3. If you turn off the oven, wait a few minutes for it to cool down before opening it to bring out the glassware. Remember that bringing it out from a hot temperature to a cold one almost immediately can cause damage.
  4. Being careful not to expose the glassware to other heat sources is an extra measure for safety.
  5. All Pyrex glassware is made to be safely used in the oven. Hence it is safe to use for oven purposes and shouldn’t bother you much. The oven must be preheated before inserting the glassware though.
  6. Avoid sudden temperature changes to glassware. DO NOT add liquid to hot glassware; place hot glassware on a wet or cool surface, directly on countertop or metal surface, or in the sink. Allow hot glassware to cool on a cooling rack, potholder or dry cloth. Be sure to allow hot glassware to cool as provided above before washing, baking, refrigerating or freezing.
  7. DO NOT use on or under a flame or other direct heat source, including on a stovetop, under a broiler, on a grill or in a toaster.
  8. Add a small amount of liquid which is sufficient to cover the bottom of the dish prior to cooking foods that may release liquid.
  9. Avoid handling hot glassware (including ware with silicone gripping surfaces) without dry potholders
  10. Avoid too much microwave/oven misuse, especially when not necessary.
  11. Try not to use glassware to microwave popcorn or foods wrapped in heat-concentrating material (such as special browning wrappers), heat empty or nearly empty glassware in microwave, or overheat oil or butter in microwave (which can use a minimum amount of cooking time).
  12. Handling your glassware without an appropriate degree of care could result in breakage, chipping, cracking or severe scratching. DO NOT use or repair any glassware that is chipped, cracked or severely scratched.
  13. DO NOT drop or hit glassware against a hard object or strike utensils against it to test their strength.

  1. […] For heating foods, they are not harmful. Foods that are heated/cooked in a microwave are quite safe and would give you the same nutrient value as cooking on other heat sources. People say that heating foods in the microwave can cause cancer; there is no proven research that shows a link between the use of microwave and the development of cancer in the body. However, I would recommend that you try to avoid microwaving your foods in plastic plates as some of them are not safe and may cause chemicals to leak into your food. This is because heat can cause the BPA and Phthalates in your plastic container to leak into your food; these components are far from healthy for your skin. It’s better to heat/cook your foods in the microwave using a good microwave-safe glass or container. […]
