Can pyrex go from freezer to oven?

In this brief guide, we are going to answer the question “Can pyrex go from freezer to oven?”   with an in-depth analysis of baking in pyrex dishes and its alternatives? Moreover, we are going to discuss the composition of pyrex glass.

Can pyrex go from freezer to oven?

If your Pyrex glassware is old, it has been made before 1998 then it can go from freezer to oven.

Because this pyrex is made of borosilicate glass and is thermal-shock resistant.

However, if your Pyrex glassware has been made after 1998, then moving it from freezer to oven is not a good idea.

Because this pyrex doesn’t have thermal shock resistance and cannot bear the temperature fluctuations.

Can you bake in a pyrex dish?

Yes! You can bake your pasta, casserole, and even cakes in the pyrex dish.

But it should be done with greater attention and care.

Because if you miss handled it, the pyrex dish can break into pieces and you would have a lot of cleanups to do.

But no shattering of pyrex dishes happens if pyrex dishes have been made before 1998 because those dishes were thermal shock resistant.

What can be the cause of the breakdown of pyrex dishes in baking?

Following are reasons that can result in the shattering of pyrex dishes in baking if it’s mishandled.

  • Uneven heating
  • Direct exposure to heating 

elements

  • Extreme temperature fluctuations

How to use pyrex dishes safely?

Follow the instructions given below to use pyrex dishes safely;

  • Always keep the pyrex dish in a preheated oven to protect it from any heat shock or temperature fluctuations.
  • Always avoid putting the refrigerated dishes directly into the oven.
  • When you get refrigerated pyrex dishes, first let them reach a temperature equal to room temperature.
  • You cannot put the pyrex dish on the stovetop.
  • Also never keep the heated pyrex dish from the oven into the refrigerator.
  • Oven mitts can be used to handle the hot pyrex dishes but don’t use them wet 
  • Never keep an empty Pyrex dish in the oven.

What is the temperature tolerance of pyrex glass?

Pyrex dishes made by using borosilicate glass are adapted to stand greater temperature fluctuations.

Because they are heat-shock resistant.

These pyrex glasses can easily tolerate the heat-shock of 170 degrees.

Pyrex can bear features as low as 446°C and up to 914 degrees Fahrenheit.

But always be careful when the temperature hits 450 degrees celsius because it can cause heat shock and break the pyrex dish.

When do pyrex dishes shatter?

Pyrex dishes undergo shattering when the temperature exceeds their capacity to withstand.

The heat shock expands the glass and then it relaxes.

In this process,  the glass loses its structure and undergoes shattering into pieces.

Borosilicate pyrex glass is the most suitable for baking because it has boric acid in its composition which makes it heat resistant.

What are the alternatives to the pyrex dishes?

Following are the alternatives to the pyrex dishes;

Cast iron:

  • You can use cast iron as an alternative to the pyrex sheet in baking cakes,  pizza and pancakes etc.
  • It can safely be used as well as on the stovetop.
  • Also, iron is very effective in evenly baking your dishes.

Ceramic:

  • Another alternative to the pyrex dishes is ceramic.
  • It works similarly to last but it is better looking as compared to glass.
  • Also, it is very easy to clean.

Metal pans:

  • You can also use metal pans as an alternative to the glass pyrex.
  • Lighted color metal pans impart a brown color to your crust.
  • You can use the darker coloured metal pans to give your crust darker colors.
  • You can use aluminum among metals as it evenly bakes the food as compared to stainless steel.
  • But baking acidic or spicy food, use of aluminum plates should be avoided because aluminum can leach into food which is harmful to health.

What are the uses of pyrex?

Pyrex is a type of glass that is commonly used kitchen also and is resistant to heat and chemical and is used  in making;

  • chemical apparatus
  • industrial equipment,  including piping and thermometers, and ovenware.

What is the composition of Pyrex glass?

According to the National Institute of Standards and Technology, borosilicate Pyrex is composed of the following things; 

  • 4.0% boron
  • 54.0% oxygen
  • 2.8% sodium
  • 1.1% aluminum
  • 37.7% silicon
  • 0.3% potassium

Here are the advantages and disadvantages of using pyrex.
