Difference between Glass and Pyrex

Whether you’re a pro or just starting out in the kitchen, it’s important to know the difference between glass and Pyrex baking dishes. Though they may look similar, these dishes have different properties that can impact your cooking results. Here’s what you need to know.

What is Glass?

Glass is an inorganic, transparent material that is used in a variety of applications. Glass is made by melting silica sand, soda ash, and limestone at very high temperatures. The molten glass is then cooled and formed into its desired shape. Glass can be either clear or colored, and it can be used to create windows, bottles, and other objects. Glass is also an excellent conductor of heat and electricity, which makes it useful for a variety of industrial applications. Glass is durable and has a long lifespan, making it a popular choice for both commercial and residential use.

What is Pyrex?

Pyrex is a type of glassware that is known for its durability and resistance to thermal shock. It is made from a special type of heat-resistant borosilicate glass, which was first developed in the early 20th century. Pyrex dishes and bakeware are popular kitchen staples because they can be used safely in the oven, microwave, and dishwasher.

In addition, Pyrex is non-porous, making it resistant to staining and easy to clean. Pyrex products are available in a wide range of sizes and shapes, making them perfect for everything from baking pies to roasting vegetables. Whether you’re looking for an essential piece of cookware or a stylish serving dish, Pyrex has you covered.

Difference between Glass and Pyrex

Glass and Pyrex are two types of materials that are often used for cooking and baking. Glass is a brittle material that is made by melting sand. Pyrex is a brand of glass that is made with borosilicate, which makes it more heat resistant. While both materials can be used for cooking and baking, there are some key differences. Glass can shatter if it is subject to sudden temperature changes, whereas Pyrex can withstand temperatures up to 400 degrees Celsius.

Glass also expands when heated, whereas Pyrex expands at a slower rate. As a result, Pyrex is less likely to crack or break when exposed to rapid temperature changes. Finally, Pyrex is typically transparent, while glass can be either transparent or opaque. These properties make Pyrex a better choice for cookware and bakeware than glass.


Glass and Pyrex are two materials that are often confused with one another. They both have their own unique benefits and drawbacks, which we’ve outlined in this post. Hopefully, after reading this article, you now have a better understanding of the difference between glass and Pyrex.
