Utensils made of Pyrex glass can be used for heating. It is a low-thermal-expansion borosilicate glass used for kitchenware. It is a non-metal.
Can you put Pyrex in recycling?
While pyrex ovenware is a type of glass – it has been specially treated in the manufacturing process to withstand high temperatures, which makes it non-recyclable. If you have broken or chipped pyrex ovenware to get rid of, do not recycle it with other glass items. Simply dispose of it carefully in your rubbish bin.
What is Pyrex made of?
Pyrex bowls were originally made of something called borosilicate glass, which is very resistant to thermal shock. Currently, Pyrex is made of soda-lime glass, presumably as a cost-cutting measure, as soda-lime glass is very inexpensive.
Why is Pyrex special?
Pyrex pieces used to be made of borosilicate glass, which is more resistant to breakage when subjected to extreme shifts in temperature. Although tempered glass can better withstand thermal shock than regular soda-lime glass can, it’s not as resilient to such stress as borosilicate.
Why Pyrex Cannot be recycled?
Although Pyrex is made of glass, it can’t be recycled because it’s been chemically treated to withstand high temperatures, which changes the composition of the glass.
What can I do with old Pyrex?
Pyrex and other heat-treated bakeware and kitchen glass cannot be recycled, so if it’s no longer useful in the kitchen, throw it in the trash, or repurpose it. Why Isn’t Heat-Resistant Glass Recyclable? Glass is melted down in the recycling process.
What’s so special about Pyrex?
In a glass composition, this extra strength gives it thermal and chemical resistance that makes it useful for cooking applications, thermometers, and laboratory equipment. Pyrex also has a low alkali content that gives it high corrosion resistance.
Is vintage Pyrex dangerous?
Is vintage Pyrex safe to use? The short answer to this is “I wouldn’t use it.” This was a common response to the test posted on Facebook. People insisted that since food doesn’t come in contact with the outside of the bowls, these tests do nothing more than drum up fear.
What is the rarest Pyrex?

What kind of glass is not recyclable?
A: Unfortunately broken window glass (and drinking glasses, plates, mirrors) are not recyclable in our program. These types of glass have a different melting temperature than beverage and food glass containers. Please wrap non-beverage and food glass in newspaper or plastic bags and place in your garbage can.
Is Pyrex a good brand?
Pyrex is great quality, very durable, does not stain and is great for many uses in the kitchen and for families. I love the versatility of the bowls for cooking, storing, and reheating and they do not break easily.
How do I know if my Pyrex is worth money?
Identify Pyrex Using Markings and Stamps The color and pattern isn’t the only thing that will help you determine whether your Pyrex is antique or vintage. Use the glass markings, stamps, and logos on the pieces themselves to identify when the glass was produced.
How is Pyrex glass different from regular glass?
The difference between glass and pyrex is that pyrex is more strong, fire-proof, which means that it can withstand greater temperature fluctuations and shatterproof as well when compared to normal glasses which cannot handle such temperature fluctuations.
How do you dispose of tempered glass?
Get a few sheets of newspaper and wrap larger pieces of glass into papered layers. Tie the newspaper with pieces of string and place inside a large plastic bag. Do not throw away with the normal house trash but take it to a recycling center instead.
Is kimax the same as Pyrex?
Kimax is also known as KG-33, and is a low expansion borosilicate glass. It is very similar to Pyrex, having the same chemical and physical properties.
Is Pyrex glass heat resistant?
Pyrex is borosilicate glass which makes it highly temperature resistant.
Which type of glass is heat resistant?
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass.
What are the properties of Pyrex glass?
Chemically, Pyrex contains borosilicate and expands only about one-third as much as common glass (silicate) when heated. As a result, it is less apt to break when subjected to rapid temperature changes. It is resistant to many chemicals and is an electrical insulator.
What is a Pyrex drug?
It turns out that Pyrex has become a popular slang term because the tempered glass can be used to cook crack cocaine. You might’ve already noticed that if you browse #pyrex on Instagram, it’s a mix of pretty vintage housewares and drug paraphernalia.
Is Pyrex good for the environment?
Windows and Pyrex bakeware are not recyclable because of the way it’s manufactured to withstand high temperatures. Last but not least, glass takes one million years to decompose in the environment, perhaps even more in a landfill. In total, that’s about four major problems with glass that impact the environment.
Can I pour boiling water into Pyrex?
Can you pour boiling water into Pyrex? So, Pyrex… is bog standard borosilicate glass. However, no glass is immune to catastrophic failure due to thermal shock, and I advise that you stop putting actual boiling water into Pyrex glasses. Pyrex actually breaks quite easily under thermal attacks if it’s done just right.
Is Pyrex cheaper than glass?
Soda-lime glass is cheaper to make than borosilicate glass, which is undoubtedly why Pyrex started experimenting with it. Resistance to thermal shock is part of why Pyrex became so popular for cookware; you could move a hot glass pan into a cool spot without worrying about it cracking or shattering.
