Pyrex is also known as borosilicate glass.
It consists primarily of Silica and boron oxide.
According to Wikipedia, typical borosilicate glass is composed of:
70% silica (silicone dioxide SiO2), 10% boron oxide, 8% sodium oxide, 8% potassium oxide, and 1% calcium oxide (lime).
Wikipedia does note that some kitchenware glass marketed as Pyrex is actually soda lime glass.

What else can I help you with?
What element makes Pyrex glass?
Borosilicate glass is the primary element in Pyrex glass, which contains a higher proportion of boron trioxide than traditional soda-lime glass. This composition gives Pyrex glass its unique thermal properties, making it more resistant to temperature changes and suitable for use in cooking and laboratory applications.
What year did they change the pyrex glass formula?
Pyrex changed its glass formula in 1998 from borosilicate to tempered soda-lime glass.
Is pyrex plastic?
Pyrex glass is designed to withstand sudden & drastic TEMPERATURE changes. Most glass will shatter with sudden temperature changes. Pyrex is not bulletproof. Most transparent bulletproof material (glass) is composed of several layers of plastic & glass sandwiched together. The plastic holds the glass together, while the glass absorbs a bullet's impact.
Is the Bunsen burner made of pyrex?
No, a Bunsen burner is typically made of metal, specifically brass or stainless steel. Pyrex is a type of borosilicate glass that is commonly used for laboratory glassware such as beakers and test tubes.
What chemical will harm pyrex pipe?
Hydrofluoric acid is a chemical that can harm Pyrex glass due to its ability to etch or corrode the glass surface. Pyrex glass is quite resilient to most chemicals, but strong acids like hydrofluoric acid can cause damage.

Is All glass made from Pyrex?
No, not all glass is made from Pyrex. Pyrex is a brand name for a type of borosilicate glass that is known for its durability and resistance to thermal shock. There are many other types of glass with different compositions and properties used for various applications.
What is a pyrex?
Pyrex is anothe anme fore borosilicate. They are names for glass which are heat resistance and are used in laboratories.
Which type of glass is the cheapest Soda glass Pyrex glass or Silica?
I would have to say Pyrex
What is a pyrex beaker?
Pyrex is anothe anme fore borosilicate. They are names for glass which are heat resistance and are used in laboratories.
How does pyrex dishes works?
Pyrex dishes are made of a special glass that can withstand high heat without shattering. The unique composition of Pyrex allows it to expand and contract evenly, making it ideal for baking and cooking. This type of glass is also nonporous, so it does not retain odors or flavors from previous use.
Does pyrex hold on to caustic chemicals?
Pyrex is borosilicate glass and like all glass does not absorb any chemicals.
What year did they change the pyrex glass formula?
Pyrex changed its glass formula in 1998 from borosilicate to tempered soda-lime glass.
Can you use Pyrex glass bowls in a convection oven?
Yes, Pyrex can be used in the microwave as well as conventional oven.
Is pyrex plastic?
Pyrex glass is designed to withstand sudden & drastic TEMPERATURE changes. Most glass will shatter with sudden temperature changes. Pyrex is not bulletproof. Most transparent bulletproof material (glass) is composed of several layers of plastic & glass sandwiched together. The plastic holds the glass together, while the glass absorbs a bullet's impact.
Why pyrex or borosil glass is used in testubes?
Because they make the glass less likely to break during extremes in temperature.
What is pyrex glassware?
Pyrex is just a brand name of toughened, heat-resistant glass.
