Pyrex Glass

Pyrex glass was introduced in 1915 by Corning Incorporated and is designed as a thermal shock resistant range of glassware products. Originally only made from borosilicate glass Pyrex is now made from two different types of glass, the aforementioned borosilicate glass for laboratory applications and also soda lime glass, for some kitchen glassware.

Borosilicate glass was first used by Corning Incorporated in 1912 in railroad signal lanterns for the American Railway Company. James Littleton of Corning, adapted the glass to make a baking tray which when tested withstood the heat of the oven. This was how the first kitchen glassware was developed and it sold three years later.

Today the Pyrex range not only has over one hundred heat resistant glassware products but is also made up of microwavable and non-stick products.

Pyrex is heat resistance up to 300°C and allows you to use it safely in the oven and micro-wave. The non porous and stain resistant features are designed to keep the glass hygienic and transparent for a long time. However, Pyrex is not designed to be used in direct contact with heat from a flame or an oven hob as this will damage the glass.

As well as being able to withstand very high temperatures, Pyrex can also be used in the freezer.
