The word "pyrex" is correctly spelled with the stress on the second syllable, as /ˈpaɪrɛks/ (pie-reks). This is a trademarked brand name of a type of heat-resistant glassware that is frequently found in kitchens. The word "pyrex" is derived from the Greek word "pyr," meaning fire, and "ex," meaning outsider. This is appropriate for glassware that is designed to withstand high temperatures. However, it is important to note that the term "pyrex" is often used incorrectly to refer to any type of heat-resistant glassware, regardless of the actual brand name.
Pyrex is a trademarked brand of clear borosilicate glass created by the Corning Glass Works company. It refers to a specific type of high-quality glassware, known for its durability, heat resistance, and translucency.
Pyrex is widely used in cooking, baking, and food preparation because of its ability to withstand high temperatures. It is resistant to thermal shock, which means it can go from extreme hot to cold temperatures (or vice versa) without shattering. This makes Pyrex an ideal material for ovenware, such as baking dishes, casserole dishes, and pie plates.
The borosilicate glass used in Pyrex is also non-reactive and non-porous, meaning it does not absorb flavors, odors, or stains from food. This makes it hygienic and easy to clean, as it can be safely washed in the dishwasher. Additionally, the clear glass allows for easy visibility, which is especially useful for monitoring food while cooking or baking.
Originally introduced in 1915, Pyrex has become a household name for high-quality glassware. It has been trusted by generations of cooks and chefs for its reliability, versatility, and longevity. Today, the term "Pyrex" is sometimes used generically to refer to any glassware used for cooking, even if it is not made by the Corning Glass Works company.
The word "Pyrex" comes from the combination of two elements: "pyr" and "ex".
The term "pyr" is derived from the Greek word "πῦρ" (pronounced 'pür'), meaning fire. It signifies the heat resistance of the material.
The element "ex" in this context refers to a type of glass called "borosilicate glass". Borosilicate glass is a type of glass with high thermal resistance, meaning it can withstand extreme temperature changes without shattering. "Ex" is an abbreviation of "experimental", indicating that Pyrex was a new and experimental type of glass when it was first introduced.
Combining these two elements, the term "Pyrex" highlights the heat-resistant nature of the glass, making it suitable for various applications, including cooking and laboratory equipment.
