A type of glass containing at least 5 wt % boric oxide. It is used in glassware that resists heat and is a leading candidate for use in high-level waste immobilization and disposal.
An optical glass containing boric oxide, along with silica and other ingredients, having relatively high -value and low index of refraction. Some varieties, such as Corning Pyrex® and Schott Tempax®, are resistant to thermal shock.
A strong heat-resistant glass, borosilicate contains a minimum of 5 percent boric oxide, and was first developed by the German glassmaker Otto Schott in the late 1800s. Because of its ability to withstand a wide range of temperature variations, borosilicate glass is the glass of choice for cookware and refrigeration applications. Pyrex is one of the most famous brand names for a borosilicate formulation. At Oceana, we have developed our own, unique formula for this durable glass, which we call “Hard Roc†glass.
A high silicate glass that has at least 5% boron oxide.
A high silicate glass with at least 5% boron oxide.
The addition of borax creates glass resistant to chemical attack and high temperatures
A glass whose main constituents are Silicon Dioxide (SiO2) and Boric Oxide (B2O3). Borosilicate glasses were developed in the early 1920s by Corning Laboratories in response to a need for chemically resistant glassware for laboratory work. It is commonly found in the home today in the form of coffee pots and oven cookware. The properties that make this glass valuable are its extreme resistance to chemicals (even the harshest acids do little damage to the glass or its appearance) and the ability to undergo sudden temperature changes without fracturing.
Borosilicate glass is a particular type of glass, better known under the brand names Pyrex, Kimax, and Endural. It was first developed by German glassmaker Otto Schott in the late 19th century and sold under the brand name "Duran" in 1893. After Corning Glass Works introduced Pyrex in 1915, it became a synonym for borosilicate glass in the English-speaking world.
