What is high borosilicate glass?
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 resistant to thermal shock, more so than any other common glass.
Why is borosilicate glass food container better?
Borosilicate glass is much more resistant to thermal shock. Borosilicate glass has a very low CTE (Coefficient of Thermal Expansion) whereas soda lime glass has a very high CTE. It's for this reason that all quality cookware is made from borosilicate glass.
Is borosilicate glass container safe for drinking?
It's better for you. Since borosilicate glass resists chemicals and acid degradation, you don't need to worry about stuff seeping into your water. It's always safe to drinkfrom. You can put it in the dishwasher, put it in the microwave, use it to store hot liquids or leave it out in the sun.
Is borosilicate glass container BPA free?
While Borosilicate is far more durable and resistant to thermal shock than other types of glass, it is glass so breakage is still a possibility. ... Borosilicate glass is hypoallergenic, lead-free and unlike a plastic straw, it is BPA-free.
Is borosilicate glass food container safe or toxic?
Borosilicate glass food container has a melting point of 1648 C, so nothing will happen to its composition when heated to a mere 210 C.
Borosilicate glass was first developed by the German glassmaker Otto Schott in the late 19th century. Otto Schott was also the founder of today's Schott AG, which has sold borosilicate glass later under the brand name DURAN. As part of an equity carve-out in 2005, the DURAN Group was founded and the manufacture of Duran was transferred to it. After Corning Glass Works introduced Pyrex in 1915, the name became synonymous for borosilicate glass in the English-speaking world (though, in reality, a sizable portion of the glass produced under the Pyrex brand has also been made of soda-lime glass since the 1940's). However, borosilicate glass is the name of a glass family with various members tailored to completely different purposes. Most common today is borosilicate 3.3 glass such as Duran, International Cookware's NIPRO BSA 60, and BSC 51.
In addition to quartz, sodium carbonate, and aluminium oxide traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass. The composition of low-expansion borosilicate glass, such as those laboratory glasses mentioned above, is approximately 80% silica, 13% boric oxide, 4% sodium oxide and 2–3% aluminium oxide. Though more difficult to make than traditional glass due to the high melting temperature required, it is economical to produce. Its superior durability, chemical and heat resistance finds use in chemical laboratory equipment, cookware(glass food container, glass jars, glass baking dish), lighting, and in certain kinds of windows.

Temperature Range & Structural Integrity due to Low Thermal Expansion
Borosilicate glass’ strong resistance to temperature makes it desirable in chemical and pharmaceutical processes. The maximum permissible operating temperature for QVF borosilicate glass is 200°C (due to limiting factors such as PTFE gaskets). Above a temperature of 525°C the glass begins to soften and above a temperature of 860°C it changes to the liquid state. Conversely, it can be cooled down to the maximum possible negative temperature, but is generally recommended for use down to – 80°C. An additional benefit within temperature allowance is the ability for borosilicate glass to be exposed to two different temperatures at the same time (though for safety reasons it is recommended that temperature difference does not exceed 100 K).
