What are the applications of Borosilicate Glass?

Borosilicate glass is a type of glass in which the major glass-forming ingredients are silica and boron trioxide. Because of their low coefficients of thermal expansion, borosilicate glasses are more resistant to thermal shock than any other common glass. Such glass is subjected to minimal thermal stress and is able to sustain higher temperature differences of up to 165 °C (297 °F) without shattering or breaking. It’s often used to make reagent bottles and flasks, as well as lighting, electronics, and cookery.

“What are the applications of Borosilicate Glass?”

Ablaze Glass Works is a noted and distinct borosilicate glass manufacturer in Vadodara, Gujarat.


When Otto Schott began experimenting with glass compositions, the primary difficulty he was seeking to solve was to design a glass that could withstand excessive temperature exposure. In rainy situations, for example, the glass used in lanterns would shatter or crack because the cold rain on the external surface of the glass creates a high-temperature difference when contrasted to the temperature of the hot interior face.

When borosilicate glass was first made available, its possibilities were obvious. The following are some of the most common applications for borosilicate glass:

1.  Laboratory glassware:

Because of its excellent dimensional stability and ability to withstand multiple temperature changes at the same time, borosilicate glass is a natural choice for laboratory glassware, often known as labware. Common examples include flasks, microscope slides, test tubes, petri dishes, beakers, bottles, funnels, and measurement tools such as graduated cylinders. Aside from its excellent thermal qualities, borosilicate glass is chemically resistant and non-reactive.

If you are looking for the leading supplier of top quality borosilicate glass reactors in Vadodara, Ablaze Glass Works is the right choice for you.

2.  Scientific lenses:

As per your requirements, you can mould the borosilicate glass into high-precision optical components like telescope lenses and many other precision optical devices. Because borosilicate glass has a low coefficient of thermal expansion, the optical properties of the lenses will remain stable when the temperature changes because the glass lens’ dimensions will not vary considerably. The glass is also suitable for use in infrared-reflecting hot mirrors.

3.  Cookware:

The manufacture of home cookware and bakeware is one of its first and most widespread applications. Borosilicate cookware’s thermal qualities allow it to be moved from a hot oven to a cool tabletop without cracking or fracturing. It’s also found in items like measuring cups, and it’s safe to use in microwaves and dishwashers.

4.  Thermal insulation:

Thermal tiles made of borosilicate glass were employed to shelter the space shuttle from the heat of reentry into the atmosphere.

Ablaze Glass Works is one of the most prominent and reputed borosilicate glass manufacturers in India.

5.  Heavy-duty lighting products:

Because stage lights and lighting goods used in the film business can achieve high temperatures when operated continuously for hours on end, borosilicate glass lenses are used. borosilicate lenses or outer envelopes will be used in other lamp products that utilise high-intensity discharge (HID), such as mercury vapour lamps or metal halide lamps.

6.  Sight glass:

Tanks in industrial processes employ sight glasses, which are frequently made of borosilicate glass. These glasses provide visual monitoring of substances and processes without having to open the tank or storage vessel or disrupting the process.

7.  Aircraft exterior lenses:

Because of its clear optical qualities (transmissibility) and ability to survive the temperature differential observed during high altitude flight, borosilicate glass lenses are used in aircraft external lighting.

8.  Aquarium heaters:

Borosilicate glass is commonly used in aquarium heaters, as the heater tube is exposed to a thermal gradient between the internal nichrome heating element and the tank’s much colder water.

9.  Rapid prototyping:

Borosilicate glass is an appropriate material for use in fused deposition modelling, a type of 3D printing or additive manufacturing, where heated and extruded plastic ingredients are deposited throughout the build process.
