What is Borosilicate Glass?

Glass is all around us; without out glass, the world as we know it from looking out the window to using your smartphone would be impossible. So what makes borosilicate glass different from normal glass?

Scientific Glass made out of Borosilicate

Borosilicate glass is created by adding boric oxide to a traditional glass mixture(which includes silica, soda, and lime). Adding boric oxide gives the glass a low thermal expansion rate; and this in turn gives borosilicate glass the strength that is known for. A low thermal expansion rate means that borosilicate glass won’t crack when exposed to rapidly changing temperatures; this characteristic is why borosilicate glass is also used to make scientific glass or even cooking ware. Borosilicate glass is 3 times more resistant to temperature change than regular glass.

 

Borosilicate is also glass is more durable than regular glass. If put under a lot of stress borosilicate glass can crack of course; but, it is so durable still that it will not shatter(it will break into chunks).

However, all these wonderful benefits of adding boric oxide come at a price; The price is that borosilicate glass has a much higher melting point than regular glass. Borosilicate glass melts at around 1,500 degrees Fahrenheit while regular glass melts around 1,000 degrees Fahrenheit. In order to achieve these higher temperatures, a special torch that utilizes oxygen alongside propane is used.

Despite the higher cost of production due to the higher costs of raw materials and manufacturing, borosilicate glass is still far more economical in some applications due to its durability. Borosilicate glass can truly stand the test of time and last for generations to come if treated properly. This is among one of the many reason why we choose borosilicate glass to create our art. We want our creations to be timeless for people to cherish so long as they desire.
