What is Borosilicate Glass?

Our BIBS Baby Glass Bottle is made of borosilicate glass. But what does that mean? And why is borosilicate glass that much better than regular glass? Read on if you want to know why we are so very excited about this type of glass and why we chose to use borosilicate glass for our baby bottle.

What is Borosilicate Glass?

Borosilicate glass contains ‘boron trioxide’ alongside the traditional mixture of glass ingredients. This makes borosilicate glass more durable and resistant than other forms of glass.

Advantages of Borosilicate Glass

  • Temperature- and thermal shock resistant

Borosilicate glass can endure quick temperature changes, and therefore exhibits high resistance to thermal shock. (Thermal shock is cracking because of rapid temperature change). The glass withstands freezing, microwave heating, and boiling temperatures. Borosilicate glass can go straight from a freezer to an oven without cracking. This means that you can pour boiling water into your baby bottle if you want to sanitize it, without worrying about shattering or cracking the glass, as regular glass would.

Borosilicate can withstand temperatures of up to around 170°C. This characteristic makes borosilicate glass a popular glass for baby bottles (like ours), glass cookware, lab equipment, and premium wine glasses.

  • Durable

Borosilicate glass is more durable and harder than regular glass, and therefore harder to break. It holds up against harder drops and impacts than regular glass. Note: that borosilicate glass is still glass and can of course break if subjected to sufficiently intense force.

Further, borosilicate glass will not change shape over time, discolor or fade.

  • Shatter resistant

If borosilicate glass does break it tends to crack into bigger chunks rather than shatter into small pieces. This means that it is safer and easier to clean up, and you avoid the dangerous tiny pieces of shattered razor-sharp glass all over your house.

  • Chemical and acid degradation resistant

Borosilicate glass resists chemicals and acid degradation. It is therefore safe to drink from, and you don’t need to worry about stuff seeping into your water (or in the case of our baby bottle – the milk). You do not have to worry about the bottle heating up and releasing harmful toxins into the liquid.

  • Safe and food-grade

Borosilicate glass is completely non-toxic, and as a parent, you never have to worry about chemicals leaching into their baby’s food and drinks.
