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

  • Excellent temperature and thermal shock properties

Borosilicate can endure high heat (up to 450 °C) while also having excellent thermal shock resistance. This means that you can sanitize it without worrying about cracking the glass.

You can also use the bottle for freezing. The guaranteed temperature difference is 100°C when properly handling the bottle. When using it in a freezer, we recommend not to put it directly into a microwave but to let it defrost first.

  • 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.

  • 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.
