A common misconception is that all glass is the same. The limitations of one, relay the limitations of another but that is simply not the case.

A special category of glass that defies the boundaries of the most common glass types is “Borosilicate Glass”. The most notable difference lies in its durability, most notably its thermal shock resistance. In other words, this glass has the ability to withstand extreme temperatures without cracking or shattering unlike ordinary glass.

Although this may seem magical, there is a worldly explanation to why this type of glass is so different from the rest:

Borosilicate GlassSoda-Lime Glass
80% Silicon Dioxide
Lessens susceptibility to fractures
69% Silicon Dioxide
Lessens susceptibility to fractures
15% Boron Trioxide
Increases thermal shock resistance
15% Sodium Oxide
Increases melting point & creates yellows tint
5% Sodium & Aluminum Oxide
Increases silica melting point & flexability
9% Calcium Oxide
Improves chemical resistance & durability

So now you know the worldly reasons for why this glass is so unlike its competitors, but what does this mean for consumers like you? Why should you care? Well…

1) Borosilcate glass withstands a much wider range of temperatures -- goes from the freezer to the oven with ease.
2) Borosilate glass expands by half the amount as Soda-Lime glass when exposed to heat -- noticeably less risk of shattering, fracturing, or cracking.
3) Borosilcate glass is more flexible and has greater optical clarity than other glass types -- no more chipping or yellowing from everyday use.

Although searching for the best type of glass may not have been on your to-do list for the week, now that you are here it may be time to take a closer look into the materials that play such a large role in your kitchen.

 Switch to borosilicate today, to ensure that everything you cook tomorrow is prepped, served, and stored in the finest glass possible.
