Why Borosilicate Glass Is Superior To Normal Glass
WHAT IS BOROSILICATE GLASS?
Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries.
Not all glass is created equally.
Borosilicate glass is made up of about 15% boron trioxide, which is that magical ingredient that completely changes the behaviour of glass and makes it thermal shock resistant. This allows the glass to resist extreme changes in temperature and is measured by the “Coefficient of Thermal Expansion,” the rate at which the glass expands when it is exposed to heat. Thanks to this, borosilicate glass has the ability to go straight from a freezer to an oven rack without cracking.
In terms of temperature, the maximum thermal shock range (the difference in temperatures it can withstand) of borosilicate glass is 170°C, which is about 340° Fahrenheit.
The boron in the glass makes it less soluble, preventing any unwanted materials from leaching into the glass, or the other way around. In terms of overall performance, borosilicate glass is far superior to regular glass.
WHAT’S THE DIFFERENCE BETWEEN BOROSILICATE GLASS AND SODA-LIME GLASS?
Many companies choose to use soda-lime glass for their glass products because it is less expensive and readily available. It accounts for 90% of manufactured glass worldwide and is used for items like furniture, vases, beverage glasses and windows. Soda lime glass is susceptible to shock and does not handle extreme changes in heat. It’s chemical composition is 69% silica (silicone dioxide), 15% soda (sodium oxide) and 9% lime (calcium oxide). This is where the name soda-lime glass comes from. It is relatively durable at only normal temperatures.
BOROSILICATE GLASS IS SUPERIOR
The table above shows Borosilicate glass has a much higher proportion of silicon dioxide in comparison to regular soda lime glass (80% vs. 69%), which makes it even less susceptible to fractures. The coefficient of soda-lime glass is more than double that of borosilicate glass, meaning it expands more than twice as fast when exposed to heat and will break very quickly.
WHAT IS BOROSILICATE GLASS USED FOR?
Because of its durability and resistance to chemical changes, borosilicate glass has traditionally been used in chemistry labs and industrial settings, as well as for kitchenware and premium wine glasses because of it’s superior quality.
SHOULD I SWITCH TO A BOROSILICATE GLASS BOTTLE?
Your body will thank you. Since borosilicate glass resists chemicals and acid degradation, you don’t need to worry about chemicals seeping into your water. It's always safe to drink from. You can put it in the dishwasher, can leave it out in the sun. You won’t have to concern yourself with the bottle heating up and releasing harmful toxins into the liquid you are drinking.
The environment will thank you. Since borosilicate glass is made from naturally abundant materials that are more easily acquired than oil, the environmental impact is also smaller. If handled with care, borosilicate glass will last a lifetime. Plastic water bottles harmful you the environment . They are made from petroleum, and they almost always end up in either a landfill, lake or ocean. Only 9% of all plastic gets recycled. Even then, often times the process of breaking down and reusing plastics leaves a heavy carbon footprint.
