Food Storage Pureglas

• Wash with mild detergent, rinse and dry
• Delicate cycle in the dishwasher on the top rack
• Do not stack containers without lids on
• Do not use over direct flame
• Remove the plastic lid when using in oven, microwave oven and dishwasher
• Do not heat empty containers
• Do not carry the container by holding just the lid as it could fall off

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.

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. 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.

Plastic water bottles are terrible for 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.

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.

Borosilicate glass can resist chemicals and acid degradation, you don’t need to worry about stuff seeping into your water or food. It’s always safe to drink and eat from. You can put it in the dishwasher, put it in the microwave, use it to store hot liquids or 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, something very common in plastic water bottles or less expensive stainless steel alternatives.

Drinking and eating from plastic bottles/containers can have a metallic flavour taste over time. This occurs because it is actually seeping into your water due to the solubility of the plastic and steel. This is both harmful to your health and unpleasant.

When using borosilicate glass the liquid inside remains pure, and because borosilicate glass has low solubility, it keeps your beverage free from contamination.

Borosilicate glass is made by adding boric oxide to the glass mixture. This process creates a type of glass that is more resistant to thermal shock than ordinary glass. It isn’t completely unbreakable, but it is sturdier than regular soda-lime glass.

No, Borosilicate glass will break if it is directly in touch with a heat source such as a gas flame. However, Borosilicate glasses can go in the oven as the max temperature is 400C.

Moreover, the heat source is also indirect and is from 3 sides. So they work best in the oven baking. Gas flames have a temperature from 1200 – 1500 °C, so the glass can break if heat is only from one side and is direct.
