One of the questions people ask is “is borosilicate glass lead free”? It is important to know the kind of material you use for drinking as it will be of good health benefit for your wellbeing. Read below and find valuable information regarding lead-free glasses.


After much research, I finally found the answer to the question, what is borosilicate glass? Borosilicate glass is not like every other type of glass. It’s a special glass that is made of two chemicals: boron trioxide and silica.

Borosilicate glass is also known for having a very low thermal expansion coefficient which makes them have a higher resistance to thermal shock than other traditional glasses.

The chemicals used in producing borosilicate glass cookware, bakeware, or drinking glasses are safe, environmentally friendly, making it very heat resistant than other types and forms of glass available on the market.

Furthermore, Borosilicate glasses are used for the construction of high beverage glassware, laboratory equipment, flasks, reagent bottles, electronics, lighting, and cookware.

Just like every other glass, borosilicate is safe to drink from because it is BPA-free itself. This glass is not like plastic that pollutes the environment. It improves sustainability and keeps plastic waste out of landfills.

Finally, Borosilicate glass is sold under various names; Duran, Pyrex, Simax, Kimax, Borosil, Suprax, Bellco, and Marinex. Etc.


Borosilicate glass is very safe and safer than plastic and soda-lime glass. This glass does not contain any harmful toxins, nor will it leach harmful substances into your food or drink.

The absence of BPA also makes borosilicate safe. When BPA is ingested, it creates serious health problems, especially for babies and children.

Borosilicate is also safe because it resists acid degradation and chemicals. When you eat or drink from this glass, your food or drink tastes better because the material does not leach out as it does in other BPA-containing packaging or plastic.
