What is a Borosilicate glass?
It is the same kind of glass used in laboratories due to its superior strength, durability and ability to resist thermal shock, making it extra safe for your little one. Borosilicate glass is also much lighter than traditional glass that is used for baby bottles, and is microwave, dishwasher and sterilizer safe. Our Borosilicate glass bottle is 100% non-toxic, BPA, PVC, Lead and Phthalate free. The thermal insulation tiles in the space shuttle are coated with a borosilicate glass.
