Our glass bottles are manufactured in Type I glass, which is known as borosilicate glass or neutral glass.
They are guaranteed BPA free and without risk of migration (phtalates, sulphide). Borosilicate glass has a low coefficient of expansion which strengthens its resistance to thermal and mechanical shock. Compared to soda-lime glass, borosilicate glass has a much higher resistance.
It is the ideal glass for baby bottles and pharmaceutical bottle which are experiencing changes of temperature when being heated up in a microwave. Unlike plastic botlles, borosilicate glass bottles are sterilizable and can be washed infinitley.
