Type I glass consists of various elements, all of which are great at resisting chemicals of strong acids and alkalis. It is made up of 80%silica, 10% of boric oxide, and small quantities of both sodium oxide and aluminium oxide. All type I glass containers are suitable for both parenteral and non-parenteral preparations.

This is a type of glass container that contains 80% silica, 10% boric oxide, small amount of sodium oxide and aluminium oxide. It is chemically inert and possess high hydrolytic resistant due to the presence of boric oxide. It has the lowest coefficient of expansion and so has high thermal shock properties.
