Introduction

Borosilicate glass 3.3 is specified as a standard glass - it contains mainly sand, calcium carbonate and sodium carbonate.

High quality sand, dehydrated borate boric acid, alumina and salt are used in its manufacture and strict control is applied to ensure the specifications for purity and consistency of these materials are maintained. Because of its resistance to heat, corrosion and thermal shock borosilicate glass 3.3 is used extensively in science and in industry.
