Blown Glass/Borosilicate Glass

John Moncrieff Ltd has specialized in offering blown glass solutions to our customers around the world since 1865.

Blown glass is created by the painstaking process of garnering the molten glass at the end of the hollow pipe and is then formed into a decorative molds or vessels by blowing, swinging, and rolling on the iron surface. The glass can be easily manipulated by using the preferred design of the molds and it also depends on the proficiency of the glassmith.
