Glass Selection

 

From its inception, traditional stained glass has been made using hand made, mouth blown glass that deliberately includes numerous flaws, bubbles, striations and distortions.  It is just these imperfections that give a window that compelling sparkle and movement that flawless machine made glass can never achieve.  The colour of the glass is determined by different metal oxides that are included in the batch before the glass is heated in a furnace until molten and for this reason is referred to as the pot colour.

Mouth-blown glass is called ‘antique’ glass due to its close resemblance to the medieval glass of the great European cathedrals and to make a sheet of antique glass requires great skill and teamwork.  A master glass blower gathers a gob of molten glass on the end of a blow pipe and proceeds to blow a very large cylinder of glass which then has each end cut off.  The open ended cylinder is split down one side and then placed in a kiln where it is heated to softening point and then opened up to form a flat sheet.
