To the untrained person, watching an experienced Cairns Local Glass glazier make a scratch on a piece of glass and then have the glass drop into two pieces in his hands, is a bit like watching a magician. These experienced glaziers can casually run a line down a piece of glass, cut around into a long curve and with a quick flick of the wrist, have the glass drop into exactly the design required, safely and with no apparent effort at all.

Understanding Glass types
The subject of glass is quite extensive and it is an amazing substance, however we will just talk about the types that you are likely to come across in your project.
Annealed (Plate) Glass
Most glass is produced as “annealed” glass. Also known as “plate” glass, “sheet” glass and other local names. When glass is in this state, it breaks into large chunks and slivers with razor sharp edges.
Main uses are in residential windows, aquariums, shop fittings and some shop fronts, and is easily cut as we will demonstrate soon.
The first common treatment for annealed glass is to laminate it to another piece of the same thickness.
It is common to laminate that is, join together, 2 by 3mm pieces to get a thickness of 6.38mm (the extra .38 being the plastic interlayer).
The strength of this glass product is slightly less than the same thickness of a single thickness, but as it will not break into threatening pieces, it is considered a Grade A safety glass.
