Blown Glass
John Moncrieff Ltd has specialized in offering blown glass solutions since 1865.
In simple terms Blown Glass is created by gathering the gob of molten glass on the end of the hollow pipe. The the gob of glass is then presented to the pre-heated mould and blown to the required shape. This creates a raw-blown glass item. After cutting, finishing and annealing, you have your final item.

Borosilicate Glass
We can offer blown glass in borosilicate glass which has an excellent heat and chemical resisting properties. It is principally used for scientific and engineering applications. Blown borosilicate glass can be used for domestic use such as glass shades. The main advantage of using borosilicate glass is that it can be blown very thin, offerring a very light wall thickness.
Quartz Glass
Quartz glass is where the clarity or the ability to resist great heat up to 1200°C is a requirement. This comes in flat sheets or tubular form. It can be manipulated into various forms or cut into your required shape, but it has more limitations than with other glass types.
Opal Glass
We use opal glass, triplex opal and flashed opal glass for a wide range of blown glass lighting applications. Opal glass is an excellent diffuser of light. Our capacity can blow opal glass to a maximum of 600mm. It is also available in flat and tubular glass.
