Procedure
How are the mouthblown Art Deco lamps of Art Deco Trade made? Naturally, they first require the three famous ingredients: sand, soda and limestone. These ingredients are mixed together in an oven at 2300 ºC. This creates thick, liquid glass. When the liquid glass reaches a temperature of 1130 ºC, the glass is taken out of a pot with a steel pipe. A pear wood mould is used to shape glass shades of the lamps. There is a variety of moulds, which can be seen from the diversity of lamps that is offered by Art Deco Trade. The glass that hangs from the tube of the glass blower is formed in the mould. Air is blown through the pipe which makes the liquid glass grow. While rotating the pipe, the glass takes on the form of the mould. Then the glass lampshade is separated from the pipe, and placed into an oven. Here the object is cooled for approximately 24 hours so that it will not crack under thermal tress. Finally, the neck is sawed off at the right height and is polished so the lamp has a nice finish.
Handmade products
Since the lamps are made by hand and are mouth-blown, small ‘imperfections’ can occur in glass lampshades, such as small air bubbles. This occurrence is part of the natural process of glass blowing and turns the lamp into a unique and traditionally-made product.
