The different techniques of glass globes

The glass globe has become an essential element of lamp design since the 18th century. Over time, numerous manufacturing techniques have been developed to create elegant and timeless designs. In this article, we will explore the different glass manufacturing techniques for lighting fixtures from the 1700s to the 1980s.

Mouth Blowing

Mouth blowing is one of the oldest manufacturing techniques for lighting glass. This technique involves heating the glass to a high temperature and blowing air through a tube to form a desired shape. The designs achieved by this technique are often unique, as they are hand-blown by an artisan. This technique was popular from the 18th century until the invention of the glass blowing machine in the 19th century.

Moulding

Moulding is a manufacturing technique that involves pouring molten glass into a mould. This technique is used to create more uniform designs than mouth blowing. The moulds can be made of metal, wood, or plaster. This technique was widely used in the 19th century to produce mass-produced designs, especially for chandeliers.

Engraving

Engraving is a technique for decorating lighting glass that involves etching patterns onto the surface of the glass. This technique has been used since the 19th century to create elaborate and sophisticated designs on lamp glasses and shades. The patterns can be floral, geometric, or abstract, and are often hand-engraved.

Gilding

Gilding is a decorating technique that involves applying a thin layer of gold to the surface of the glass. This technique has been used since the 18th century to add a touch of luxury to glass lighting designs. Gilding can be applied to all or part of the glass to create elegant patterns.

Fire Drawing

Fire drawing is a manufacturing technique that involves stretching molten glass into thin threads. These threads are then braided or wrapped to create complex designs. This technique was used in the 19th century to create decorative glass pieces for lamps, including serpent-shaped pieces.

In conclusion, lighting glass has been manufactured using numerous techniques over the centuries. Mouth blowing, moulding, engraving, gilding, and fire drawing are some of the most common techniques used to create elegant and timeless glass lighting designs. Artisans continue to work with these techniques today, adding their own personal touch to create innovative designs that continue to captivate the eye and the imagination.
