Restoration-Glasses - Mouth-blown window glass

Original Lamberts-Restoration-Glasses are specially intended for the renovation of old buildings and homes,and the preservation of historic edifices and monuments as well as antique furniture restoration.Until the 1920s almost all window glass was blown.Glashütte Lamberts has retained the production methods of mouth-blown glass in order to guarantee the authenticity of these historically accurate window glasses. Mouth-blown Original Lamberts-Restoration-Glasses therefore part and parcel of any restoration work aimed at meeting the demands of this classical way of glazing. As a matter of fact, the Original Lamberts-Restoration-Glass can also be incorporated into modern insulated window units, thus satisfying the most up-to-date heat and sound protection provisions.

The Production

Restoration-Glass “full” is produced in the same manner as the Clear and Coloured Glasses in the traditional mouth-blown method, whereas the Restoration-Glass “light” is swung over a deep pit during the blowing process. Homogeneous, evenly structured sheet glasses can only be created with the glassblower steadily and smoothly rotating the large red-hot balloon. He must have a good deal of experience, physical strength and craftsmanship.

Technique and Colours

Two types of Restoration-Glasses are available: The “light” type (formerly also called Goetheglas) with an even surface movement is available in sizes of approx. 85x100 cm (33" x 39") and a thickness of approx. 2 mm (3/32").

The “full” type shows a more pronounced surface movement. This type of glass is produced in sizes of approx. 60x90 cm (24" x 36") and is approx. 3 mm (1/8") thick. Glasses of this type are normally clear. However, they can be delivered by request in all the shades of colour available from the LambertsGlas® palette.

Both kinds of glass can be incorporated into modern insulated glass units. Due to the special annealing processes
their cutting properties are excellent. These glasses can be handled easily.

Of course the Original Lamberts-Restoration-Glasses can be used in the most up-to-date insulated glass units which fulfill today’s requirements for heat and noise control.

The ability to produce finished insulated glass units in 10mm thickness, makes installation possible in pre-existing, narrow profile historic windows.
