The crackled or craquelé surface effect differentiates mouth-blown Crackled-Glass from the Original Clear and Coloured Glasses. Its fissured and cracked surface is similar to that of crocodile skin.


The balloon-shaped red-hot ball of glass is briefly plunged into cold water after blowing. The tiny cracks appearing on the surface are caused by the temperature shock. The Crackled-Glass is then reheated to close the tiny cracks. Small crisp-edged spots on the surface are attributable to the process.

Technique and Colours

Crackled-Glass is usually produced in bright tints to show the texture to its full advantage. But almost all the shades of the extensive Lamberts colour palette are available. The size of a sheet is approx. 60x90 cm (24" x 36"), the thickness is approx. 3 mm (1/8"). All the sheets are delivered with their edges still intact. Small variations in the dimensions occur due to the handmade production of the individual sheets.

Fields of Application

Sheets of Crackled-Glass are often incorporated into door- and window-panes to let light pass through while preventing inquisitive eyes from disturbing people’s privacy. The glasses can also be used as furniture panels.
