This glass type is part of the family of mouth-blown glasses made with the traditional methods of production. Unlike the other mouth-blown Lamberts-Glasses the balloon is blown to a larger size. It is for this reason that its body is thinner and its surface is smoother and flatter. There is an irregular seediness inside the sheet and the bubbles are oval shaped. The surface structure is open. All the typical features of mouth-blown LambertsGlas® – structure, seediness and movement – are well marked.
The molten gather is first taken from the oven by means of the blowpipe and slowly inflated to the size of a balloon. Due to the size of the balloon this procedure takes place over a deep pit. In the course of the blowing process the balloon is constantly rotated by hand in a mold in order to create a surface structure. After reaching its final size the balloon is cut open at one end and dilated. When the blowpipe has been knocked off, a uniform glass cylinder comes into existence. It is scored lengthwise, reheated, layed open and ironed flat. The result is a finished sheet of glass.
The standard size of the New-Antique-Glasses is approx. 90x105 cm and approx. 2 mm in thickness. Their seediness varies within the sheet and the bubbles are oval shaped. Due to a special annealing process, this glass has good cutting properties and is easily processed. It is produced in clear uncoloured and ten bright tints. Clear New-Antique- Glass is available, in particular, in three stages of seediness: light – medium - strong.
