restauro® - Genuine Window Glass Genuine Lamberts Restoration Glass is specially crafted traditional window glass to meet the requirements for renovation of old buildings, the preservation of historical monuments and restoration of antique furniture. Until the early 20th century, all window-glass used to be manufactured by gaffers with blowpipes. Glashütte Lamberts has preserved these production techniques and provides the authentic charakter of historic window-glasses until today. Mouthblown original Lamberts Restoration Glass is an indispensable part of every glazing restoration, that requires the original air of historic windows. The former name of "restauro® - Restorationglass® is Goetheglass" 'Goetheglass' is a mouth blown window glass. It has a light movement and occasional bubbles. The name comes from its use in the 'Goethehaus' (birth house of Johann Wolfgang von Goethe) in Frankfurt. www.lamberts.de
