Islamic Glass art, especially in Egypt and Syria, seems to have evolved from ancient traditions somewhat more continuously than in the West, although there is little evidence that Glass was particularly prized in the early Islamic period. As in Christianity, burial Objects are not used in Islam, a fact that makes it considerably more difficult to draw conclusions about Glass art and its early development. That said, some Glass Objects themselves demonstrate their makers’ great skill in Glassblowing. Here, the colourless and blue Glass were fused with great precision following extensive shaping when hot in using the ‘incalmo’ technique, which later became known in relation to Murano Glass. This technique presupposes an established tradition of quality Glassmaking. It is primarily thanks to the donations of Helmut Hentrich that Middle Eastern Glass is a key focal point of Glasmuseum Hentrich. The collection is among the most important in Europe.
