An attractive mid 20th Century pate de verre glass study of butterfly rested on a rose with excellent detail and very fine vibrant colour, signed Daum France Daum Glass Pâte de Verre is a rare and ancient glassmaking technique, which dates back to 5000 bc (pieces have been found in the tombs of pharaohs). In 1900 Daum rediscovered this technique that had been long forgotten, then further developed it in 1968. The process of melting glass coupled with the lost wax technique that Daum has developed, ensures a perfect reproduction of the original piece just as the artist had imagined it. Today, Daum is the only glass maker in the world able to produce this exceptional material so perfectly. Pâte de Verre is a mutable substance, which has translated every whim of the imagination of the master glassmakers for over a century, in this way, no two pieces are identical, because the fragments of groisil blend and merge at will as the glass melts. This mastery and constant research have resulted in world renowned masterpieces. Date of Manufacture circa 1980.
