Pâte de verre (literally translated means glass paste) dates back to the ancient Egyptians, but it really came into its own about a century ago when it was revived by a group of French artists who gave this warm glass technique its current name. In traditional French pate de verre, the artist blows object before incorporating crushed glass with enamels between two or more layers of glass. When the lamp is completed, it is placed in an oven and is cooled gradually during several hours.
