One of the fundamental processes of Muranese glasslworks. A very large number of types of applications can be found for this, both functional and decorative. The extreme viscosity of the molten glass allows it to be drawn aot at a certain temperature starting from the end of the blolwer’s pipe in long, narrow pipes. When a layer of coloured glass is superimposed over a base of opaque glass it is possible to obtain numberless variants of colour and thickness in relation to how the molten glass mass is draw out. Suitablyheated rods are used in the decoration of vases and figures. All Murano glass factories have always used them extensively with artistic results that were on occasion quite outstanding, as in the “tessuto” vases designed by Carlo Scarpa.
