Date Apr. 30, 1981.A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.
