The invention relates to a method for the hot shaping of molten gobs on a mold base by interposing a gas bed, comprising the following method steps. According to the invention such a method comprises the following method steps: a mold base made of open-pore mold material is produced; the supporting surface of the mold base is coated permanently with a glass contact material; such a coating material is chosen or the coating is arranged in such a way that the layer comprises open pores after its application which allow a gas-conductive connection between the lower side and the upper side of the layer; the mold base is charged with a gas in order to produce a gas bed on the upper side of the layer.
