<p>A double- or multi-walled thermos container of a ceramic material is produced by moulding of a liquid ceramic mass in a liquid absorbing mould in which a first container (7), which may have a single or several walls, is inserted as a core. The liquid moulding mass is introduced into the space (20) between the inner side (26) of the mould and the first container (7) inserted in the mould. A layer of moulding mass (27) deposits on the inner side of the mould to form the outer wall of the container. After excess of liquid moulding mass has been poured out, the container is removed from the mould and finished by drying, firing and glazing.</p> |
