The invention relates to a process for the preparation of a fixed blow-moulding mould or a casting mould, preferably for glass. The process according to the invention is characterized in that materials suitable for making the mould are mixed with water in such a way that a mouldable mass is obtained, which is shaped to obtain the required moulds, and the resulting moulds are frozen to solidify them. In addition to the water needed for the moulding and freezing to obtain a solid object, the fixed blow-moulding or the casting mould also consists of at least a cellulose fibre material and/or ashes or a material compatible therewith. |
