The known duplicating flasks have a one-piece, pot-shaped design available in one size only. The new duplicating flask is to have a variable size and a scrap-free, material-saving design. In order to achieve this, the duplicating flask for preparing a female jaw model mould is formed from a base plate (2) carrying a jaw model (1) to be duplicated and a pipe (3) which is inserted therein so as to be releasably fixed in position and which has on its inside annular grooves (4) for anchorage of the duplicating material (5) and, if appropriate, an insert (9) (Fig. 1). The size of the flask can be varied and it permits scrap-free, deformation-proof and material-saving production of the mould. <IMAGE>
