A first mould is taken from the original model, and this is used as the base for serial reproduction.

These moulds are held together by a counter-mould known as a "charpa".

The "charpas" are made of paste, burlap and wood, and are used as reinforcement. Normally, 2 "charpas" and 2 moulds are made for each image, and these represent the negative impression of the face and back of the figure (see drawing).

If the figure has complicated parts these are set aside to be added at a later stage. For example, if a figure has a raised arm, extending from the rest of the figure, this piece is usually molded as a separate piece and later fixed onto the figure.

On the "charpa" another mould is made, this time a gelatin-like compound is used, and it is this mould which will be used to make serial reproductions of the figures. Three to nine images can be taken from each mould before it has to be reconstructed.

The gelatin compound is heated in a bain-marie, poured into the mould, and is left to cool until it has solidified to the consistency of soft plastic. The leftover gelatin compound is recycled, a process in keeping with the company's policy of respect for the environment.
