A liquid or pasty mixture of substances is at least partially solidified by cooling the mixture between two interspaced surfaces which can be tempered and have varying temperatures. The mixture is cooled such that an ordered structure emerges during the solidification process. Afterwards, the product which is at least partially solidified is freeze-dried. As a result, especially homogeneous porous structures emerge which have a significant importance in the fields of medicine and cosmetics.
