Abstract
A process for artificially ageing blocks, in particular concrete blocks, vitrified bricks and natural stones, provides that the blocks are applied to an underlying surface. Essentially freely movable distressing bodies are applied to the surface to be worked of the blocks. The blocks and the distressing bodies are brought into movement in relation to one another by a vibrating motion of the underlying surface in such a way that the distressing bodies act on the surface and the adjoining, exposed edges of the blocks.
