A method for the production of structured caves of stones of artificial stone material

摘要

Mfr. of structured hollow stone from synthetic stone material comprises producing arbitrary shapes from water-holding earths or sands by means of synthetic moulds or sheets and measurements, deep freezing these technically, recasting the earth or sand cores with a liq. stone material or with a plastic paste or binding the cores with the help of the liq. stone material or the plastic paste and recasting, thawing the cores at temps. over 0 deg C and letting the stone material harden or the paste dry, removing the sands from the hollow spaces, and, in the case of the paste, sintering the hollow stones. The structured hollow stones produced by the above process are also claimed.
