Investigations on utilisation of reclaimed materials from used ceramic moulds applied in the investment casting technology, are presented in the hereby paper. This reclaim was used as a matrix for the preparation of the test moulds. Rheological properties as well as tensile strength at a room temperature of such ceramic sands were even better than of sands made of fresh components. However, ceramic sands with a reclaimed material exhibited worse properties at higher temperatures. The second direction of utilizing the reclaim was using it as the so-called powder topping when making ceramic moulds (for the II^nd and successive layers). Tensile strength values at high temperatures of moulds made with the reclaim participation were comparable (and in some cases even higher) to values of moulds made of fresh components (Al₂O₃). These results encourage the further investigations in this field.
