The invention relates to a method for curing cracks in ceramic shaped bodies. According to the inventive method, a filling material which melts at a lower temperature than the material of the shaped body and/or which is flowable at a lower temperature than the material of the latter is applied at least in the area of a crack on the surface of the shaped body and/or is inserted in at least one crack. The shaped body with the applied and/or inserted filling material is subsequently heated up to a temperature at which the material of the shaped body does not yet melt or/and is not yet flowable, however, at which the filling material is at least partially melted on and is in a flowable state. In addition, the filling material is comprised or substantially comprised of non-metallic compounds and is partially crystallized out. The shaped body with the filling material is then cooled.
