[Experimental study of new embedding materials suitable for the casting of non-precious metal alloys].

: In everyday practice hitherto used embedding masses permitted so to say but the making of shrinked castings. On basis of experiments performed with embedding masses (Bellavest, Castorit C) prepared for precious-metal-free alloys recently marketed it has been ascertained that exact castings can be prepared from moulds embedded therein if technical discipline is observed.
