Ceramic Slurry - an overview | ScienceDirect Topics

John Campbell, in Complete Casting Handbook (Second Edition), 2015. Shaw Process (Two-Part Block Mould) Shaw process moulds are made by pouring a ceramic slurry into fairly conventional core boxes or patternwork. Thus a cope and drag can be made. The process is described in Section 15.1.3.. The cope and drag technique for mould assembly has advantages in that cores, filters and chills are ...

patterns. In the investment casting process, a ceramic slurry is applied, or 'invested', around a disposable pattern, usually wax, and is allowed to harden to form a disposable casting mold. The wax pattern is 'lost', when it is melted out from the 'disposable' ceramic mold, which is later destroyed to recover the casting.
