Abstract
A method of forming a slip cast article is disclosed. The slip cast article is formed in a casting volume of a forming mold which has a portion thereof formed of a dissolvable organic material which has binder properties. A casting slip is cast into the casting volume. The vehicle of the casting slip is drawn off to a level which provides a consolidated casting in the casting volume containing sufficient vehicle that the casting is resistant to shrinkage. The consolidated casting and the organic mold portion are placed in a solvent for the mold portion so that it may be dissolved. The solvent for the mold portion is one which is miscible with the vehicle of the casting slip. The consolidated casting is maintained in the solvent after the organic mold portion has been dissolved so that the dissolved organic material previously forming the mold portion may penetrate into the consolidated casting. The consolidated casting is removed from the solvent and dried so that the organic material which penetrated into the casting will remain behind in the porous structure of the casting to lend strength thereto as a binder material.
