Abstract
The properties and soundness of the cast part produced by investment casting vastly depend on the properties of the ceramic shell which is made by investing layers of slurry and various stuccoes in investment casting. The shell should possess enough strength to withstand the weight of the molten metal being poured while being sufficiently permeable to expel out gases produced inside the cavity while the metal is poured. Hence this paper initially reviews the ideal slurry composition for ceramic moulds prepared for aluminium castings. Later, the factors which govern the strength and permeability of the shell are discussed
