The article proves that the stepped pattern can be a versatile tool in examinations of casting quality, i.e. in determination of dimensional accuracy and surface microgeometry. Moreover, the pattern may be useful in evaluation of some important technological parameters used by investment casting technology, e.g. in evaluation of the anisotropy of the ceramic mould properties, which considerably affects errors of the dimensional deformation [...] at successive stages of the technological process of making ceramic moulds and investment castings. The results of the measurements of investment castings made in mixtures of the ceramic materials, like SiO2 and aluminosilicates – Molochite bonded with silicate binders, like colloidal silica, ethyl silicate, SIKOP [1], EKOSIL [2], were evaluated.
