NATURAL MATERIALS TO CREATE A RELIEF GLAZED SURFACE ON PRODUCTS OF CERAMIC MASS

Abstract

The article discusses the features of stone ceramics decorating with natural materials (various grains and several types of flowers were used to obtain a decorative relief on the ceramic surface), which allows to obtain glazed surfaces with an unglazed concave relief, creating the effect of the graffito technique. The dependence of the relief index on the shape of the impression and decorative effects are shown. It has been experimentally revealed that in the depressions obtained by pressing large flowers, there is a coating of the core of the imprint with glaze, with not deep prints – a distribution in the form of droplets. As a result of using legumes and some types of flowers, the concave relief is covered with a transparent glaze and optically perceived as convex. According to the method of assessing the nature of the relief, the quality of the decorated surface was determined. The systematisation of the decorative effects of the glazed surface is carried out, tak-ing into account the relief and the influence of the material and shape of the impression on the glazed surface.
