The Researches and application of the slip glaze which is developed in 1200 C and formed with red clay

m ABSTRACT Throughout the ages, many materials and techniques have been used to strengthen the durability of ceramic pots and to add decorative value. There is a variety of slips and slip compositions which started being used a long time before glaze to decrease the water permeability of ceramics. Slips, which were present in various periods and civilizations, previously had the role of transmitting cultural values. In Greek and Roman ceramics, slips are encountered as a special coating material that embody many technical and artistic elements. The slip composition used in them, and the effect it gives to ceramic pots, is very different. Vitreous and terrasigilata, which is a bright slip type, show similar characteristics to slip. Another type of slip glaze is commonly used in China, Japan and America, and is different from terrasigilata in some aspects. These glazes, which include a high proportion of clay, are natural clays of which shades of yellow-cream-brown can be obtained without using colorings, depending on the texture they yield, the type of clay and the amount of iron they contain In this investigation is defined the slip clay and to present its historical development. Furthermore, this study aims to present the preparation of slip glazes with clays used in various ceramic centers throughout our country. In addition, the aim is also to present different techniques and materials to people who work with ceramics. In order to obtain these results, many tests were carried out with slip glazes.
