1535538796 AN EXAMINATION OF THE CHANGES ON THE RAW GLAZE COMPOSITIONS AFTER THE ADDITION OF AVANOS AND KINIK CLAYS

Avanos, as a town located in Nevşehir and Kınık village in Pazaryeri, Bilecik, are among the most prominent well-known red clay deposits in Turkey. The common characteristic speci c to these both sites is the fact that the percentage of iron oxide (%Fe2O3) in clays extracted from Avanos and Kınık deposits is above 7 (seven). Within this study, it was aimed to examine the changes and artistic e ects occurring after the red clays from Avanos and Kınık deposits were added to glaze as colorant, in the absence of pure kaolin. Along with this aim, Avanos and Kınık clays were added to raw glaze compo- sitions, and this blend was applied to tablets made through the proportioned mixture of chamotte clay ( reclay), red earth pottery clay and casting clay. In addition to that, pure Avanos kaolin was added at the same amount to raw glaze composition instead of Avanos and Kınık clays and this composition was applied to the tablets as well, produced through the use of same clays in order to obtain com- parative results. Furthermore, additional tests were conducted by adding Avanos and Kınık clays as iron-oxide source to the blend of aventurine glaze, glossy crackle glaze and transparent glaze. Glaze compositions applied to tabled were red at 1050 Celsius degrees, and the e ects were examined carefully in terms of glaze t, compatibility between glaze and clay body, glaze colours, the degree of being matte and glossy and aesthetics. The results indicated that Avanos and Kınık clays, used as the pottery clay in the absence of pure kaolin, could be utilized as substitute of kaolin, and the addition of these clays to glaze compositions lead to small-scale colour changes and artistic e ects.
