DECORATION USING THE CLAY CURD TECHNIQUE TO PRODUCE CERAMIC PATTERN
The research sought to study the art of ceramics, its raw materials, techniques and its development. This study included decoration using the clay curd technique and its application to Iraqi clays, as it was concerned with introducing the potter to the mechanism of producing sour clay through the use of local raw materials and how to produce clay curd using primary compounds and raw materials and the mechanism of applying it to red clay Its plastic condition, and two mixtures of clay curds were used to produce curd that is compatible with red clays, and the first mixture was (Iraqi Kaolin, Flint, Soft Croque) which showed unsatisfactory results when the sample dries up and this is what prompted the researcher to find a second mixture (Iraqi Kaolin, Croque, Flint and soda ash) which showed good results after drying, burning and glazing.
As for the theoretical framework, it included a study of an introduction and a historical overview of the use of curd in Iraq, clays and some of their types, ceramic glass and some coloring oxides that were limited to research, and decoration.
The clay curd was prepared and applied as an ornament to the samples and the samples were burned twice at temperatures (950 ° C and 920 ° C). Transparent glass and tinting oxides were added to it and burned again at a temperature of (920 ° C).
The homogeneity of three samples appeared and the lack of separation between the clay curd layer and the ceramic body, and the glazing with colouring added to the samples more aesthetically in terms of appearance, texture and lustre.
