Linings sintered with ash effect in wood furnace at 1200 oC

With the discovery of the plastic property of clay by man, various ceramic pots have begun to be produced. These containers have been used for different purposes such as food consumption and storage and are also produced in different forms. Various primers have been used to prevent the permeability on the surfaces of these containers they produce. The engobe, which was discovered since the beginning of the Neolithic Age in the B.C. in the 8000's, began to be used for decoration purposes in various colors, usually the color of clay itself, black and red. The engobe, which were diversified in color over time, were fired with different firing techniques. In addition to these different techniques, dullness, brightness and color changes occur on the primer surface by using different raw materials in the primer. The thesis study on "Engobe Sintered with Ash Effect in Wood Furnace at 1200oC", which has been prepared, consists of five chapters. With this study, it is aimed to provide resources that can help those who want to work with high grade engobe by documenting the linings that have been tried in high grade wood kiln. In the first part, the definition, history and historical development of ceramic engobe are mentioned. In the second part, the raw materials used in the production of high-grade ceramic liners, the coloring oxides and their properties, the materials in the structure of high-grade ceramic bodies such as chamotte, stoneware, porcelain used in engobe applications, their production stages, properties, colors and grades are explained. In the fourth chapter, the artists who worked with their own recipes and styles in various wood-fired furnaces and the liners they worked with were mentioned and examples were given. In the fifth chapter, the construction stages of wood-fired main, noborigama, soda and salt furnaces, the materials used in their construction, their purpose of use, how many chambers they are formed, how many degrees they are raised, and the stages of placing the ceramics in the furnace, closing the furnace, burning and unloading the furnace are explained. Also, in the chapter, the results of fired in a wood oven by applying the colored engobe, which I have obtained successful results as a result of my researches and experiments, from the engobe that have been experimented on firewood and porcelain body at 1200oC in a wood ash furnace, on forms made by hand shaping on mud lathe, are examined.
