2. the process of burning the pottery piece is based on the theory of work on modern pottery technology. From a research study in general the task of the pottery is known at present is that there is a technique of burning a variety of pieces using the stove as the main equipment of thermal power-management control and creativity, which is data from the classification of iron from the characteristics of the. -The type of fuel that originated in the oven, heat gas. The stove uses electricity Stove, firewood and the furnace used oil -Characteristics of the air inside the furnace draft Up Down draft kiln, including kiln, kiln draft Cross.

From the above data, found that the core element of the burning coals in a folk style pottery is only a type of wood as the main raw material for handling matters of heat energy. Best burning technology of pottery in the present matter, regardless of the direction of the air inside the oven is at the heart of the phenomenon of burning as well. Therefore it can infer that there are factors that cause carbon smoke sticks on the surface and becomes an issue leading up to the trial study as follows: 1. technical factors, raw materials 2. factors of deposit of ashes inside furnace 3. factors of air.
