Porcelain blanks in various gaseous medium heat, its sintering temperature, eventually firing shrinkage, shrinkage rate and stomatal rates are not the same, it should be constituted under the blank mineral chemistry, different iron, titanium oxide content, and choose a different atmosphere system. Southern District multi-use porcelain restore the flame burning system, that a small fire oxidation, reduction fires; use more whole area north of porcelain oxidation flame burning.

Develop institutional atmosphere, the gas should also have a correct understanding of the nature of the medium. In general, the nature of the gaseous medium is based on the content of free oxygen in the combustion products and the reducing component to the decision, when the kiln gas having oxidizing ability, which the excess air coefficient is greater than 1, the free oxygen content of 4 to 5%, called common oxidizing flame; when free oxygen content of 8 to 10%, it is called a strong oxidizing flame; when the oxygen content of 1 to 1.5%, and the kiln gases have no oxidizing reducing power, which the excess air ratio is equal to 1, called neutral flame; and when the content of free oxygen in the 0 to 1%, the kiln gas having reducing ability which the excess air coefficient is less than 1, known as reducing flame.

For reducing flame firing ceramics, as far as possible so that the percentage of O2 concentration less than l% or close to zero, the excess air ratio should be less than 1, the concentration of CO can be composed of 2 to 7% of control in accordance with blanks.

For oxidizing flame firing ceramics,  values porcelain stage should be controlled at 1.2 to 1.7. When heavy oil as fuel,  value should be 1.1 to 1.3, with bituminous coal as fuel when,  value of 1.3 to 1.7, with gas as fuels,  is 1.05 to 1.15; preheating zone summary smoke flue the  value of 3 to 5.
