Purple sand pot Chai kiln and electric kiln gas kiln which is good?

Which of the purple clay pot and electric kiln gas kiln is good, this debate has lasted for many years. Some people think that the purple clay pot of Chai kiln is better, unique, and is a traditional firing method; While others think that the electric kiln gas kiln is a new improved firing method, more stable, and the quality of the fired pot is better.

Purple sand pot Chai kiln and electric kiln gas kiln which is good?

There is no clear answer to which firing method is better. Because different firing methods have their own advantages, but also have disadvantages.

For example, the advantages of kiln firing are that each pot produced is different and unique, but the disadvantages are also clear, because the temperature is not easy to control, so the yield is very low and the price is relatively high. And some parts may be fired, the temperature may be too high or too low, resulting in the overall quality is unstable.

The electric kiln and gas kiln can accurately control the temperature with a computer, the yield is high, and the color after firing is unified, but the disadvantage is that it is identical, every one looks similar, lacks characteristics, and is easy to aesthetic fatigue.

1, different stomata: the temperature of wood burning is not uniform, the temperature is sometimes high and sometimes low, the need to keep adding wood to control the temperature, so that the stomata will not be unified, some large and some small; The electric firing is different, because the temperature is stable, the formed pores are more unified, and very uniform.

2, the color is different: the temperature control of the wood burning is not good, and because the flame is always changing, the heat of the pot is not uniform, some places are high, some places are low, resulting in the color of the wood burning pot is not uniform, some places are dark and some places are light; The heat in each direction of the electric fired purple clay pot is uniform, so the color is very uniform after firing, regardless of the color of the part is unified.

3, wood burning ash phenomenon: wood burning wood (pine, bamboo, all kinds of wood, etc.) combustion of the ash and flame should be followed into the kiln, the natural ash phenomenon on the body, after a long time of high temperature fusion into a natural gray glaze, its color warm, rich layers, texture rough and strong, with the general gorgeous bright glaze is different, will not repeat and it is difficult to expect the results of the kiln.
