The red exhibition hall tells you the difference between building wood burning, electricity burning and gas burning.

? In this year's red exhibition hall firing, it is concluded that wood firing, electric firing and gas firing are three commonly used firing technologies for building lamps. The electric kiln converts electric energy into heat energy to raise the temperature in the kiln. When the temperature in the kiln reaches a certain level, a certain amount of pine is added to create a reducing atmosphere suitable for building lamps in the kiln, resulting in "dust falling"; Gas kilns use gas or natural gas as fuel to increase the temperature in the kiln. Its principle is to adjust the concentration of carbon monoxide in the kiln by controlling the inlet and exhaust holes, and to create a reducing atmosphere suitable for building lamps. Wood kiln is a kiln that uses pine as fuel to raise the temperature in the kiln, and wood (firewood) as fuel should be called "wood kiln". If diesel oil is not as rich as pine wood, the glaze effect of the lamp is not as good as that of pine wood kiln. Firewood kilns can be subdivided into: Tongtianlong kiln, sub-kiln and inverted flame kiln. The temperature control of electric kiln and gas kiln is better than that of wood kiln, which is the mainstream firing method at present. The biggest difference between wood kiln and electric kiln and gas kiln is that the ash and flame produced by pine burning directly run into the kiln, resulting in the phenomenon that natural ash falls on the blank.

From the firing process, electric and gas-fired lamps are like rice cookers, with stable temperature and atmosphere. Burning wood and lighting a lamp is like cooking in a big pot of firewood. In the process of constantly adding firewood, the temperature difference is large and the combustion atmosphere is difficult to control. Because the temperature of wood-burning building lamps is not well controlled and there are differences, it is difficult to control the color of building lamps, showing different color effects, while electric kilns and gas kilns can be controlled at constant temperature through electronic equipment, so the colors are uniform and stable.

Judging from the design and color of glaze, it is only after reduction process that the sword lamp can have exquisite glaze lines. The space of electric kiln and gas kiln is small, the reduction port is specific and the reduction atmosphere is sufficient. In addition, modern temperature control tools assist in stable reduction, so that glaze patterns are far better than Longyao firewood burning. The finished glaze is bright, colorful and colorful. The reducing atmosphere of Longyao wood burning is weaker than that of electric kiln and gas kiln, which makes the glaze color relatively simple, mainly rabbit hair and monochrome glaze, and it is extremely difficult to have exquisite glaze lines, but the finished glaze is naturally moist, rough and powerful, and restrained and simple. In addition, the pores of wood-fired glaze are more than those of electric firing and gas firing, with different sizes and rich layering, while the electric firing and gas firing glazes are basically closed with uniform and dense bubbles.

From the perspective of market acceptance, the appearance of electric and gas lamps has popularized the structure of lamps. Most of the lamps on the market are mainly fired by electricity, because the furnace temperature is well controlled and the glaze pattern is exquisite, which is easy to cultivate colorful light. New lamp lovers tend to choose electric burning and gas burning. Wood-burning lamps have low yield and fewer high-quality products. Playing with firewood lanterns in Longyao is not playing with its colorful light, but playing with its history and culture. Most old lamp lovers will want to start with a wood-burning lamp. After all, wood-burning lamps are closer to history, and they can relate themselves to that distant civilization.

Finally, there is no difference between electric burning, gas burning and wood burning in the selection of building lamps and lanterns. As far as kilns are concerned, they are all tools to realize craftsmen's craftsmanship, and there is no difference between good and bad. Both electric burning and gas burning are products of modern industrial civilization, because different times use different tools. The manufacturing process of sword lamp includes drawing, glazing, decoration and many other processes, and firing is just one of them. The value of a work should not be judged by this, but by more comprehensive and comprehensive standards. Electric and gas burning not only solved the problem of glaze defects caused by ash falling in the firewood kiln, but also greatly improved the yield, got rid of the shackles of saggers, and the architectural lamps had more room to play in size and shape. On the other hand, we can't blindly believe that the works made by wood burning are good, whether it is wood burning, electric burning or gas burning, it is most important to find the right viewing angle.
