Jianzhan, how to distinguish between traditional ancient firewood burning and modern firing technology?

A: Basically, from these three points. 1. Due to the continuous addition of firewood in the firing process, the temperature rises and falls, which shows that the bubbles are different in size and have a certain sense of layering, while the bubbles are uniform and dense in modern gas firing and electric firing;

2. Because the temperature of the floor lamp burning firewood is difficult to control, there are differences, so the color of the floor lamp is difficult to control, showing the effect of dark and light colors, while the gas kiln can be controlled at constant temperature, so the burning color is stable;

3. The ash and flame of wood burning easily run into the kiln, forming natural ash and falling on the green body, and fusing with glaze at high temperature for a long time to form a layered warm color.
