How to light the building lamp How to light the building lamp

1. The raw material of Jianzheng embryo is raw ore soil near the kiln site. Because of its high iron content, it shows the characteristics of "iron embryo" after firing. The advantage of using raw ore soil as blank can maximize the overall appearance of Jianzhan and the characteristics of kiln mouth. However, the mud washing screen should generally not be too thin, so as not to affect the simple and rugged beauty of Jianzhan.

2. The basic raw material for glaze selection is the raw ore glaze stone used for kiln building in Song Dynasty, plus local red clay and plant ash in Jianyang, which are filtered for later use. It is worth noting that even if the local raw ore glaze is selected as the basic glaze, the influence of different factors such as different ore occurrences and materials should be considered.

3. Generally, you need to draw blanks by hand, dry them and burn them. When glazing, it is full of glaze inside and half glaze outside, and the concentration and thickness of glaze water remain uniform. Some people think that glazing twice is beneficial to the formation of firing stripes, but in fact, these glazing times do not affect the quality of stripes.

4. The lanterns are divided into wood burning and electric burning. The former is difficult to grasp the temperature and time, but the lanterns are more antique. Electric burning improves the success rate and product quality, and makes many marks that it is difficult to burn with firewood, which is beneficial to environmental protection and cost saving.

5. The firing temperature of Jianzhan can be controlled above 65438 0300℃. For example, if the temperature is too high, the oil droplets will easily melt into pieces, the glaze will stick to the bottom, and the cup blank will be deformed; When the temperature is too low, it is easy to drop oil or the oil drops are too small.

6. Electric burning is characterized by rapid temperature rise in the early stage and slow temperature rise in the later stage. When the highest firing temperature is reached, there will be a plateau period to keep the high temperature, and then it will enter a cooling period. The high temperature plateau period is very important in the firing process, because the formation of speckle is closely related to this stage.

7. Reducing flame atmosphere is a characteristic of traditional dragon kiln firing, especially in the firing process with pine as the main fuel. The current electric burning is different from the traditional fire reduction. In order to improve the quality of the lamp, it is sometimes necessary to artificially create some reducing atmosphere.
