Answer three of the questions that Tao friends asked yesterday. If you have any questions, you can also put them out in the message area. Let’s discuss them together.
1. Can the electric kiln burn firewood?
A: the effect of wood burning is mainly about the fire marks and natural falling glaze. The fire marks are mainly caused by the trend of fire. The falling glaze is the result of the burning wood ash and the spilled wood oil (such as pine oil) dropping on the pottery.
There is no open flame inside the electric kiln, and there is no wood ash and diesel dripping, so it is impossible for the electric kiln to burn firewood under normal operation. However, if the glaze is sprayed on the pottery in advance and changes due to high temperature, the grey glaze effect like wood firing may be produced.
2. Is Jianshui purple pottery breathable?
A: the water purple pottery belongs to pottery, and naturally has certain air permeability. Even stoneware between pottery and porcelain has a certain permeability and water absorption before vitrification.
Only when the vessel is fired to porcelain or vitrification, there will be no air permeability and water absorption. In fact, purple clay belongs to the scope of stoneware, with double porosity structure; the sintering degree of Jianshui purple pottery is similar to that of purple sand, so Jianshui purple pottery also has certain air permeability.
3. Which is better, Jianshui purple pottery or Yixing purple sand?
In fact, one of the most frequently asked questions is that I have been asked many times. My point of view has always been: Jianshui purple pottery is different from Yixing purple clay because it is made in different places, with different clay materials and different crafts. The most important thing is that the cultural background is also different. However, it is only the difference between the two kinds of pottery, and there is no difference between the advantages and disadvantages.
One example I often cite is that different cuisines are different in taste, bitterness and bitterness. However, we can’t say who is good and who is bad. It’s just the difference that I like.
