When purple pottery is filled with mud, it is necessary to pay attention to the following situations:
In order to avoid color string, different color blocks need to be completed in different times.
The most typical is the remnant paste, the bottom plate is generally composed of several pieces of different colors. If the adjacent but different color blocks are filled with mud of different colors at the same time, the edge of block faces will be prone to cross color.
If the color blocks are not adjacent, mud can be filled simultaneously even if the colors are different. The color block is not adjacent, and its edges will not contact, so there will be no color string.
Writing on the surface of pottery is an independent distribution, which is equivalent to non adjacent color blocks. Therefore, the mud filling can be completed at the same time whether it is the same color text or different color text. Common, such as white text and red signature seal, are all one-time filling mud at the same time.
In addition, there is no need to fill the mud by stages without considering the cross color or the transition color with no fine decoration. We often say that a gouge color filling is such a case, mixing different colors of mud together, one-time can fill out color decoration.
