When you enter a purple pottery shop and hear the owner introduce that a certain piece of purple pottery is decorated by “window opening”, you may be very confused for a moment and can’t respond to it. What does “window opening” mean?
A little more popular explanation, when decorating purple pottery works, some people will carve out a block surface with different color from the pottery body in advance, and then carry out calligraphy and painting decoration on this block surface, and this block surface is “window opening”.
“Window opening” is not the dialect of Jianshui, nor is it a unique decorative technique of purple pottery. In history, there are many “window” decorative ceramic works, especially in porcelain.
“Window opening” belongs to a kind of painting technology, which is to highlight the key points on the surface of objects, and is reflected by different colors or shapes. It is similar to the window.
“Window opening” is also in the layout, which is equivalent to making a piece of paper on the pottery surface first, and then arranging the structure and size of calligraphy and painting when the size of the paper surface is known. “Opening the window” in advance can not only make the decoration content more prominent, but also help to decorate the work more strictly.
