The difference between trimming and beneficial blank.

Blanking, also known as "trimming", is a process of blank drawing. It can be understood as equivalent to completing a blank room, and then you have to do fine decoration on this blank room. A good blank is a blank house, and a good blank is a fine decoration. Trimming can be roughly divided into two categories, rounding and cutting. Circular tools require absolute concentric circles, and tools are generally blank bodies formed by pressing, grouting and printing, and concentric circles are not required. Generally speaking, it is the difference between high-end porcelain and low-end porcelain.

Like drawing blank, drawing blank pays attention to basic skills, and its basic skills are called sharpening. If you want to learn how to grind blanks, grind them for three years before touching them. This process is very boring, and any skill must confirm the sentence: "Heaven will be the great task of Sri Lankan people, and we must first suffer its ambition." Will power first.

Jingdezhen ceramic craft has four characteristics: Yan Ruyu, as bright as a mirror, as thin as paper and as loud as a chime. As thin as paper here refers to the process of benefiting the blank, so the skill of benefiting the blank is one of the factors that determine the quality of ceramics.
