It comes from the experience summed up in labor practice by ancient Chinese porcelain craftsmen.

Who would do the porcelain work without diamonds? This proverb is the experience summed up by the labor practice of ancient Chinese porcelain craftsmen. It is an old saying. It has become a proverb after being passed down by word of mouth. What it expresses is that some things may seem simple and inconspicuous. If you really have to do it, not everyone can do it if you don’t have the professional level. If you don’t have the professional level, don’t stand out.

"Curium porcelain" is an ancient Chinese handicraft.

The broken porcelain is cured with metal nails such as copper, iron, tin, etc., so that the porcelain can be repaired and used again. The saying "If you don't have diamonds, don't do the porcelain work" comes from the curium porcelain industry. . With people's pursuit of material life, ordinary porcelain will be thrown away when it is broken. Gradually, this industry will decline, and the curium porcelain craftsmanship will gradually be lost. The picture shows the purple clay teapot restored by Chen Ying.

So what should we do if such exquisite and high-end porcelain broke in ancient times? Throw it away, what a pity! Don't throw it away, it won't be used, and it takes up a lot of space. In order to solve this problem, a group of craftsmen who specialized in repairing porcelain were born in ancient times. There are two main tools for these craftsmen, one is a diamond and the other is a nail.

When repairing porcelain, first use a diamond drill to drill a small hole in the porcelain, then use a curium nail to penetrate it, fix it, and finally polish it to fix the leak. After such a set of procedures, although the porcelain is not intact as before, it is enough to be brought back to life and can be used normally. It only has a few scars on the body, but it looks more rough and vicissitudes of life.
