What does diamond drill mean

Vajra drill, a tool, in the old days there are some craftsmen (generally saw porcelain craftsmen), specializing in the use of this tool (vajra drill) in the broken porcelain drill holes, used to repair broken porcelain (a process known as "curium"), such as bowls, bottles and so on.

Introduction of diamond:

"Diamond" is a foreign word, with Buddhism from India. To the Ming Dynasty, Li Shizhen research diamond found that it can not only cut jade, but also can be drilled in jade or porcelain, so it is called "diamond".

"There is no diamond drill not to take porcelain work." This saying is used by the ancients to curium dishes and bowls and other porcelain a repair old porcelain process, porcelain firing texture brittle and hard, want to drill holes in the top only diamond drill can be, jade is also.

In the old Beijing hutongs in the past, it was common to see some shoulder-carrying craftsmen, who relied on their own masters or family traditions of craftsmanship, every day on the streets, for the people of the capital's home repair, rely on the family to support their livelihoods.

Then the life of the Beijing people are not rich, usually live a life of great attention to thrift, the use of tanks, pots, bowls, plates, if broken, as long as the ballast on the mouth, will not be willing to throw away, to spend a couple of money to find the craftsmen curium curium then use. At that time, there are specialized in this kind of work of craftsmen, Beijing people called them: "curium bowl child".

They picked the stretcher, one end is a cabinet, the style is like the past restaurant fellows to people with food boxes. Cabinet has three or two layers of drawers to put the size of the curium, beam hanging on a copper, like a rattle like thing, walk up when the stretcher shook, it will be issued: clang child! Clang! Rattling, people sitting at home to listen to the sound, you know that there are curium bowls over.

Doing this line of work, most people are more than forty years of age, many are masters, work with glasses, first look at the ballast, estimated to use a few "curium", and then say the price.

There is a saying: "curium bowl child wearing glasses; no ballast find ballast". This is probably where it comes from. The tools used for curium bowl is very simple, a drill like the size of a grain of rice, a bow like a huqin, but the bow is not tied to the horse's tail, but a thin rope.

With it wrapped around the drill, pulling it back and forth, the drill drilled holes in the slippery, brittle porcelain, like an awl on tofu, really easy.

The little drill is what people often call a "diamond drill". Don't look at it "small" that is the main tool for survival in this line of work, a stretcher added up to the value of the value of a "diamond" is not worth the value of a "diamond" value of money, without "it" on what also Without it, nothing can be done. So there is that sentence: "no diamond, do not take porcelain work ah.
