When talking about lacquerware, Mr. Ma Weidou once mentioned that in ancient lacquerware technology, the surface of lacquerware was "cut" by filing grass and polishing. Where did this technology come from? This time, he was wrong. The ancient lacquer craft is polished with tile ash and hair. The so-called archive grass is actually called grass. It looks like a hose about seven or eight centimeters long and looks like a reed. When the inner wall is cut, there are small thorns. The ancients used it to polish ivory, which is still the case today, and the effect is very good. There has never been a record of polishing lacquerware in ancient books such as the Record of Joining the Masters.
