The smooth stone is mirrored on the front, and the brilliance and flatness are very high. Washed surface also depends on the hardness of the stone, some of the stone after washing the effect is matte, some stone has a bumpy feeling after washing. (said that washing is usually done with sulfuric acid)
The lychee surface is made by hammering the surface of the stone with a hammer shaped like a lychee, so that a rough surface shaped like a lychee skin is formed on the surface of the stone, which is more common on the surface of the sculpture or the surface of the square stone. It is divided into two types: machine surface (machine) and hand surface (manual). Generally speaking, the hand surface is finer than the machine surface, but it takes time and labor.
Litchi stone is not a kind of fire surface. But they are all ways of roughening the surface of the stone. The way to roughen the surface is as follows: 1. Natural kneading surface 2, mushroom surface 3, singeing surface 4, machine planing surface 5, sandblasting surface
The difference in surface texture is: the lychee surface stone is the kind of stone whose surface is convex, and the fire surface is mostly recessed.
