Let me explain

From the appearance:

1.? Litchi surface at a glance to know is manually processed, there will be a more uniform destruction of the surface, there are obvious more regular particles out, of course, this has to do with the operation of the person and the machine has a relationship with the effect of a rough surface. Sort of like the surface of the lychee raised particles of feeling, size, the distance between the particles and particles is very regular! Look at the picture

2.? Fiery surface of this with the choice of stone has a great relationship, if it is the Fujian 603 axe chopping and Fiery is really close, because the stone particles crystallized small.? If it is the sea wave flower this stone is not the same, because the stone has the size of the crystallization of the difference, after the fire, the size of the crystallization of the collapse out of the surface effect caused by the natural, there is a kind of nature after many years of weathering caused by the bumpy effect, if this stone with an axe chopping, then it is also still uniform surface particles, the gap is still relatively large!

I hope so that the owner can be clear!
