The gloss of the stone has a theoretical gloss, polished gloss and the actual polished gloss. In principle, the theoretical gloss can be calculated by calculating the mineral absorption, reflection and refraction of light. The polishing gloss is calculated by considering the weathering of the stone, the density of the structure, the color change, the disintegration of the mica, And other factors that affect the stone gloss calculated; the actual polished gloss obtained by the actual operation of the gloss, which in addition to the stone natural factors, you can say a lot of human factors. Such as the construction of the grinding method, the results of construction and grinding, stone recrystallization hardened sheet dryness, stone recrystallization hardening ambient temperature, stone recrystallization hardening method and crystallization hardening agent selection and so on. The presence of all these uncertainties affects, to a lesser or greater degree, the result of recrystallization hardening of stone.
