Stone is made up of a variety of minerals. The composition of marble is relatively simple. It is mainly composed of calcite (CaCO3) and dolomite (MgCaCO3). Granite is much more complex, so the gloss expressed by various minerals that make up granite is also the average gloss of mineral aggregates. .
The gloss of the stone has theoretical gloss, polishable gloss and actual polished gloss. In principle, the theoretical gloss can be obtained through the calculation of the absorption, reflection, and refraction of light by minerals; the polishability can be considered in the weathering of stone, the density of tissue structure, the discoloration, the crushing of mica, and so on. The factors that affect the glossiness of the stone are calculated and calculated; and the actual glossiness of the polish is the glossiness obtained through the actual operation. In addition to the natural factors of the stone, it can be said that there are many artificial factors. Such as the method of construction grinding, the result of the construction grinding, the degree of drying of the stone recrystallized and hardened sheet, the environmental temperature of the stone recrystallization hardening, the method of recrystallizing and hardening the stone and the selection of the crystal hardener, and the like. The presence of all these uncertain factors more or less affects the result of the recrystallization hardenability of the stone to varying degrees.
