The effect of human processing on gloss. Stone gloss meter manufacturers tell you that human factors mainly refer to processing skills and processing technology. 

Stone gloss meter manufacturers tell you that the same material is handed over to different people, and the quality and gloss of the processed finished products are also different. The same material is processed meticulously, the gloss value of the delicate one is relatively high, and the gloss value of the rough processing is relatively low.
Stone gloss meter manufacturers tell you that it needs to be explained here that the measured value of gloss varies according to the angle of the incident light. Common gloss meters mainly have three measurement angles: 20°, 60°, and 85°. As the angle of incidence increases, the gloss value of any surface also increases, so the angle of incident light must be determined when measuring specular gloss. When expressing the specular gloss of the stone, the angle must be indicated.
The above information is the Stone gloss meter manufacturer's introduction and analysis of some factors that affect gloss, hope it helps you.
