carving process and evaluation of crystals

Crystal, belongs to the formation temperature in the 573℃ below the tripartite crystal system Si O2 single crystal, human exploitation, use and trade of its history is very long.However, for a long time since the crystal has been attributed to the ranks of low-grade gemstones, resulting in the market most of the crystal sculpture homogenization, commercial value, artistic value is relatively low.This paper summarizes the characteristics of gemology of crystal, analyzes the current status of related crystal market, and organically combines the characteristics of crystal, processing techniques and process evaluation methods in order to achieve innovation in the design mode and improve the quality of product technology.Based on the research on the properties of crystal gemology and market research, the characteristics of crystallography, optics and mechanics are summarized.At the same time, according to its characteristics and business habits into different categories: by color can be divided into topaz, amethyst and smoke crystal varieties;According to the shape and phase of inclusions can be divided into hair crystal, ghost crystal, strawberry crystal and water bladder crystal varieties.According to the characteristics of specific species analysis of its impact on sculpture, in order to highlight the creation of its characteristics, in the process of carving can also draw on advantages and avoid disadvantages.In addition, the crystal processing technology is studied in detail.This paper summarizes the development history of crystal processing technology, summarizes the common crystal carving themes and contents, and briefly describes the crystal processing equipment.At the same time, the summary of the crystal processing process is generally divided into material review, miscellaneous, design drawings, carving, polishing, polishing and accessories decoration.In addition, through practice, focus on the crystal carving techniques such as round carving, relief and concave carving, and crystal polishing techniques were practiced
