Description
Technical Field
The invention relates to an improvement of a production process of jewelry, in particular to a process for combining paint and eggshell with metal jewelry.
Background
The use of natural paints, eggshells, mother-of-pearl and like materials for decorating household utensils has been known for over 7000 years by man. Paint culture is taken as world-level non-material cultural heritage and is protected by 'Protect non-material cultural heritage convention' organized by United nations textbooks, and is in an endangered state due to poor ecological circle of traditional handicraft industry in recent years. It is necessary to inherit innovation and popularization. The combination of the lacquer art eggshell inlay and the modern metal jewelry production process is an innovative form which is more flexible and can more widely and effectively spread the lacquer culture.
The important reason why the lacquer eggshell splicing technology is not widely applied to jewelry in modern times is that the cheap raw materials and the glittering, translucent, black and bright color effect of the lacquer eggshell splicing technology cannot meet the requirement of the master for showing the rank identity status like rare precious stones. However, in the second half of the 20 th century, the tension of people is aggravated along with the rapid pace of industrialization after the second war, the traditional jewelry production form is not available, the mental requirements of people are met, most of art smiths begin to pay attention to contemporary jewelry, and the meaning of thinking back that jewelry is used as a collection of precious metals and precious stones as a sign of status and more possibilities of discussing the development of the jewelry. With the development of modern science and technology, the thinking trend of the traditional handicraft art starts to revive, people have strong willingness to conservation of ancient culture, and equipment is advanced day by day due to the large scale of industrial production, so that more possibilities of the shapes of the eggshell ornaments of the lacquer disclosed by the invention are created.
The prior paint jewelry in the market is formed by combining a wood blank lacquer changing means with a knot link, has no infinite plasticity three-dimensional shape of metal, and has a single structure. Although the academics have searched for metallic paint jewelry, the metallic paint jewelry only stays on a plane to have a variable coating effect, has no breakthrough on a three-dimensional curved surface, cannot be industrially produced, and has no obvious characteristic of pasting an 'eggshell' which is a very important element of the antique paint device. The traditional handicraft of egg shell splicing in the lacquer art and the industrial production process of metal jewelry production belong to two different fields respectively, and the technical and cultural boundaries of each other are difficult to break through. The invention breaks through the pure handiness of the paint cultural ring and the homogenization and mutual fusion of the precious metal and precious jewelry materials in the jewelry industry, and utilizes the computer to control the processing and manufacturing, so that the paint cultural ring and the precious metal and precious jewelry materials are suitable for industrial production and are integrated into modern life.

Detailed Description
The following detailed description is provided in conjunction with the embodiments and with reference to the accompanying drawings in order to provide a further explanation of the technical features and advantages of the present invention.
In the invention, the paint is natural lacquer, the water content is about 6-8%, the viscosity is suitable for being adsorbed on the treated metal surface, and the natural orange oil is used for blending, and the drying environmental conditions are generally that the temperature is 20-28 ℃ and the relative humidity is 70-75%. The eggshell is the eggshell of poultry, the thickness is suitable, and the color is light yellow or white. The eggshell is preferably removed from the middle part of the top and the bottom, and the eggshell is processed according to the air temperature and the vinegar concentration, and the proportion of vinegar is 1: adding water in a dosage of 20 to soak a fresh eggshell for 2-4 hours, then taking out the eggshell underwear, only leaving a calcium layer, completely soaking and washing the eggshell underwear with clear water, and taking out the eggshell underwear and naturally drying the eggshell underwear for later use. The metal is high-purity precious or base metal and various alloys without health threat.
When the lacquer is used as a liquid raw material, the density of the lacquer per se can form tension on the edge of the rabbet, so that the surface is reduced as much as possible, and the lacquer is more firmly attached to the surface of the metal or the base fabric in the drying process. The bottom cloth refers to plant fiber cloth covered on the substrate. The base plate is a plate which is made by covering a substrate with rough plant fiber cloth, tightening the edge with an instrument and painting. The substrate can be a hard flat plate with a smooth surface, such as ceramics, glass, polished marble and the like, and the 'lacquer shell cloth' veneer is convenient to peel. The hard substrate with smooth surface can be repeatedly used, and is suitable for processing three-dimensional mosaic. When the base is a wood board, the base board is directly made of lacquer, and the decorative surface made of the lacquer board can be integrally subjected to linear cutting to form a decorative surface part combined with a wood lacquer shell, so that the decorative surface part is suitable for processing plane inlaying. In addition to the two above methods of peel-off machining, the third method of tessellation to which the present invention relates is a manual "micro-tessellation" operation.
The process for manufacturing the metal blank is mainly characterized by the design and processing of the rabbet, the rabbet design is that the thickness of an eggshell is about 0.3 mm-0.35 mm, and only the eggshell with the thickness higher than the thickness or the rabbet with the thickness of the eggshell and the substrate is reserved on the processed metal part, so that the paint is not easy to overflow and separate from the metal. The shape and height of the rabbet vary according to the specific design and the embedding technique, the rabbet and the paint surface are in a state of being parallel to an organic surface, the organic surface refers to one of the shapes of a 'surface', and the rabbet and the paint surface cannot be obtained by a mathematical method similar to the geometric shape, but the rabbet is also rich in order and law. Although the metal blank can be formed by casting or machining or 3D printing, in view of cost, a casting mode is mostly adopted in the general batch production process, and then the product with higher value and more artistic aesthetic feeling can be obtained by combining artificial modification.
