Folk also known as "Bashan jade" "jade mountain", and some called "hard sodium Jade", "albite jadeite" in the classification of "species", there will be listed as "eight Sanyu species."
The petrology name of Yaosanyu is "alteration of jadeite rock." Semi-automorphic - he grain granular crystal structure, fibrous deformed crystal structure, band structure, fragmentation structure, fissure structure, Soleil structure, breccia structure. The jadeite minerals are obviously recrystallized by extrusion, deformation, wavy extinction and jadeite recrystallization. The grain size of the jadeite mineral is generally above 1mm, and the maximum measured value is up to 4mm. The grain size of the jadeite mineral after crushing and graining is generally above 0.01mm.
The structure, structure, and mineral characteristics of Yaosanyu comprehensively reflect that the altered jadeite rock is a result of intense geological stress. Therefore, the microscopic cracks, microfissures, and intergranular crystal clearances of the Yaosan jade are well developed. It is also very common for jadeite cleaving to break open during deformation.
The original transparency of the 83 yams is related to the grain size, crack development, and alterations. The grains are large, the cracks are small, the alterations are weak, and the enamel is generally transparent, and the opaque-micro-transparent shape is usually optimized. Translucent.
Eighty-three jade colors are milky white, grayish white and light green, and the background is often embroidered with green, dark green, dark green clouds, disseminated, and lumps.
The mineral composition of the altered jadeite rock is mainly jadeite, a small amount of omphacite, alkaline hornblende, and submermetite are alteration products.
Through a large number of tests on the 8.3 bracelets, the 8.3 jade should be located in the jade range consisting mainly of jadeite (90%), and the sodium feldspar made of albite is not in the category of 8.3 jade.
Eighty-three jade loose due to the inherent structure, most need to optimize the process, the internal eighty-three jade and exterior surfaces with a polymer filling method to achieve perfection, but eighty-three jade can not agree to "B goods" concept.
The Baysan Jade “B-goods†is the best example of polymer filling in the optimization process. It is the best position for jade and is the most effective use of jade resources.
Eighty-three jade "B goods" appeared to be accepted first met Jade consumers, mainly due to an eight Sanyu "B goods" have a good physical beauty, to adapt to cheaper prices in the border areas (Tengchong, Ruili ) The wholesale price of jade bracelets is generally 200-300 yuan / only.
Eighty-three jade "B stock" bracelet is the main product, mostly opaque white background, light green, translucent, often green, dark green floating flowers, with blue fluorescence under ultraviolet, density of 3.30g / cm3, With rice field dry structure, percussion jade body sound dull.
In order to make the eight-three jade "B cargo" jade bracelet texture and color can be maintained for a long time, when wearing should avoid soaking in hot water, sun exposure, often scrub with a wet towel, blow dry after polishing on the velvet, avoid using Organic solvent (alcohol, banana water) scrub.
Dyeing is a relatively complicated process. The process of dyeing different quality fabrics is different, such as cotton, polyester-cotton, nylon, polyester, chemical fiber products, blended products and so on. Some use padding, dyeing can be, and some must use high temperature and high pressure dyeing, some only dye once, and some have to be painted multiple times.
Although dyeing can be done through a rolling mill, it is also the most difficult process, because the color control of dyeing is not only known, but also many unknown things, such as the stability of dyes at different temperatures, steam Control, control of rolling car pressure, etc., are very fine work.
The dyed long car is divided into two parts, the front car is dyed, and the rear car is fixed. The dyeing method varies according to the type of dye used. They all have their own advantages and disadvantages. Generally, they depend on the required color and cannot be replaced.
