Experts from Shanghai Geology and Mineral Jewelry Testing Center talk about "Yu Shuhua"
Silicified wood and lignified jade
Author: Shanghai Geology and Mineral Jewelry and Jade Testing Center The largest "Hutai Flower Stone Market" in Hu Jiayan and Shanghai is located at Hutai Road 10 12, with convenient transportation, and more than a dozen buses stop at the entrance of the market (Yichuan Road Station). At the beginning, the market was dominated by flowers, with several novel greenhouses lined up, full of flowers and trees in the south, as well as universities and some commercial shops in Shanghai, with only a dozen strange stones. Recently, the author went to a market with foreign tourists, and some changes have taken place, such as the decrease of flower marketing and the sharp increase of strange stone shops. The main products are silicified wood, and the shops are still open.
Silicified wood comes from all parts of the mainland, and many of them come from Myanmar border trade market and Southeast Asia. It has become one of the largest silicified wood markets in China and the distribution center of silicified wood in China.
Where there is demand, there is a market. When the market meets the demand, it further stimulates the demand to develop to a higher level. This virtuous circle makes a group of new people join the ranks, and the competition is becoming more and more fierce. Therefore, the development and processing of silicified wood ornamental stone should be improved, and the supporting pedestal processing also came into being. Hard miscellaneous wood, mahogany and rosewood can be freely selected according to the quality of silicified wood.
Silicified wood, a tree fossil formed hundreds of millions of years ago, has now entered the homes of ordinary people and the business halls of companies, leaving a place for silicified wood. Hundreds of millions of years of silicified wood have added splendor to the living room and added style and auspiciousness to the hall. Silicified wood is the name of fossil, which grows in geological history. It was buried under the influence of geological changes. In a certain geological environment, it has suffered from different degrees of silicification. Siliceous minerals with different crystal forms and types such as Yingshi, chalcedony and opal are displaced and replaced along the thin cells of wood, forming siliceous wood fossils with residual wood fiber cell structure.
Silicified wood can be named after tree species, such as pine silicified wood, cypress silicified wood, ginkgo silicified wood, Metasequoia silicified wood and so on.
Huamu jade must have the definition of jade, and it must be a natural, beautiful, durable, rare and valuable mineral aggregate, and a few are amorphous.
Silicified wood produced in nature, due to the difference of silicification degree, the variation of internal mineral composition, some are dense and hard, some are porous and loose, and some silicified wood is manually pulverized.
Huamuyu is a kind of jade containing silicified wood. Some silicified wood has a good appearance, but its "jade degree" is poor, so it can be listed as "silicified wood ornamental stone". Some silicified wood with good shape and jade degree can be listed as "Hua Mu Jade Ornamental Stone".
As a raw material of jade, Huamu jade can be processed into different jade ornaments. Slice the egg surface of wood fiber cells perpendicular to Huamuyu to get Huamuyu cat's eye.
At present, in the silicified wood market at home and abroad, in order to highlight the jade feeling effect of lignified jade, one side of the ornamental stone of lignified jade has been polished and polished. The surface is smooth and radiant, while the other side maintains the original appearance of silicified wood fossils, which is rich and extensive and embodies the vitality of time.
