Description
Chemical Composition
| The composition of Yuhuashi is mainly silicon dioxide, in which the red component is iron ion and ferrous ion. Yuhua stone is a pebble whose stone quality is agate, opal, chalcedony, quartz and so on. It is found in the sediment of riverbed and river terrace, among which the most famous is Yuhua stone produced in Nanjing Liuhe Liangliang Town (the hometown of Yuhua Stone). | |||
| Yuhua stone is divided into two categories: fine stone and coarse stone. Fine stone is mainly agate, exquisite stone, gorgeous color, high roundness, crystal lovely; Coarse stone is coarse, mainly quartz or metamorphic rock, low value. Beautiful Yuhua stone can often present a variety of landscapes, figures, birds and animals, trees and other scenes, people reverie, thoughts into the stone, very beautiful. Because of the variety of Yuhua stone, its genesis and chemical composition is very complex. Take agate gravel, which is derived from primary agate. It is generally believed that primary agates are formed from the residual heat of magma. This hydrothermal fluid is filled in volcanic rocks such as basalt, rhyolite void, depending on the shape of the void, or into agate balls, or agate veins. Through the action of natural forces, the primary agate falls off, and then through the impact of mountain floods, water transport, ground into pebbles. This is the rainflower agate we see in the gravel layer. | |||
| Yuhua stone is famous for its strange pattern and brilliant natural beauty. Its ring pattern is silica gel liquid around the volcanic rock void, cavity, starting from the inner wall, from the outside to the inside layer by layer precipitation. During its growth, periodic diffusion of colored ions and compounds often occurs. The main chemical composition of primary agate is silica, followed by a small amount of iron oxide and trace elements and compounds such as manganese, copper, aluminum and magnesium. They themselves have different pigments, such as red for iron, blue for copper, purple for manganese, yellow translucent silica colloidal stone pulp, emerald color with green minerals and so on; Because of the different kinds and contents of these pigment ions dissolved into the hydrothermal solution of silica, they show a variety of colors in intensity and depth, making Yuhua stone extremely gorgeous and beautiful. | |||
| Cobblestone is named after its resemblance to a goose egg. As a kind of pure natural stone, pebbles are taken from the sand and stone mountains produced by the uplift of ancient riverbed after the crustal movement tens of thousands of years ago. They have experienced the impact of mountain floods and the continuous extrusion and friction in the process of moving water. |
