What is the difference between hard seed introduction and soft seed introduction of turquoise raw materials? Too comprehensive.

Hard seeds grow together with rocks, and the structure is compact, so explosives are needed to operate when mining. Hard lead generally contains inevitable substances such as iron wire and flint, and many impurities need to be removed in the production of finished products! Most of the hard-extracted turquoise has the characteristics of high density and hardness, and belongs to the first-class turquoise material of porcelain pine grade. What is porcelain pine? The surface gloss of finished products is as bright as glazed porcelain, and the fracture of semi-finished products or woolen products is like porcelain, which is called porcelain pine! )

Soft seeds are generated in soft soil mud and do not need explosive mining! Most soft seeds do not contain iron wire or other substances, so they are very suitable for carving products, because their interior is very clean, and they are also called plain materials and pure materials! The loss rate is very low, and it is a favorite seed material for wholesalers and sculptors. When soft seeds are unearthed, the outside is black, and the soil on the surface can be removed by brushing with a toothbrush, revealing clean stones.

It is difficult to tell whether the raw materials of the finished product are soft or hard. But what is certain is that the finished product with thicker and denser wire is likely to be hard-drawn.
