Do you know what are the most cost-effective cinnabar models in the pressing process?
The first water flying red sand: the water flying red sand that we have inherited for the longest time is red sand made of natural cinnabar ore particles by grinding, cleaning and water flying filtration into flour. Its high purity is mainly used for pigment inkpad painting or medicine, and it needs to be pressed with glue to make ornaments. The advantages are that the powder is fine and the density is high, and the number of times of filtration is relatively small, so the natural purity can be high, but it will not exceed 90. The hardness is low, and it is easy to stain after a long time.
The second purple sand: purple sand is improved by the merchants in view of the shortcomings of the first generation of red sand ornaments. It can be said that purple sand is specially used as ornaments. Purple sand is made of cinnabar fine particles formed by natural ore crushing, grinding, screening and impurity removal, and then pressed with glue. Purple sand is reddish in color, with obvious mineral spots on the calm atmospheric surface, and the appearance is full of stars, and the mineral flash particles are more natural and uniform. Hardness is higher than that of red sand, and it is more resistant to manufacturing and less prone to fouling. The purity is about 80 to 85. Disadvantages: too much artificial reduced sand is easy to buy fakes. The color of purple sand made of artificial reduced sand is dark red or sauce purple red, and the color of natural sand is usually purple red.
The third type of fully permeable crystal sand: the fully permeable crystal sand is harsh in material selection, and it is also the best high-quality sand for pressing cinnabar. The large-particle cinnabar that needs to be knocked down directly from the ore should be screened for the same size, and then the large-particle sand with ruby color and fire color should be manually selected, and then the large-particle sand can be wrapped and molded with glue, so that large particles can be seen on the surface of the crystal sand, which is transparent under illumination, and the output of the upper-grade red light is less, which is more valuable. Because of the problem of large particles, the purity of the finished product it makes is generally about 83. However, the purity of crystal sand particles is high, so the beads of the same size will be heavier than red sand and purple sand. Because the growth cycle of crystal particles is relatively long, the output is relatively low, so it is also the most expensive sand in cinnabar. However, if the sand is not carefully selected, it will affect the transparency and beauty of the finished product, which will also affect the price.
As for other suppressed cinnabar products, manufacturers use sand with different particle sizes or mixed raw materials when selecting raw materials, and then the surface color and appearance of the finished products are different by the same process. Just think of a new name to raise the price and make money. If you like it yourself, the price can be considered in your budget. Some merchants have to smash the pot and step on it for 10 million in a bowl, so don't be biased. This kind of person will not be able to do it for a long time.
