South red agate, also known as' Red Jade ', happens to be the auspicious color of the Chinese people, representing enthusiasm, festivity, red fire and good luck. The red of South Red perfectly corresponds to China's red culture inherited for thousands of years, and is deeply loved and worshipped by people who play games. How can agate be identified? Next, I'll introduce you and listen to the experts.
Hongbi stone vs. Nanhong stone:
Look at the quality
Hongbi stone has no texture of jade. It's very dry and has no oil. To put it simply, it's like a stone dug out of a hill. It's just red. Nanhong is a kind of jade, which has a clear sense of colloid. Many friends often hear this word, but they don't understand what it means. In fact, 'colloid' is like coagulated glue, viscous and stagnant. It seems transparent but not completely transparent, hazy and fuzzy. Even if it is colorless ice floating in Nanhong, its transparency is worse than that of glass. It is delicate and moist in the hand.
Light up
Red and blue stone is very good. Can you make light by lighting? Don't even think about it! There is no red aperture around the red sapphire flashlight, while the South Red Agate is full of nature. Even if the south red is full of color and meat, it will have a slight penetration when it lights. If the south red is ice floating or dissatisfied with color, it can clearly see the cinnabar spots inside, which is not found in the red sapphire. This move appraisal is very direct, a flashlight can be done!
Look at the color
Hongbi stone is also known as Wushi, because its red color is not gorgeous, not bright, dark, not pearly, lifeless. The red of Nanhong agate is very bright, with a kind of ruddy feeling. We need to see more real objects to cultivate the intuitive feeling of different 'Red'. Burnt agate vs. South Red Agate:
Firing agate is to use the firing heating process to oxidize the divalent iron ions in ordinary agate to trivalent iron ions, so that the light gray agate will turn into red agate, and then hang the label of 'South Red' to deceive. This technique has made a lot of players suffer, because burning agate can make the color very red, which is difficult for novice players to recognize at the beginning.
Look at the color
After all, the burnt red is not natural, but cosmetic. It never has the temperament of natural south red agate. The burnt agate red is unnatural, most of which are deep red, dark red and maroon. Some of them are yellowish, not bright, and the color floats on the surface. The burnt agate is essentially some grayish light color agate, so it has high transparency, high light permeability and low glass permeability Strong texture.
Look at the lines
As the firing color is processed at high temperature, obvious willow fire patterns will appear on the agate beads, which can be clearly seen under the light transmission. Of course, this kind of fire pattern should be distinguished from the flame pattern of the South Red Agate itself. The fire pattern is like a piece of small willow leaves, with a feeling of small mouth cracking. It is independent and separated from each other, and relatively evenly distributed on the beads. The flame pattern is a special beautiful texture of the south red agate, which has no rules, can be thick or thin, and can be gathered in pieces. The color is gorgeous, like a burning flame.
Look at the channels
There will be obvious light color small ring opening in the channel of burnt agate, which is caused by uneven heating and is obviously the result of later processing. It is absolutely impossible to exist on natural south red agate, because its color can not be changed due to drilling. This move has been tried repeatedly, we must remember it! Look at the pictures below. The first picture is likely to confuse many people, while the second one shows its true shape.
3、 Dyed agate vs. south red agate
The color of dyed agate is even more fake. It is mostly soaked in dye. The red color is quite unnatural. It is very transparent and has glass texture. The color is deposited in the gaps and cracks of agate, and there are uneven color spots, which are more obvious when observed under a magnifying glass. The biggest weakness of agate dyeing is that it will fade, and any organic solvent can be used to wash the bubbles! Let's not go into details.
The above is my little summary of the identification of Nanhong agate. This is a big problem, but we can only make a long story short. I hope it can help you. For novice players, let's not always think about taking advantage. Don't look at the red stone and think it's south red agate. Don't look at the super red and cheap one and think it's missing. The price of South Red Agate full of color and meat will never be low, but the price of dyed and burnt agate is really cabbage and rotten! It's more reliable to cover your purse, learn more and start more, spend dozens of yuan to buy a book to read, or talk to me more.
