The common colors of south red agate are brocade red (including persimmon red), rose red, cinnabar red, red and white material, red material and cherry red, which are roughly defined as the color types of south red. These transparent or translucent colors, including almost transparent colorless, are roughly defined as the color range of Nanhong.

2, modeling and patina

As far as shapes are concerned, the common ones are olive-shaped, round, pumpkin-shaped, flaky and faceted beads (6-sided, 8-sided, 12-sided, etc. ), and all kinds of carvings are mainly fake olive-shaped and round beads on the market now. It should also be noted that the old bead has been worn with other beads for hundreds of years, so the two ends of the hole will wear like a cut surface.

It has been found that the real beads on the patina are also dry, but they are by no means the obvious polished surfaces of the new bonfire or new beads. The patina of Laozhu is always oily and natural.

3. Texture

South Red Agate is a unique variety in China, with delicate texture and scarce output. Generally, south red agate is made of rubber. Even if all the red, south and red beads are observed by light, the color can be seen from the inside out. Colorless south red beads will also have a hazy feeling when observed with the naked eye, as well as a glossy feeling similar to Hetian jade.

4. Weathering line

In the appearance of beads, most of the old beads, especially the old chalcedony/Kate Ma beads, will have a half-moon weathering pattern. At present, there are no weathering lines on the dyed Nanhong produced in batch, and most of them are cracks on the surface of agate when it is directly fired at high temperature.

5, punching and punching

The perforation of south red agate is very characteristic. It may be that the big material punched holes on both sides before beading (the holes will not be very small). After long-term use, the hole is very smooth due to wear.

If there is obvious spiral and white powder in the hole, it can be judged that there is a new work or a suspicion of dyeing South Red.
