What are the characteristics of the size of southern red envelopes? The so-called bag size in Nanhong is actually a guide to the outer layer of red agate. The southern red material with this coating is commonly known as the size of the southern red envelope. The coating material has dual properties, which can be used as both jade carving material and strange stone. Coating slurry is mostly found in Sichuan South Red Agate, which is the top grade in the original stone. Generally, it is small in size, smooth in skin, with strong gelatinous texture and fluidity, just like the patina formed by playing with cultural relics for many years, hence the name. There is generally a layer of black stone with pig liver color under the skin of the stone wrapped with pulp, and under the black stone is the south red agate with unusually bright color and thick texture (persimmon red, unfrozen and rose red are common). Because its skin color and flesh color are very good, it can be directly used as a hand stone or carved with skin.
Whether it is the original stone or the finished product, it will become more gorgeous with a little play. The density of coating slurry is higher than that of ordinary South Red Agate rough stone, and it feels like jadeite. The hardness is also higher than that of ordinary South Red Agate rough stone. When cutting, you can obviously feel the blade walking slowly on the stone mountain. At the same time, its dust color is red, which turns red when it meets water, indicating that it is rich in metal substances. Common patina includes yellow skin, green skin, bright skin, pit skin, layered patina, weathered patina and banded patina. It is more common that the skin is yellow agate, which is beautifully carved and very eye-catching.
