Olive, also known as olive. Olives carved into nuclear carvings are not ordinary olives, but "black olives" from the south, most of which are produced in Zengcheng, southeast Guangdong. Because of its large grain, thick meat, dense texture, dark color and high oil content, it is very smooth after playing, and it is easy to be coated. From yellow to brown and then to dark red, it will eventually play a shiny rosewood color.

Classification of olive stone raw materials

1. According to the shape and size of the nucleus, it is classified as 1. Large core, also known as single core, is generally more than 2 cm in diameter, which is more suitable for carving single pieces. 2. Small core: the general diameter is about 1 cm, which is more suitable for carving the chord head. 3. Round core: the shape is round, which is more suitable for polishing beads and carving a group of harmony. 4. Slender core: the body is long and narrow, suitable for carving nuclear boats and single pieces. 5. Strange nucleus: refers to a nucleus with a strange shape, such as "bergamot", which is a unique and unprocessed work of art..

Second, according to the classification of the nuclear edge: 1, three-flowered nucleus: Usually what we see is generally the triangular olive nucleus, also called three flowers. This variety is more. 2. Four-flower nucleus: relatively rare. One core with four flowers on all sides is very suitable for carving single-piece joys and sorrows. 3, two flower cores: very rare, two flower cores are relatively flat, very suitable for carving a single piece and two immortals. 4. Multi-flowered nucleus: also known as odd nucleus, it is the same nucleus as the "bergamot" mentioned above.

Third, according to the storage time of the core: 1, new core: refers to the olive stored within 5 years after picking and peeling, which is called new core. The new core is not suitable for carving, because the core has not been stored for a long time and the water in the core has not evaporated. If the work is carved immediately, it is very easy to crack. The new nucleus is yellow. 2. Old core: refers to olives stored for more than 5 years after peeling, which is called old core. The longer the olive pit is preserved, the better. If it is preserved for a long time, if it is not played with, the color of the core will turn red, so the works carved by the old core are relatively red. Because the nuclear has been placed for a long time, it has also adapted to the cold and warm changes of various climates, so it is not easy to crack.

The materials are clear, and the rest is up to the sculptor. It is difficult to judge the difference between personal vision and appreciation level. Be careful not to buy things carved by machines.
