Master olivine! Which of these two cores is the best! ! Tell me why

Everything is fine, but I prefer the latter, which has a deep patina.

1. Nuclear tendon (flower): There are natural nuclear tendon dividing lines on the olive nucleus and its corresponding pores (commonly known as flowers), which can be generally divided into two-flower nucleus, three-flower nucleus and four-flower nucleus.

3. Nucleus: Olive nucleus can be divided into yellow fat nucleus, oil nucleus and iron nucleus. The yellow fat core is suitable for carving a single theme, and the iron core is delicate and ruddy. The oil core is not painted, and the iron core is topped.

There are new and old cores in a year, and the old cores have been fully dried in the shade for a long time, which is more suitable for carving.

Four. Carving method: According to carving techniques, it can be divided into vertical carving (round carving) and relief carving, including hollow carving and yin-yang carving.

5. Polishing: generally divided into polishing and knife marks. After polishing, the work is smooth and shiny. If there is a knife mark, it is not polished, but requires a finer knife work.
