1, feeling

Just like distinguishing glass from hetian jade, the temperature of the hand is very important. Plastic ones don't like heat conduction because of structural problems, so they will feel warm in one minute even if it is a little cold at first. It feels sticky when rubbed. And ivory fruit, because of its natural organic characteristics, has fast heat transfer, which is always cold in your hand, has a texture when rubbed, is as comfortable as fruit, and will never stick to your hand.

2. Look at this texture

The texture of ivory fruit is definitely not as staggered as ivory rings. The pulp of ivory fruit is solidified by liquid. Therefore, the texture inside flows like thick yogurt, or like sesame sauce, chopsticks will have a soft track when they are stirred, so the texture on large sections is random and absolutely irregular. There will be a small parallel road at the tiny edge or cutting place, that's all, there is no other texture.

3. Heating method

Some friends say that hot needles are used, and some suggest burning, all of which are heating methods. If it's a small thing, set a fire. If it's a big deal, ask the boss what to do if it's fake after the fire. When the boss sees it, he usually tells the truth.

Maintenance method of ivory

1. Ivory is an organic matter and a finely crafted product. Some varieties, such as flowers and small works (reliefs), still pursue exquisiteness in workmanship, even more exquisite, and are afraid of falling, squeezing, bumping, burning and flooding (ivory itself is not afraid of water, but it is afraid of water at the painted place), and it is also easy to be oxidized under dry climate conditions. So daily protection is very important. Generally speaking, ivory carvings should be preserved in a relatively humid environment, and it is easier to preserve in the south than in the north. The general temperature is 15-25℃ and the humidity is 15%-65%.

2. ivory carving is afraid of direct sunlight, which will cause local deformation, fracture and discoloration of ivory carving. In addition, the newly colored ivory is white. Although it has been painted with paraffin wax, it is necessary to avoid direct sunlight to avoid yellowing.

3. Ivory carving is dirty and should be treated differently. Old color paintings can't be stained with water, and can only be wiped with a soft cloth or a soft brush; Smoked yellow can be wiped with a wet cloth, as long as the hair, eyes and other places are not wet, you can also rinse with water. Generally speaking, the old color work and the smoked yellow work are dirty and need not be washed. It is good to wax them again. New colors can be divided into semi-color and full color. Full-color works cannot be washed, and half-color works can be washed as long as there is no water in the color. Generally, it can be wiped with fine white cotton cloth. If you want to dry naturally in the shade after washing, you'd better cover it with a white cloth and don't let the wind blow. When it is dry, wax it again. Wipe with a brown brush dipped in hot paraffin, and finally wipe off the excess paraffin with a fine white cotton cloth.

4. Every ivory carving ornament must be equipped with wooden pedestal and outer packing box before leaving the factory. The outer packing box is generally made of thick cardboard with brocade forging outside, which is called "brocade box". The ivory carving ornaments lie on the soft bag in the brocade box, and there are two or three cardboard clips, one of which is stuck on the wooden seat, and the other two clips are stuck on the thick and affordable parts of the ivory carving ornaments, so as to ensure the safety of the ivory carving ornaments during transportation, handling and storage. Some ivory carvings are erected in brocade boxes, but all of them are outward. Keep the original storage state every time you put it away. The insertion position of each clip cannot be changed at will.

5. Wooden pedestal with ivory carving ornaments. Except for the shape of individual ornaments, bamboo nails are usually placed at the bottom of ivory carving ornaments to connect with wooden seats, so the wooden seats are connected with ivory carving ornaments.

When moving the ivory carving ornaments, the part you reach out and hold should be the middle part of the ivory carving (the closer you are to the center of gravity, the more stable you hold it), which is a relatively solid part (that is, the part that is not popular with the sculptor). It is best to hold ivory in both hands, not wooden seats (except for large and medium-sized ivory carving ornaments). Because the wooden seat is worthless, even if it falls, it is nothing. It is the worst way to move ivory ornaments only with wooden stands (except for large and medium-sized ivory pieces).

6. There are two bones outside the brocade box, which can be inserted into the cloth button to fasten the lid. Every time you put the ivory ornaments into the brocade box, you should insert the bones properly, so that even if the box falls down carelessly, it will not damage the ivory pieces.

Sometimes I buy ivory tablets without brocade boxes. Wrap multiple layers with soft paper, and you can carry it safely.
