① Newly-started ivory products: use the maintenance oil pan once every morning, noon and evening for half an hour. After that, the maintenance cycle can be gradually shortened and reduced.

(2) After half a month: first wipe it with cotton cloth for half a month, once in the morning and once in the evening, 20 minutes each time, for half a month.

(3) After half a month's kneading period: playing with hands for half a month (hands can not only play the role of fine grinding, but also keep warm and moist, and sweat and grease secreted by hands can also accelerate the progress of playing with ivory products). Methods: Wash and dry your hands, and rub the mammoth ivory products evenly with your thumb and palm with three forces in turn until your palms are wet and sweaty. It's still 20 minutes in the morning and 20 minutes at night.

(4) repeating the above steps until the patina is formed. When not playing or wearing, the mammoth ivory products should be evenly oiled and maintained, then put in a sealed container and placed in a cool place.

Maintenance:

1. If you have personal ornaments of ivory, you must take them off when you take a bath, because ivory will crack and change color once it is put in hot water for too long. And it's best not to drop it, because it's easy to be damaged, so play more when you have time.

Don't let ivory stick to irritating liquids such as detergent, because the surface gloss will darken and the color will turn black. It is normal to play for a long time. How should ivory be maintained so as not to age and turn yellow?

If it is an ornament, there is no way to stop it, because human sweat will make it yellow. If it is decoration, you can find ways to block the air, such as covering it with a glass cover and putting some water to prevent cracking. Ivory is fragile, please take care of it. It is not recommended to maintain ivory with oil. If it is dirty, you can use a toothbrush dipped in toothpaste to clean it, but the time should not be too long, otherwise it will crack easily.

Taboo:

Mammoths avoid water in their ivory. Basically, all kinds of dental materials should not be stained with water, and teeth are corrosive to some extent. So mammoth ivory does not need special cleaning. When you find that it is really necessary to clean, you just need to dip a cotton swab in a little water and get a little wet, then wipe it and dry it with a dry cloth.

Mammoth ivory tries to avoid temperature difference and blowing, especially in autumn and winter. The temperature difference is large, and it is hot in the south and cold in the north. In the long run, it is easy to crack, so we should adapt it and don't rush to play, which will cause irreparable losses!

Second, if you don't play for a long time, you can put it in a sealed bag and put it in a relatively constant temperature and windless place, and then pay attention to the environmental humidity when you take it out next time. Avoid inadvertently causing it to be hot and cold, hot and cold, and crack!
