Mammoth extinction in more than ten thousand years ago, due to living in Siberia and Arras and other places, so their teeth are mostly preserved in Siberia and Alaska and other places in the permafrost. There is no big difference between the quality fossil ivory and the present ivory. And Mammoth teeth than the contemporary ivory density of high hardness, so Mammoth teeth handicrafts have a high appreciation, collection value, is the best of today's carving raw materials. It is scarce material, no regeneration, and dig a less one, so the value of their own high, the appreciation of space is also great.
First of all, from the species of mammoth raw materials to say, Mammoth teeth material classification of four categories: ice, frozen soil, soil materials, molars.
1. Ice material: mention the top material of the mammoth, have to say that ice material, ice material grade is very fine, not to say that the ice material must be the top material, we should be clear, generally familiar with everyone That is, 3A-class ice material, of course, there are better, for example, blue ice, the level of the material is more appropriate to do some of the carved circles like boutique or large, no cracks no spots, this is less , The material price is very high, not suitable for some ordinary small pieces, do the finished product is also very expensive, then sub-2A A class B and the like, are followed by the material of the degree of lubrication, With the level of reduction, loss and production will be more and more difficult. Some friends may see a lot of Mammoth material is very low price, feel cheap, but I tell you, you really get back to do, so you can use the material and then said, you will find the actual price of the material Is very high, because the more cheap, means that the greater the loss, especially the segment material, you do not know when you open the material will appear what kind of situation, Mammoth raw material is a big gambling, this is to With personal eyesight and luck, remember, Mo greedy cheap!
2. Frozen material This grade of material is much worse than the ice material, which is better than the low-grade ice material, but it is the same with the soil, the change is very rich, smooth and clean Much better than the average soil material, which is bald most like a material, although more crack, but the rich changes, each time to get the material produced by the performance of things are not the same
3. soil material is a kind of material is not willing to touch the head, although more rough, but the material with the production time is to let you cut people (waste throw is not not throw is not, will So that you have Cao Cao Cao Chouchao Yang Xiu repair the feeling), waste too much, basically there will be a lot of calcification of the part, the degree of lubrication is also poor, but the price is the lowest of these materials inside, The most rustic vicissitudes of life (here to add that the soil material is basically no degree of lubrication stratified calcification touched it is the endorsement of its endorsement, solidly have been attributed to the frozen soil, and that is the Northeast frozen soil, this Not used to know, hearsay it)
4. molars this and the previous three kinds of materials are not the same, because it is not an external teeth, it is the mouth of the Mammoth teeth, the texture is very different, to say fossil words, in fact, molars and mammoth bones is the real fossil , Basically all the petrochemical state, and this thing had the original hand over the finished product, because the production needs to the curing process, no equipment, and later not get, I need to note that this thing is a knife, especially with pattern steel, Is beautiful! Also molars of the material there is a relatively small, called the pulp material, this material curing very little, some more.
