How to identify ivory, the easiest way to identify ivory

I'm writing this ivory to you in my hand.

White with a weak grayish yellow. There are weak lines inside, and the color of the lines is slightly yellow compared to the areas without lines.

The whole color is soft white with a hint of grayish-yellow.

The sound was the sound of bones, and the sound of ivory and ivory colliding was much more brittle than plastic, but it was not the sonorous sound of metal, and that sound was indescribable.

It's better to have relatives bring it to you from places like Angola, so that you have that rough ore feeling.

The color becomes softer and softer, and like the flawless jasper produced in Manas County, it can trap people in it. Looking at that kind of white, people's impetuous hearts become pure and natural. No wonder so many people use ivory to commit crimes.

First, look at the overall color of the ivory. Real ivory is usually white in color, with occasional yellowish tinges, and has an excellent color. The older the ivory, the more yellow the surface will become, and the color will gradually change from pale yellow to turmeric, dark yellow, or even light brown.

Second, look at the fracture lines of the ivory. The older the ivory, the darker, longer and longer the finch on the ivory, which in turn cracked. Fake ivory, the surface is dull, and the cracks in the finch are unnatural.

Then, feel the heat transfer properties of the ivory. Real ivory has a good thermal conductivity, and the user can hold it with his hand for a while, and if he feels a significant heat, it means that the ivory is real.

Then identify the feel of the tusks. Because the texture of ivory is fine, the specific gravity is slightly larger than that of bone, so it usually feels good to the hand and does not flutter.

Look at workmanship. Bone products do not take a lot of effort to carve, and are generally relatively simple and crude. Ivory products, on the other hand, are mostly complex and delicate.

Finally, take a closer look at the skin and core. Although the outer skin of ivory has a layer of tooth skin, although it is all ivory, the texture of the leather is much rougher than that of the core material, and the texture of the tooth core is delicate and smooth, and the tooth skin turns yellow quickly during the end of the tooth skin.

Five ways to identify real and fake ivory. 1.Smell the smell:

Real ivory products smell odorless, while fake ivory products often smell like smoke. 2.Weighing weight:

Ivory is dense, and for ornaments of the same size, real ivory weighs more than bone and artificial ivory. 3.View Lines:

The real ivory products have fine textures, grid patterns in the cross-section, and wave patterns and herringbone patterns in the longitudinal section. The cross-section of bone products shows intermittent annual rings; The deliberately made tooth patterns of artificial ivory products (synthesized by chemical processes) are rigid and sluggish, showing regular parallel lines, which are clearly different from the natural herringbone and reticulation patterns of ivory. 4.Look at the color and shine:

Ivory jewelry is often ivory-white, giving people a moist and white feeling; Most of the bone carved ornaments have to be bleached, which makes them dry and unnatural, colored and dull. 5.Product workmanship:

The real ivory ornaments are more elaborate, and have both form and spirit; Bone carved ornaments are mostly rough in workmanship and weak in knife skills; Artificial ivory ornaments often leave traces of molds, there are. Full text.

Summary. Hello dear, the easiest way to identify ivory:1

Observe the texture: ordinary ivory has a delicate texture and coarse grain, which cannot be easily seen; Artificial ivory has a rough texture and coarse lines, which cannot be easily seen. 2.

Check the gloss: the real ivory gloss is very good, oily and shiny; Ordinary ivory feels drier and less oily than ivory products. 3.

Check the color: the original color of real ivory is ivory white, and ordinary bone products need to be bleached; The bleached color does not have an oily feeling.

Hello dear, the easiest way to identify ivory:1Observe the texture:

Ordinary ivory has a delicate texture and coarse lines, which cannot be easily seen; The artificial ivory has a rough texture and thick lines, which cannot be easily seen. 2.Check the gloss:

Real ivory has a very good gloss, oily and shiny; Ordinary ivory feels drier and less oily than ivory products. 3.Check the color:

The original color of real ivory is ivory white, and ordinary bone products need to be bleached; The color after bleaching is not as oily as it is known.

I just don't know how to look at it, is there any other way.

The easiest way to identify ivory is to look at its texture and color. Ivory has a distinct texture, often with thin lines or spots of black or brown, which are traces of pipes and blood vessels in the tusks. The color of ivory is usually creamy, beige, or yellowish, and is not too bright or too dark.

In addition to observing the texture and color, ivory can be further identified by:1Use a needle or knife to gently scrape the surface of the ivory, if the scratch is not deep, the surface is slightly uneven, and there is no exudation, then it may be ivory.

2.Smell the smell of ivory, which has a peculiar smell similar to singeing, but not pungent. 3.

Touching the surface of the ivory with your hand will give it a warm feel, not as smooth or rough as plastic or other materials. 4.When an ultraviolet lamp is used to irradiate ivory, real ivory will fluoresce blue or white limbs, while artificial ivory will not fluoresce.

It should be noted that there are other more professional methods to identify ivory, such as testing the density, hardness, elasticity and other indicators of ivory. However, these methods require specialized instruments and techniques and are not suitable for operation at home. If you need a formal accreditation, it is advisable to seek help from a professional institution or museum.

Summary. Hello dear has helped you to find the results; The easiest way to identify ivory is through the following steps:1

Observed color: Ivory is usually creamy, yellow, or brown. If the ivory appears red or blue, it may be dyed and not really ivory.

2.Observe the patterns: Ivory has unique patterns and patterns, which are usually irregular, but there are also some regular patterns.

If the pattern is too regular, it may be an imitation. 3.Smell the smell:

Ivory has a peculiar smell, similar to tobacco or camphor. If you smell a different smell, it may be an imitation. 4.

Touch surface: The surface of the ivory is usually smooth, but there are also some bumps, which are characteristic of the ivory itself. If the surface is too smooth, it may be an imitation.

It is important to note that the purchase and sale of ivory is prohibited due to the protection of ivory, and the purchase and use of ivory products should be avoided. I hope I can help you and wish you a happy life <>

Magnify five-fold. Target**.

Hello dear has helped you to find the results; According to the judgment of ** boy, the first Tan can be an ivory wood to the eye hand string Nian Qin, because you can't see the real thing, you can't judge accurately. I hope I can help you and wish you a happy life <>

Ivory wood is something.

Hello dear has helped you to find the results; Ivory wood, also known as ivory tree, black bark, Ryukyu ebony, is an evergreen tree of persimmon family, born in the coastal broad-leaved evergreen forest, the bark is hard and black, mottled with multiple circles or ice-like cracks, like the skin of an elephant. The leaves are alternate, obovate, entire, thick leathery, densely branched, soft and easy to shape. dioecious, axillary, milky white, open in late spring and early summer.

The fruit is oval, the first tan is ripe in December, the ripe fruit turns from orange to purple red, and Ling Nianqin is lovely. The ivory tree is an excellent bonsai tree species for viewing leaves, flowers and fruits. I hope I can help you and wish you a happy life <>

At present, the conventional methods used in ivory identification are to use instruments to analyze the elemental composition of ivory and use the texture structure of ivory to determine the species.

Instrumental analysis mainly uses scanning electron microscopy to quantitatively analyze the inorganic components of ivory, for example, the main inorganic components of African ivory are calcium (about 36%) and phosphorus (about 18%), or infrared spectroscopy is used to quantitatively analyze the organic components of ivory;

Due to the high phosphorus content of ivory, it can also be analyzed by phosphorescent or fluorescence spectroscopy of ivory using Raman scattering instrument. Instrumental analysis is expensive and suitable for trace physical evidence.

If the ivory has a certain volume and a clear texture, such as for handicraft inspection, it is best to use a low-cost and fast texture inspection method.

1. Procedures for ivory examination.

1. Extract a trace sample powder, and smell the burnt protein by alcohol lamp roasting as animal products; The smell of coal is plastic.

2. When the short-wave ultraviolet lamp is excited, a hazy blue fluorescence appears, which is ivory; No fluorescence or other color fluorescence is false ivory.

3. The longitudinal section of ivory presents a set of longitudinal textures that are parallel and directionally distributed, have a certain distance spacing, and are coarsely subdivided and uniform, and the cross-section is an arc-shaped cross diamond texture (the big horn of the rhombus) 115, which is called the Letz texture line, which is a unique feature of ivory.

From the surface of the real ivory, you can see that there are typical cross-type checks, and the size of the checks is a little regular.

Looking at the inner layer of the ivory, you can see concentric ring-shaped growth lines similar to trees, but this distinguishing feature is only valid when identifying raw materials or sources.

Ivory has a typical creamy white color, and the general bone meal pressed products are mostly miserable white.

How to distinguish the real from the fake.

1. Hand feel. Just like distinguishing between glass and Hetian jade, the temperature at which you get started is very important. Plastic does not like to conduct heat due to structural problems, so if you hold it in your hand, even if it is the current weather, it will start to be a little cool, and you will feel warm after a minute.

It's a little sticky, sticky, and sticky. Due to its natural organic characteristics, ivory fruit transfers heat quickly and leaks the slag and leaks the ridge, which is always cooler in the hand, and has a texture when rubbed, which is very comfortable like a fruit, and will never stick to the hands.

2. Look at the texture.

The texture of the ivory fruit is definitely not staggered like the ivory rings. The flesh of the ivory fruit is formed by liquid coagulation. So the texture inside has a sense of fluidity like thick yogurt, or to use an analogy, like tahini, there will be a soft trajectory when the chopsticks are stirred, so the texture on the large section is random and absolutely irregular.

There will be very fine parallel paths at the small edges or passes, and that's it, and there will be no other texture to speak of.

3. Heating method.

Some friends say to use a hot needle, and some suggest fire, both of which are heating methods. If it's a small thing, burn it, if it's a large item, or ask the boss, what if it's fake after the fire, the boss will see that it's going to be real, and he will generally tell the truth.
