Imitations of amber are usually made from Copal, plastic, celluloid, glass and synthetic resins. Often a fake put internal inclusion, simulating a fossil of an insect or a leaf of an ancient fern, which should increase the value of the stone.
To identify a fake note not the product (for example, in place of the holes of amber beads). Fake amber is easily crumbles and breaks off. If you heat the crumbs the product of artificial material at the tip of a knife, they will emit the unpleasant characteristic odor.
Another way to check the authenticity of amber is to put it in strong brine, where it needs to stay on the surface, while in pure water it sinks.
A professional with special equipment, will reveal the imitation is even easier – natural amber under UV light, emits blue light.
Young or "immature" amber called Kopal. Age digging is usually not millions of years, but only a few tens of thousands. Modern technologies allow to dig, identical to natural stone, resin trees.
In order to distinguish Copal from full amber in an inconspicuous area of the product, apply a drop of alcohol and apply to this place the finger. The sticky surface will give digging. The second method of detecting dig – apply for a couple of seconds a drop of acetone on the surface of the inspected material. If in this place there is a spot, we are dealing with Kopal. This method should be used with caution as prolonged exposure to acetone even natural amber can remain the spot (it is removed by polishing).
Keep in mind that counterfeiting of plastics should be distinguished from natural pressed amber. Only a small fraction of produced natural stone has large dimensions; a large part is a small pieces of stone, were treated by extrusion. Upon closer examination, this amber seems composed of small pieces, but it's still a natural material with inherent natural properties.
Advice 2: How to determine the authenticity of amber
Fossilized millions of years ago resin gave people "a solar stone" – amber. He is very handsome and has healing properties, so the demand for products made of amber has always been high. One of the serious problems of the amber market, many counterfeits of glass, plastics, synthetic resins, and also imitations from ambroid, Copal and Kauri. To determine the authenticity of amber absolute accuracy is possible only in laboratory conditions. However, there are several simple ways available to everyone.
External midnineteen inspect the product. To distinguish the amber is rich play of colors and unique pattern. Too uniform color, the presence of a large number of air bubbles and "lenses" suggests that before you imitation. Inside pressed amber (ambroid) are usually well differentiated structure of flow and elongated in one direction, the air bubbles. In natural amber, they must have the correct spherical form.
Electricityprices a piece of amber on wool or fur. It should alectrosaurus and begin to attract light objects: thread, pieces of paper etc. However, some types of plastics are also electrified, but the effect is less pronounced. If the electron is completely absent, offer you a clear forgery.
Will prototiposite sample in concentrated hydrochloric acid solution (8 – 10 teaspoons in a glass of water). From amber of very low density (average of 1.05 – 1.12 g/cm3). From plastics, synthetic resins, and especially glass it is much higher. Therefore, true amber will float to the surface, while fake amber will sink. However, if the product is enclosed in a metal frame, to use this method will be difficult.
Tapahtumasta to the surface of the stone lit a match. Natural amber will emit a characteristic smell of rosin, plastic fake – unpleasant chemical smell.
Groupcalendar is a very fragile material. Try to scratch the surface with a sharp knife. If this produces shavings, before you synthetic polymer. Real amber will crumble.
Luminescence whether the seller will be delighted with your attempts to burn or scratch the product. But if the cashier has an apparatus for checking the authenticity of banknotes, ask to enlighten stone with ultraviolet light. The amber will begin to luminesce to provide light predominantly blue shades. Most plastics in ultraviolet rays does not glow, digging becomes white.
Kopal, Kauri"Young" kopelove fossil resins and modern Kopal, derived from resin of pine-Kauri, much softer amber. Click on the product hard. If it is going to be a trail before you dig. Kopalova resin is not electrified by friction, when heated emit an unpleasant medicinal smell. Unlike natural amber, they dissolve into the ether. Drip the ether on the surface capolavoro sample: it becomes sticky, and then turbid.
