The Fatwas and the Sandalus and the Miska
In 1907, the American scientist, Belgian national Leo Buckland, announced his invention of a new, easy-to-form, heat-resistant and combustion material, phenol formaldehyde. In 1910, the material was commercially manufactured by American General Bakelite Company, Tejari is Bakelite, and the production of the company was limited to 4 or 5 colors, all of which were not transparent (black, red, brown, green), then the material became popular and sought in the market which encouraged the world to develop. For the manufacture of Baklite transparent materials and many colors, and called a new trade name, "Alcatelin", and then cooperation P people later to be called Balfatouran.
Or "Cherry Amber Bakelite". This is his scientific name, and the name Faturan is Greek or Greek. The two bills are considered to be the most expensive and manufactured raw materials and are used to decorate jewelry in Europe, Japan and Russia and make the swimming pools. The two invoices are chemically composed of two main substances (phenol and formaldehyde) as well as some other chemicals.
There are many controversies about the manufacture of the two invoices, many of the fans of the world and collectors of collectors differ in the origin of the installation of this strange material, but they collect as a precious and rare material, especially the German original, which stopped manufacturing since World War II, Because it is simply that no one has been able to reach a secret that has been cooked despite their analysis and knowledge of its components. Therefore, the quantity of the world's circulation is constant and does not increase, which makes its price increase year after year.
One chemist who specializes in polymer manufacturing was asked: Can we not manufacture a substance even though we know its chemical composition? He replied: It is normal to be unable to make a material even to know the composition; otherwise why the taste of food in restaurants differs from homes, although the method of manufacturing and raw materials one?
Phenolic plastics are now manufactured in some countries of the world. They are similar to the original two bottles, in terms of smell and some other specifications, but vary in quality from one factory to another.
Sandalus is a term used for all non-natural industrial materials (one of the members of the phenolic plastic family), the most famous of which is the German Sandalus and the Turkish Sandalus, although it is manufactured in many countries of the world, but we go back to say that the quality of manufacturing varies and therefore its price varies.
Al-Mustaqka is the third species and has the opacity of its ore and its many colors, especially the yellow and its degrees, and there is no transparent ones ... Butterscotch Amber Bakelite is the scientific name of the material. The word "musket" is also Greek or Greek. Burning and itching in the nose.
Misketa .. or as called by foreigners Misketa .. is a material made of modern glues and falls under the umbrella of Amberweet Amberoid or Amberweet .. This umbrella, which included everything similar to amber in terms of color and smell.
Sometimes the glues of some trees in this article may enter as catalysts or as a basis for their manufacture after being chemically processed and augmented with additions to certain types of plastics.
Here, it is necessary to differentiate the origin of the label Valmskita or Almtakp has nothing to do with the food-flavored delicacy, which is a natural substance that appears in the form of tears in some trees of the Mediterranean and used to enhance the flavor of food.
In general, there are many types of mesquita, pteran and sandalus, and the old materials differ from the new materials. Ancient materials are German, Czech or American origin and modern ones are Turkish, Egyptian or Asian in general. However, the "ratios" and "standards" in the manufacture of these "mixtures" are different .. For this reason we see a difference between two spices of the same material .. This also shows the difference in smell or oxidation in terms of speed or slow color change, The new materials are the main difference between the old and new materials.
In order to distinguish between the masculine and the phylorus, one can use two methods:
1 - Burning a small pin by heating it to redness and then biting one of the grains in the swimming pool or under the witness and then smell the smell immediately, and of course must be the sense of smell intact.
2 - Put the sprig under a stream of hot water and test the smell emitted from it. If the smell is similar to "Shata", which may cause the itching of the nose is doubtful .. But if the smell like the smell of medicine or ink is mixed with the smell of pine is Vtoran .. And to differentiate more between the Faturan and Mstakp: Filaran has a more attractive luster and translucent transparency.
