Gold industry in Arab countries

           

   Gold is particularly important in Arab societies as a manifestation of the richness and nobility of origin.
Therefore,Craftsmen made a great effort in the manufacture and innovation of decorations, molds and shapes to present the newest always.

using of gold not only for women, but extended  to men who also usedIn decorating swords, daggers, sticks and guns, etc. .. Of the things that men likes to keep and proud of it.

The gold industry is one of the few industries that are low trading,and monopolize its secrets a few craftsmen.Therefore, they are reticenting their activities, and prefer not to inform others about the secrets of their profession.

The gold industry is one of the industries that are inherited from parents to childrenThus, it's difficult for strangers to enter the world of industry shaping gold.

Gold industry stages

The industry is divided into two parts:

The first is  manual, and the other is called casting wax.
  

Manual manufacturing method 

It's beginning with a 24 carat's alloy gold or went broke, the material was a slug it may have a specific mathematical equation is converted to either 18 carat or 21 or 22,The gold which is went broke have treatment after  knowing the caliber number because it might be less caliber.Then caliber is adjusted according to demand. For example, the manufacturing process of manual ring begins with pulling wires on the machine in certain sizes and then taking dimensions and lengthsfor the desired ring.then given to the technician entrusted with the work of the ring by the graphics described  to him who shall begin work after chipping on request.

The piece are then delivered to the technician who is form it according to the existing design he has.Technician can also be performed to form a piece of his innovations and creations without being boundExisting fees has.

Stage install stones

After it is detected on the segment to show any comments are going to install the stones stage.
In the course of all this always we clean piece and refined in every stage of the work.
Until finally produces a beautiful piece later go to the final cleaning stage,and used inChemical cleaning process then go to the vibrator machine which gives itthe desired color.
Yellow gold has many degrees of color where each color is associated with a certain caliber of gold. there is a certain color for caliber No. 18 and another one for caliber No. 21 and another for 22-caliber.
and recently entered a modern colors, which is used to paint gold, Unlike traditional colors.
Piece then go to the stage of final monitoring and seal according to caliber before delivery to the customer.
The seal reflects the level of standard of gold that was 18 or 21 and this expresses the ratio of gold to copper in the segment.The less the amount of copper that increased the value of caliber and vice versa.
Seals forms vary by the manufacturer.These seals are manufactured in Italy often,but there are also other countries doing this manufacturing.

Tools used in the manufacturing process manual

 There are several tools used in the manufacturing and hand-decorated piece like the chainsaw which is used for cutting gold, and scissors to form pieces on request.
In manual manufacturing pieces is not copied but it always is manufactured according to customer's request and desire.

Casting wax

 The second method of manufacturing gold methods are modern casting method or casting wax,and its synthesized phases are:
 First the basbakh and is the work of the so-called basic piece which made of silver.
Then after passing all the previous manual phases are carried over into the department of wax ,this basic peice must be at a very high degree of cleanliness and precision that will beCopied multiple times later,before installing stones.
In manufacturing method wax is placed piece in piston Rabr even be compressed thermally.
The graphics are printed on Raber and Raber is a specific type of sponge.
this processIt takes about two hours until the fees and formations are printed , then the piece go to Wax machine.  
 The machine contains amount of wax works thermally by electricity and through which convertGraphics to wax and then we clean wax accurately, then we make so-called tree wax.
Then this tree is cleaned with a chemical-packed to remove dust from above because the presence of a very small percentage of moisture, dust or salts greatly affect the standard of gold and reduce it. 

The next stage is the stage of furnaces:

The stage furnaces is one of the most reliable and most serious stages in the manufacturing process where  the gold oven first dissolving the wax which leaves a void within the gypsum, which takes the form of a tree and then go template to burning furnace which has a temperature of 750 degrees Celsius or more, where are drying template so turns to a piece of fire inside the oven on all sides.
After a period of 4 to six hours inside a convection oven we prepare gold to be poured or formed by oven to liquid temperature 1150 ° C, where we quickly move the template from the oven heat to machine suction quickly and accurately and we then pouring liquid gold in less than a minute so as not to cool the mold or gold, and then we vacuum rapid air untilGold down quickly and permeates all the blanks in the template.
And then cleaning the mold of gypsum in a certain way and abstracted tree which is then cut up the tree and dismantling of art.
 Then pieces go to the smoothing section to remove polyps then begin to clean up itTechnician before and after cutting the pieces are cleaned in certain acids to remove impuritiesOf gypsum and others. And then comes the stage of assembly and installation pieces stoneBy special machine and then be given final shape and color the final.
