gold
It is one of the precious metals, as it is used extensively in the manufacture of jewelry, in addition to some other industries in the cosmetic and medical field, and others, and it must be noted that it goes through many processes until it reaches its formable form, and the most important of which is the melting or smelting process, which requires identification The gold standard, and in this article we will introduce you to this process.
How to melt gold
Gold dissolving tools
- Melting furnace: This furnace is made of fiery stone, and it is ignited by means of a tube connected to a gas bottle, and it is possible to use an electric furnace, but with the same specifications as a stone furnace.
- Melting crucible: has a semi-conical shape, has a flat base, and comes in many sizes.
- Casting molds: They are of various shapes and sizes, some of which are wide and some are narrow.
- The handle is a tool used to hold the melting crucible, as it helps to pour the melted gold.
- Substances that help in the dissolution of gold: such as bauxide.
- Carbon rod: it is used to stir dissolved gold in the crucible, to obtain a homogeneous solution.
The process of melting gold
It is inserted into the furnace, where it will be transferred to the melting pot, then some auxiliary materials are added to dissolve it, such as oxide, and stirred with a carbon rod.
Gold casting process
It is poured into special molds using the handle, through which the melting crucible is caught, then set aside until it cools.
Gold rolling process
Rolling machines are used, which are divided into two types, but it can be combined into one machine, which is billet and wire, as it reduces its thickness according to the required measurements, and it must be noted that there are many other machines that reduce the wire diameter to the lowest sizes, which It reaches the noodles, and this machines are known as disk machines, and it is recommended to take into account heating from time to time during this process, to obtain the required degree of ductility.
Gold crafting process
It is the final process, through which a usable form is obtained, and the formulation process differs depending on the product to be manufactured and the shape, as each product has a special way of implementing it, and it must be noted that there are many tools and materials needed during the drafting process, such as scissors Dedicated, multi-head gas welding machine, hammer, ruler, saw, hand dies, coolant used for smoothing, liner bedding, acids used to restore its natural color after the manufacturing process, such as hypochlorous acid.
