Silver, Gold and Rhodium

In this post I will talk about an issue that confuses a lot of people with regard to silver, gold and rhodium plated and bathed semijoia. What is the difference and the process used? The process that is semijoia (or other metal adornment) with a noble metal is known as electroplating. This process used in semijoias has two purposes: the first is to protect the base metal from corrosion and oxidation, and the second purpose is to provide a finish with more beauty, color and brightness to enhance even more the part.

Procedure for the Silver, Gold and Rhodium

Galvanizing or electroplating is to immerse the semijoia (usually made of silver, copper, cadmium, Tin, Palladium or nickel) in an electrolyte solution with the presence of the desired metal. For example, the base metal is dipped in a solution of gold salts * that is inside a container (tank) with an anode (carriers of electrical current). This tank has a voltage regulator that must conform to the workpiece surface and with the kind of metal that will receive the bath. Iron is a metal that can not receive this type of bath. With the metal-based dips a gold bar. Under these conditions, the gold is carried by the fluid and deposited on the piece to be golden. As long as the semijoia is dipped in the solution and the thickness of metal deposited on the surface of the part, determine the type of bath. It is important to know that “too long” is not always brings the best outcome and that a piece can go through more than one type of bath. Before the bath, it is necessary to give a good Polish in part or if you have a matte finish (matte, sandblasting, diamond wheel), it must also be fosqueada before. For this procedure to be completed with quality it is recommended that the professional galvanic branch is well trained and that the products and machinery are in very good condition.

* In the case of gold, the solution is made with a gold salt room, more 1,000 ml of ionized water.

** The preparation of rhodium solution is made with 100 ml of metal processed more 900 ml water.

Types of Shower

There are baths with yellow gold, rose gold, red gold, white, black rhodium rhodium rhodium chocolate, old gold, silver, old varnish, among others. Depending on the time of immersion, the layer on the surface can be more or less thick. Good gilding have thickness in the order of 0.02 mm (it is said 20 thousandths). Pieces with thicknesses of less than five thousandths are considered jewelry and low durability. It is not easy to differentiate a semijoia bathed of a veneered semijoia. The difference of a veneered semijoia and bathed is that one piece bathed receives only one bathroom for seconds of the noble metal (not present), while the semijoia veneered receives multiple layers (thousandths) of this noble metal, i.e. several baths. For this reason, there are several semijoias prices between one shop and another, because this value added depends on how many layers of noble metal base is coated.

Care and Conservation

It is important to know some tips for the semijoias especially for those who use them daily. The semijoias can last for many years with appearance of new if subjected to basic care of use and cleaning.

-Wash your semijoia with fresh water and dry with a hair dryer (helps to restore the brightness) before holding it, especially after using it on a hot day, remembering that the salt present in sweat is the worst enemy.

-If the part is of smooth surface, use a soft and dry flannel to Polish.

-Cosmetics for hair and strong have substances that harm the gold layer, avoid contact.

-If you make use of perfume, wait to dry before putting on your semijoia.

-Remember to remove your semijoia before entering the pool or in the sea.

-Save the pieces individually avoiding the friction between them.

-Caution when using semijoia in your household chores or sports.

– Take special care with natural or synthetic stones, as they may break with impacts.
