The gold tester is able to determine the purity of the gold project

Every kind of gold has a different kind, and you need to know how to distinguish their true and false.
Gold items should be tested before they are sold. You can not venture to sell fake gold items, and there are customers or two people complain about fake jewelry. Anyone can happen. You can provide a fake gold without knowing it, but you can make sure that you get these items from the gold jeweler is real and avoid this dilemma. Whether you are a seller or a terminal consumer, you should know how to distinguish between true and false gold.

Skilled people can easily find a fake gold jewelry. According to these professionals, generally from the surface can be seen too shiny or too dark things may not be real gold. But gold can have different colors, from the brilliant yellow into pale yellow. Keep in mind that gold is usually alloyed with other metals to make it more durable. Gold itself is a very weak metal, it is easy to be scratched, but the amount of metal added, the lower the cost. There is now a way to determine the amount of gold in rings, bracelets, pendants, necklaces and chains. Calat is a unit of measurement, especially the specified gold to illustrate how much gold it contains. Clark is actually a proportion, not the actual weight or quality of gold. It tells you how much money is a piece of gold. All along, the gold price of a single gold coin is 1/24.

Through a simple understanding, it is often difficult to distinguish between different golden pieces. Buyers usually only rely on what the seller says. If the brand of the product is 14 karats of gold, a typical buyer simply takes it as 14 karats of gold, and if it is really 14k pieces, then no need to care. If you want to make sure that there is no better thing to do, but get a gold tester to check the piece. Today, you can rely on electronic testers to provide accurate readings, to provide you with instant karaoke reading. However, the electronic tester is too expensive to facilitate testing. The acid tester is offered at a much cheaper cost and is used by many jewelers and gold dealers around the world.

The acidity test has no unreliable results, and the principle behind it is to know that gold is almost non-reactive metals. Unlike most metals, such as iron, copper and silver, it does not react with strong acids. Thus, the acid actually determines the presence of other impurities, and the rate at which the reaction occurs determines how much impurities are present, thus indicating the purity of the sample or the amount of gold, if you also need to know more please click on the site.

What are the differences between the factors and characteristics of the gold tester?

Due to the special circumstances of the gold product jewelry products , the use of this method should be aware of and familiar with the following factors (the impact of these factors in different circumstances will have a great impact on the collection characteristics of line strength, and even cause justice) : A) the measured sample and the standard material and content contained in the element content is completely different; B) the surface of the test sample is coated or chemically treated; C) measurement time; D) the shape of the sample; E) the area measured by the sample; F) how much precious metal content; Gold testers test results usually require a comprehensive understanding of the different aspects of jewelry products, using different instruments, testers at different levels of quality, and testing the range of the proposed range. As the precious metal content decreases, the acceptable range will increase. The error range of the measurement result is 0.1% -3%.

Gold test method

Our daily life in the common inspection method is not Kaopu, then the gold test method is what ? 1, the density measurement method is simple and feasible It is understood that the density of gold at room temperature is 19.26 g / cm3 to 19.37 g / cm3, can be more accurate cups into a certain amount of water, and then into the gold bars into the water, measuring the new water, the sum of the two known gold bars The size, and then came to the density of gold bars. If the density is between the standard values, the gold bars are more likely to have a higher color, otherwise they may be doped. Common detection can be used density measurement method, this method is relatively simple, you can exclude some of the doped gold. This method can exclude most of the doped gold, but if the doping of gold through a strict proportion of the addition of other metals, it can not determine the iridium and tungsten, the proportion and the weight of gold and light similar to the measured density is not
