How to check the silver purity at home?

Every person knows the value of silver or gold in terms of cash. In the current disturbing economic periods, you can rely more on the value of such commodities than the cash balance locked in your bank accounts. Having a stock of silver with you as well as knowing the time period of selling it to the online metal stockbroker could be a great method to control your cash flow and also to make certain quick money.

However, in what way do you know that the silver which you are having at home is pure? No person can easily detect the purity of silver with his/her open eyes as for doing this you have to be an experienced jeweler or dealer of silver. But, there are still few ways through which the purity of the silver can be checked so that you do not get trapped in this fake metal web.

The following are the few top methods through which you can check the purity of the silver so that you can easily compare between the real and the bogus metal:

Step 1: Touchstone

The first method in this list is touchstone which is being used from past many years for checking the purity of the silver metal. It used to prepare from a piece of heavy slate over which the silver product was scrubbed. The color of the resultant bar was matched to the outcomes from recognized metals. So, if the color was same, then more analysis could be commenced by smearing “Aqua Regia” (a solution of Hydrochloric acids and Nitric acid).

Step 2: Magnetic

Silver metal does not comprise of magnetic properties. Hence, if the silver which you are testing is having magnetic properties then it might not be pure silver. But, if your product is not magnetic, then this merely verifies that it can be silver – plated or silver.

Step 3: Sound

Silver has a distinctive ringing sound when dropped onto a hard surface or struck with a small hammer. Specialist equipment is sometimes used to analyze the specific harmonics however if you make a clean strike of the metal and there is no ringing sound then this is the first alarm that what you have may not be silver.

Step 4: Chemical Analysis for testing

The test that is normally used by people and the jewelers is to rub on a “Schweitzer’s” solution (comprises of potassium dichromate and nitric acid) with a cloth either straight to the silver or to an adequate sample taken out from the portion by filing or penetrating.

But you have to remember that the solution needs to be applied on the smaller area of the silver so that it cannot be visible easily as it might leave a darkish deposit on the surface. If your metal is pure then the color of the solution will become dark red. However, this test is not 100% accurate because you cannot judge the purity of the acids that are used in this process.

Step 5: Hardness as well as malleability

Silver is comparatively malleable and soft. Hence, if your bend your silver product and it gets bend easily, then this means it is a pure metal. But if you find it difficult to bend the metal, then it is not silver for sure.

Step 6: Hallmarks Assurance

Hallmarks are engraved on the silver items and offer a legal guarantee or assurance for the amounts of purity for diverse categories of silver. For example, in the case of genuine silver, the percentage of purity by hallmark is 92.5%. There are some companies that give the legal and technical explanation about the purity of the silver by way of certification.

Step 7: Mass spectrometry

This is a method for examining the molecular arrangement of a compound structure. For valuable metals like silver, ICP-MS (Inductively coupled plasma – Mass spectrometry) is utilized to identify and isolated the ions of the silver. Due to the accuracy offered by this method, it is also commonly used by analyzing offices.

Step 8: Fire Assay

One more method utilized by the metal analyzing offices is the melting of the sample which is taken out from the silver. After this, the metal is also chemically examined.

Step 9: X-ray fluorescent gun

This gun is a Niton x-ray fluorescence analyzer which is a handheld device. It is used in reducing the x-ray pipes in a thermoelectrically ventilated gauge with the help of an onboard data regulator which also examines its consequences that are showed on the screen. This is a fast and fairly perfect method for testing the purity of silver, however; it does not possess a very deep infiltration and hence can be deceived by a heavyweight silver plate.

Step 10: Explicit gravity

The last method is checking the purity through the explicit gravity. The explicit gravity of the silver is 10.49 and its dimension can be taken by utilizing the numerous water shifting techniques.
