Gold Is Gold

Regards,

Gold remains gold. Radiation has always attracted the attention of mankind. More and more high-glare radiation ray prices, the yellow color is more stable prices.

With the abbreviation Au, gold is now hunted humans. This shows that authenticity of the Au into the price difference with the Ag and Cu. The higher the percentage of Au increasingly expensive. Conversely, if Ag and Cu Au content dominate the price is definitely shrinking.

Various techniques are used to assess the quality of gold. Crushing, cutting and drilling had been abandoned. Modern techniques now known Assay techniques take over.

First use the technique to distinguish colors. Also known assay test using a special stone. Sample rubbed on a special stone. Various grades of golden plates in the same pads. Acid is used to determine the color. The rate difference is the lower 10-20 / 1000.

The second assay tests using XRF (X-ray flourescence) Take about 3 minutes. Accuracy of 2-5 parts / 1000. According to articles that are flat and large gold.

Third, test-fire assay techniques using the most effective and least damaging of gold. Accuracy of 1 part / 10.000. In this process the gold is separated from the alloy and weighed.

In any test, the gold content is worth.
