It is in the air we breathe, soil, common beauty products, smoke, fertilizers, foods, gasoline, pollution…и т.н.. The list is so long there is no way to cover it in a blog, but trust […]
There are two commonly used tests to determine the silver content in an alloy. X-ray testing is non-destructive but requires special, expensive equipment.

Jewelry sold as just “сребро” is a bit of a mystery. The term is thrown around in the market as a color descriptor, especially in fashion. Обаче, in the jewelry trade, items should be clearly identified as a specific standard quality. If not, it is unlikely that the silver alloy is of very high […]
