Ways to Test the Purity of Gold

Different methods are adopted to test the purity of gold. Karat is the measurement used for measuring the purity of gold. Pure gold is usually known as 24 karat gold. Before the invention of gold testing machine, the purity of gold was tested using porcelain, glass and magnet. The use of porcelain to test the purity of the metal-gold included scratching the sample metal on unglazed porcelain, if the color of the streak is yellow, it is pure gold.

Similarly the use of glass to check the purity of gold included scratching the sample metal on a piece of glass, since gold is known to be softer than glass, it should not leave any mark on the glass when scratched.

Magnets were also considered as the ancient Metal Testing in Chennai. This simple test involves holding the sample metal near to the magnet, if it is pure gold, the magnet fails to attract it. All these tests mentioned above are different kinds of initial tests which do not prove the content of gold present or the exact amount. Since the gold testing machine was unavailable in those days, most of the people resorted to such methods which have become obsolete today.

Understanding Total Polar Compounds in Oil: A Key Indicator of Oil Quality and Safety

In the food and oil processing industry, maintaining the quality and safety of edible oils is crucial. One of the most significant indicators of oil degradation during use, especially during frying, is the formation of Total Polar Compounds (TPCs) . These compounds play a vital role in determining whether the oil is still suitable for consumption or needs to be discarded. What Are Total Polar Compounds? Total Polar Compounds are a group of substances formed when edible oils are exposed to high temperatures, such as during deep frying. Over time, heat, oxygen, and moisture cause the oil to break down, resulting in the formation of polar substances like oxidized triglycerides, free fatty acids, mono- and diglycerides, and polymerized triglycerides. These compounds increase with repeated oil use and indicate oil degradation, reduced nutritional value, and the potential formation of harmful substances. Why Is TPC Measurement Important? Monitoring TPC levels is essential for both food safe...
