Recently, non-ferrous metals are becoming more popular. They attract attention with unusual combinations of shades, from which it is very difficult to look away. Today you can find products made not only from ordinary yellow, white or red gold, but also from black, blue and even green. Purple gold jewelry also looks interesting.
What it is?
Amethyst, purple or violet gold is an alloy, which includes not only ordinary gold, but also palladium and aluminum. As a result of remelting, a rather high-grade alloy of 18-19 carats is obtained, which is assigned 750 samples.
The process itself is quite difficult and time-consuming, and also expensive. After all, the melting point of each of the metals is different. So, for example, gold melts at a temperature of 1350 degrees Celsius. As for aluminum or palladium, a temperature of 600 degrees Celsius is sufficient for their melting. To get a beautiful lilac color, you must add at least 20 percent potassium to the alloy.
In the event that the percentage of potassium is lower, the precious metal will acquire an olive color.
Amethyst gold items were first discovered back in 1931 during archaeological excavations in Egypt. They were found in the burials of Tutankhamun. Many scientists worked on the secret of obtaining such gold. However, only the American physicist Robert Wood managed to unravel the secret. The alloy consisted of aluminum and ligature, but was very fragile. For this reason, they did not use it to create jewelry.
After several decades, the work was resumed. Patented Purple Alloy Recipe scientist from Singapore Lo Peng Cham. He worked on his invention for over 30 years. When the purple alloy appeared on the markets, it made a splash around the world. Developments were bought by the famous company Aspial, which became the main producer of amethyst gold. A sample of the Singapore alloy depends on the amount of precious metal in it.
So, on products you can find both 750 and 800 samples.
You can get purple gold in another way, which was used by scientists of the RAS. Thanks to the applied nanotechnology, the alloy turned out to be better and more durable. To create it, microparticles of gold and aluminum were used. In addition, Egyptian scientists also obtained purple metal using a laser.
