เงินสเตอร์ลิงดีกว่าเงิน? ถ้าใช่, ทำไม?
Sterling Silver and silver are both used in jewelry. This is because they both are shiny, shimmering metals when they are polished, but the similarities end just there. Silver is not only metal but an element. Its chemical symbol is Ag, for Argentum, the Latin word for the metal. It is rare, but not as unique as gold or platinum. Along with gold and platinum, silver is estimated a precious metal. It is also a metal used in making coins, thus known as the coinage metal along with gold, ทองแดง, บรอนซ์, lead, สังกะสี, and nickel. Like pure gold, pure silver is too soft to be worn every day, so it’s usually alloyed with other metals to make it stronger. อย่างไรก็ตาม, fine, 99.9% silver is used for earrings, which aren’t subjected to the wear and tear, unlike rings or bracelets. To further help you to take the final decision about sterling silver and silver jewelry, let me offer my personal choice too.
Is refining sterling silver worth the time and cost or just melt into 925 บาร์?
Since it doesn’t melt until this temperature: 1763 degrees Fahrenheit,
(The melting point of silver is 1763 degrees Fahrenheit or 961.8 degrees Celsius.), it isn’t cost-effective to do it yourself, either further refine it or melt it down.
Silver is not at a high point in the fluctuating price of this volatile market, so hang onto it. for now !!
Check the spot price of silver, then see what is offered by a mail-in refiner.
If you try to sell it locally, say to a jeweler, they will only offer you 25% หรือ 40% of the spot price of the silver that day.. It would not make economic sense for them to buy it for what they are going to get from a refiner, remember.
