Welcome to amazing creativity work ....................................... Gold testing in 3 ways. Gold checking in three methods. I will show you the video of the three methods of gold and fake gold tset. I am a goldsmith. I've shown a few processes on how to know gold and fake gold? Here we have frist shown how to identify gold with nitric acid in the technical process. We use it to purify gold with nitric acid. Nitric acid is very Dangerous acid. Nitric acid is to be used carefully. If gold is immersed in nitri acid,there will be no erosion. If the fake gold or copper or silver is immersed in nitric acid, it will be eroded. copper,silver,bronze etc.without gold,if the nitric acid is immersed in the acid,then the smoke of the yellow color will come out.But if there is gold,then there will be no yellow smoke.The simplest way to know the most gold is by nitric acid.If we convert gold to 14 ct,18 ct,22 ct to 24 ct,then we use nitric acid. Here is the second time I showed you how to check gold with Sulfuric acid in the technical process. Sulfuric acid is very Dangerous. This is the acid we use to clean the gold things. Here is the third method,how easily can gold and fake gold be recognized? Almost every gold shopkeeper here checks for gold in the third way. There is another way to check gold,however,is to go to the GOLD ASSAY CENTER. THANKS FOR WATCHING THIS VIDEO ................................. PLEASE SHARE THIS VIDEO EVERYONE.
