Thank you for watching. I am conducting alchemy experiments by extracting gold from junk computers and game software purchased from Hard Off and Book Off, and making ingots. In addition, I also verify whether it is possible to make money from gold and silver by bidding on gold and silver products and old coins and silver coins listed on Yahoo! Auctions and Mercari, appraising them to see if they are genuine, and selling them to precious metal buying stores. Rare metals such as gold are contained in the home appliances and smartphones that everyone has in their homes, so urban mines are all around us. This is a channel where I try everything related to gold, such as refining gold using tincture of iodine, the ancient cupellation method, melting and casting precious metals, and making bullion and gold bars.
