Auctions ▽Click here for President Nakazawa's channel    / @eco-material   This is Yasagure Metal! Thank you for watching. I'm conducting alchemical experiments to extract gold from junk computers and game software purchased from Hard Off and Book Off, and create ingots. We also investigate whether it's possible to make money from gold and silver by bidding on and appraising gold and silver products, antique coins, and silver coins listed on Yahoo! Auctions and Mercari, and selling them to precious metal buyers. Precious metals like gold are contained in everyday household appliances and smartphones, making urban mines all around us. This channel explores all aspects of gold, including gold refining using iodine tincture, the ancient cupellation method, precious metal melting and casting, and the creation of bullion and gold bars.
