Gringgotts #1 is the simplest, and safest treatment for Bronze Disease available. It does take longer than ome other methods, but remember that it has taken centuries of the conditions to develop that create BD, so do not expect a cure over night. A little goes a long ways, a tablespoon in 2 cups of water or 10 grams in 700 ml, is all that is needed for a batch of coins, several may be treated at the same time. You may experience a color change from green to brown, that is a reaction of the copper carbonate, but is natural. If you have purchased coins from anoter source, and the green disappears immedialty, the coins have been coated with a colored wax to give the a "nice" greem color.
