The same with other books that talk about gold plating. The problem is that gold plating has been around for 170 years, and is very technically pliable, so that just about anything you can achieve with alkaline cyanide gold you can do with acid gold and vice versa. Although most acid gold is still cyanide based, there is less cyanide so it's probably somewhat safer to work with.
