    Amalgama: Using Mercury to capture fine gold, retort

    There are two types of Mercury retorts, which are vented and non-vented. The non-vented type is simply a boiling vessel and a cooling tube from which the Mercury drips into a catch vessel. With this type of retort NEVER put the exit end under water in a catch vessel. If you do, a very slight drop in the temperature of the boiling Mercury will create a vacuum sufficient to suck
