If we use a lead-lined glass or porcelain vase, then we fill this container with an acidified cold water. On the left, in the simulator we're showing a strong positive conductor able to heat the piece that were wanting to heat. Holding iron to heat by using a pair of tongs with insulated handles into the water. Our work piece has flexible negative conductor allowing us to manipulate the piece around in the now boiling motion water.
A resistance forge and furnace like electrolysis apparently heats quickly a piece of iron - first to red and on to white heat so quickly that a portion of the iron that was not immersed in this liquid is just slightly warmed.
