Fun fact, a blacksmith I met when I first started with metal working used marshmellows to add carbon to the steel he was working with.
On the one hand, that sounds awesome. On the other hand, what a waste of marshmallows. Reminds me though, of the idea where you try to forge with bronze instead of casting it. Any idea how difficult it is? :V
Not difficult. Casting can make getting the piece in the general shape you want it first though. Work a bar of bronze into a tool, or cast a "blank" out of bronze and then finish it in the forge to make a tool. The trouble comes because the bronze melts at around a thousand degrees cooler temp than iron does. Unfortunately for bronze, the point at which it starts to glow from the heat, (forging temp for iron) is just short of the temp required to melt it, so forging it has to be done as guess work. It all depends on the material makeup of the bronze though. The more tin there is in the bronze, the lower it's melting temp will be. Bronze actually has a lower melting point than just plain copper. A thing I know for sure though, I prefer aluminum bronze. It has around the same melting point as straight copper, it's typically stronger, and it's far more corrosion resistant than normal bronze or brass. It's also a gorgeous material when worked into jewellery.
