I've been hanging around here for a while, soaking up this vast amount of information and experience which I thank all of you for sharing. But now im at a sticking point in a project im doing for a history fair, of course it deals with the early history of knives, tools , iron and steel but by what i've learned, sommething called the Catalan Furnace was used to transform cast iron to wrought iron.problem is, I cant find a picture or diagram for my backboard. any sketches, drawings, or help at all would be greatly appreciated
thanks
