I am currently constructing a new forge design that me and my dad came up with to replace my old fire-pan forge. This forge will be constructed from individual firebricks, not mortared together in any way. Air will be introduced through a pipe that runs through the concrete base to a hairdryer. Since the bricks are not mortared together, I can construct many varying designs, both horizontally and vertically oriented, which can be changed as the current project requires. I already have the concrete base constructed, with the concrete drying as I type. I'll post pictures as soon as the concrete is dry and I can demonstrate the principle. The main thing that bothers me is that I don't know what to call it. Please post with questions or tentative classifications. It does burn charcoal, but beyond that, I don't know how to classify it.
Thanks.
