Here is a little photo-log of my adventures in medieval-style forge enameling as inspired by Theophilus from his book, On Divers Arts.
Above is the muffle furnace that I dreamed up after reading the written description in On Divers Arts, on page #. I attended a forging day put on by the Foresters of Endewearde. With the help of the many clever minds of the Foresters, we schemed this little beauty into existence. The base is a re-purposed, re-shaped ‘step-up’ from an 1800’s horse driven wagon. Originally, the flat ‘step’ was turned 90 degrees. We were going to just heat and bend it around, but alas, it didn’t survive the stress and we had to weld it back together. The topper was dished from a circle piece of mild steel. I created the disher by slightly cupping the steel on an anvil, then heating it in the forge and then pressing the heated metal into the upturned end of a piece of fire wood. Once it was fully dished, I cold punched the holes from the inside, creating smaller holes on the outside to discourage stray bits of coal from entering the furnace. Finally, a small hook was welded onto the top to allow one to pick up the topper during firing to check on the readiness of the enamel piece.
