Processing for #2 begins: February 11. As of March 2 (about 6 weeks total), awaiting results. If it's 6-8 weeks from processing time, I still have weeks to go. My own test took about 3 weeks from activation to completion, but that was a couple of years ago, so maybe there is a bigger backlog right now. Be the first to rate this.
Undo. kframe19. Yes, those kinds of fireplaces generally burned coal-depending on where you are they may well have burned lignite, which is a sort of in between peat and bituminous coal. The solid panels are a nice touch to have, still. Many times they've simply disappeared.
In light of this it is understandable that the fuel used for day-to-day cooking fires would also be used for forge fires as men discovered the various methods of shaping and working with metals. When coal was discovered it was found to produce a hotter fire than charcoal. As coal begins to burn, all of the various impurities (tars, oils, sulfur, various trace elements and gases, etc) are burned off, and all that remains is pure carbon.
