Super C Forge Floor and Doors

In this video, I make the Super C Forge floor (hard refractory) and doors (using soft firebrick). When you cut and shape the soft firebrick, be sure you cut/file them to a size that will still slide in place after you have put the slurry on them. Cut the end doors about a quarter of an inch shorter than the closest opening (easier to slide). Allow space for two coats of slurry in case you need to do a repair. Notes: The soft firebrick does not HAVE to be coated with zirconium silicate slurry, but if it is, the forge will be more efficient and the bricks should last longer. The coating is extremely difficult to cut with a hand saw, so initial sizing with the saw and rasp is important. I recommend using 2300 degree rated brick. I seem to have more cracking problems when I use higer temp brick. Higher temperature rated brick will work, but it is more fragile when handled a lot. Coating 2300 degree brick with the zirconium silicate slurry will make 2300 degree rated brick handle any heat the forge will generate. If you have higher temperature brick, go ahead and use it, but you may want to put two coats of slurry on it. If you have equipment to cut hard firebrick safely, it could be used for the end doors. They are harder to handle, but much stronger. If you use hard brick, do not coat it with the zirconium silicate slurry. Always use soft firebrick for the horizontal door. It is your responsibility to keep yourself safe when using the materials referenced in this video.
