Hello, I am relatively new to blacksmithing as I just made my first pair of tongs yesterday. I built my own forge and currently using a small exhaust fan jerry rigged together to provide air to the fire until I can source a more permanent air supply. I am using Anthracite coal in my forge as it is the only readily available coal in my area that I have found thus far, and I have heard that it is somewhat a dirty coal and can produce clinkers. When I was forging with it I had to frequently clean the fire out and I pulled out quite a few massive clinkers. Is this just because of the coal I am using or is anything I can change to help reduce the amount of clinkers are produced? Attached are some pictures of my forge and firepot design. any advice or tips is greatly appreciated!
