Hey Forgers. I' am new here and seek advice about building a forge. I wanted to build a gas forge but find the ceramic board and a couple of other kinds of insulation expensive and hard to get in Ontario. I don't have a problem of the building part, with all the information out there. I just wonder if its much cheaper to run a coal forge, and is one better than the other. I still have to acquire a decent anvil first to be able to work the steel. I appreciate any help and look up to those that are experienced. Thanks.
