So i am a blacksmith who has been smithing for a short time i consider myself still green, i would like to ask peoples opinions on what i should be using a fuel and where i can find it cheaply or even better make it myself quickly and cheaply. I was using charcoal burquettes as fuel but it will not heat my steal fast enough, is this an issues with my forge design and airflow or is it my fuel like i think it is. Please any tips and tricks would be much appreciated.
