See title. I plan to build a shop one day. I'll be living near a river, and that river has a particular variety of clay that (I've heard) is very good in terms of being able to handle heat, so my plan is to use it to build my own forge. I am unsure of what fuel it will use, although I'll live in an area where wood/charcoal would be easy to come by, and I could possibly obtain coal but it'd be much harder.
I don't know anything about anvils, hammers, or tongs, so what should I look for?
