You need dry wood pieces.......like pine, apple, oak, hickory, etc. Some wood really stinks.....I don't like elm at all. What do they use for fireplace wood in your area? Hopefully more than Duralogs! You'd need some of that, but in smaller pieces first to get the fire started.
Many ways to start a fire, easiest I guess is to crumble up a few pages of newspaper then surround them with small/thin wood pieces often called kindling. Leave room for air to get underneath.......then light the paper. Once the wood has begun to burn you can start to slowly add larger and larger pieces of dry wood. Never use green or fresh wood, it won't burn, just smoke.
I don't know how much heat the copper will withstand, so don't plan on a bon fire! Just keep your wood pieces thin, less than an inch diameter, and add more as necessary. Thicker pieces of wood can be split into smaller thinner pieces, that is broken down the length, not sawn into "plates."
