This temperature is hot enough to start forging most steels and other metals. Step 4: Maintain a steady flow of wood fuel. Once you have your fire at the correct temperature, it's time to start forging! You'll need to maintain a steady flow of wood fuel during the forging process, so it's important to keep replenishing your fire throughout.
