Make a small, practical forge

Step 2 The build stage...

Place the slate on the floor. Now, make a pentagon using 5 bricks on their sides. Move two apart to make a small gap, so that you can light your forge etc. Add your second layer in much the same way, except (if you only have 10 bricks like me) only using four. If you have more, use 5, but stagger them from the ones below.
