Thats right, get your propane.
INSTALL
1: Copy this picture
2: Place the PROPANE block over your old coal ore block, and the propane tank over your coal object.
You have to edit the pictures in a painterly pack or some reskin. In the painterly pack, the coal ore is found in terrian, the
coal object found in GUI/items. Open the pictures open, place the propane skins over them, and install them.
RUN YOUR FURNACES CLEANLY AND EFFIECNTLY.
PS: The propane blocks are blocks that Hank Hill stored around the world in case of an emergency, and make coal as easy to find as a small child in a small child factory.
