Sorry, this is probably a dumb question, but I just decided to try Gregtech 6 and I can't even make a vanilla furnace work. I crafted it from stones and fire starter, but I have no idea how to use it. It does not work automatically, when I put items into it and right clicking on the furnace with fire starter or flint-n-tinder basically ignites ground around the furnace, not the furnace itself.
