This mod adds a fuel called Ethern Combustible, it lasts 1.5 times longer than a lava bucket in a furnace. Also, there is a new ORE, it generates underground around Y level 20 and below!
Find the ore, make the Pressurized Ethern Press, and put the ore in the press, and BOOM new fuel for your furnace so you don't have to hassle so much about fuel without it being TO easy!
