Sometimes I smelt coal ore to get more coal, so I can smelt trees to make charcoal, to make torches for my new underwater building, which I use sand and gravel to make, and one day the coal ore runs out and I'm stuck mining it. sent from meh Technology
Sometimes, I waste a lot of money on almost useless things. This one time, I spent 22 gold blocks to make a lava furnace, only to realize soon after that I could have used hoppers and furnaces to make something far more efficient.
1. You can get the blocks back whenever you want. 2. It smelts 5x faster 3. It takes up less space 4. It's shiny ooo Edit: 5. It's exactly 1/38th lava.
