I will trade 1 diamond for 5 stacks of cobble. Cobble is for a build. Not for resale. Need something? I may have it. PM me for a trade.
I am cooking it. I still have a lot of coal and lava to cook with for now. I haven't used the lava yet, but wiki says it will cook more cobble, and faster.
I recently found out the same thing about lava, it melts like 120 blocks, but you dont get the bucket back D:
Cooking with lava isn't cost-effective, because - as people said - you lose the bucket. In the next version, you'll get the bucket back. However, cooking with blaze rods is extremely effective.
I have blaze rods from before the reset. I had forgotten about them till now. That doesn't mean I won't need them though. I'm smelting 5000 stacks of cobble.
