Description

The obsidian furnace is the fourth tier furnace included with the mod by default. This furnace smelts items at a rate of 20 ticks per item without modifying the config, making it 180 ticks faster than the stone furnace. It can be crafted with either a emerald or crystal furnace, acting as direct upgrade for both.
