Description

The crystal furnace is a third tier furnace included with the mod by default. This furnace smelts items at a rate of 40 ticks per item without modifying the config, making it 160 ticks faster than the stone furnace. It can be crafted with a diamond furnace, acting as direct upgrade for it.

This furnace is equivalent to the emerald furnace.
