Right-click the bottom half of the fridge to open up the freezer GUI. Here, you can freeze various items to turn them into something else. The freezer contains 3 slots, one for fuel, one for the item to freeze, and an output slot for your frozen item. (this is a little outdated and no longer works)
Fuels for the Freezer are as follows:
- The Cooling Pack freezes 12.5 items per pack.
- Ice freezes 25 items per block.
- Rotten Flesh is frozen into Flesh. Flesh can then be cooked either in an Oven or furnace to turn it into Cooked Flesh.
- A water bucket is frozen into a block of ice (after freezing, the bucket remains in the input slot, but is now empty).
- A lava bucket is frozen into obsidian (after freezing, the bucket remains in the input slot, but is now empty).
- A slime ball will be frozen into a snowball.
- Don't throw away those poisonous potatoes! Freeze them to turn them back into regular potatoes!
