Heavy Sieve
The Heavy Sieve allows sifting of Compressed Blocks with a small loss. It requires a suitable mesh to function.
Crafting
Usage
Right-clicking the Heavy Sieve with a mesh will insert it. It can be retrieved by shift-right-clicking the block with an empty hand.
Once a mesh has been inserted, the sieve can be right clicked with siftable blocks to sift them.
Ex Nihilo
In Ex Nihilo Omnia, an Iron Mesh is required to sift blocks. Any lower level mesh will break instantly on use in a Heavy Sieve.
In Ex Nihilo Adscensio, any mesh will work, as meshes in Adscensio have no durability and only split the loot table.
