The Neutronium Compressor is a tile entity added by Avaritia. It is used to compress blocks into singularities. Right-clicking it will open its GUI, with one slot for input. Putting one or more of the input item into the Neutronium Compressor will start its processes. The GUI will state how many more of the input item is needed; most recipes require 12,000-15,000 items for completion, and cannot be put in with one stack.
