Wool Gin

The Wool Gin is a tool added by Project Red which makes it possible to produce 4 strings from one block of wool in a workbench. This tool thus allows the reversal of the production of wool in Vanilla Minecraft.

If the mod MineChem is installed, then you can decompose the Wool Gin with the Chemical Decomposer into 16 Iron (Fe) and 0 - 4 Cellulose.
