Block Compression

Simple Easy to Use Compressible Blocks Plugin:

Use /recipes to see a list of all available compressible blocks, each of which is crafted with 9 of the source block. Uncompressing simply by putting the compressed block in any crafting screen and it will provide 9 of the uncompressed blocks back to you. You can also smelt any smeltable compressed block to get 9 of the smelted block. The compressed blocks are unable to be used in crafting recipes other than to uncompress each one, and they can also not be built with to prevent any issues with mining them. Installation is as easy as adding this plugin to your servers plugin folder, there are no dependencies at this time.

You can also click on any of the blocks inside of the recipes menu to see the recipe to make the compressed block in a new menu. Simply click the yellow stained glass to return to the previous menu.
