Have you ever played Tekkit, FTB? I sure have and i love equivalent exchange. So much that i've ported EE3(Latest Version) to bukkit, You can now craft the minium stone and transmute using your crafting table. I also personally wanted a way to use EE3 without installing mods which this solves.
What you could use this for:
Not much is done at the minute due to EE3 not having alot!
To craft the minium stone:

This crafting recipe is like this to make it okay to get but not too easy as minium shards aren't in the plugin!
Where can i find all the recipes? A full list can be found here or hop onto play.therealmsx.net and type /warp eeb for all the recipes!
But here's a quick list of what you can put with the minium stone
Cobblestone x [4] <-> Flint
Dirt x [4] <-> Gravel
Sand x [4] <-> Sandstone
Sticks x [2] -> Plank
Plank x [4] -> Log
Iron Ingot x [8] <-> Gold Ingot
Gold Ingot x [4] <-> Diamond
Iron Block x [8] <-> Gold Block
Gold Block x [4] <-> Diamond Block
Of course this is few of many, make sure to checkout here for more.
To get it without crafting:
Do /give YOURNAME 378 1 2 then right click the magma cream to turn it into a minium stone!
To add it to a shop
Simply add the value 378:2 to the shop sign as the ID of the item, Note you cannot sell minium stones like this. You will also have to put a note saying right click with this to turn it into a real stone.
