IronChests Mod Recipe List
Here is a link for the recipes seeing as the god damn Not Enough Items mod will not show the recipes for the chests:
http://thetekkit.wikia.com/wiki/Category:Iron_ChestsThese chests pretty cool. Diamond chest holds the equivalent of 2 double-chests (108 item stacks). Crystal holds the same amount as diamond, but you can see the items floating inside the chest, which is kind cool.
