This mod adds many new materials created by mixing standard materials together via essences. Each of these materials, by 1.0 release version, will have a block, a full tool-set, and a full armor-set. This mod also adds a smelting recipe for leather, created with rotten flesh, and craftable chainmail.
Crafting recipies: Get NEI!

I am trying to update to 1.7, it took a long time for MCP to update, so it took a long time for Forge to update, and Forge updated recently, and they changed the install process for SRC, so bear with me please!
