I want to create a private mod (1.7.10), that add some recipes of the mods Equivalent Exchange 3 and EMC Condenser (http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2104626-latvianmodders-mods-emc-condenser-elemite-coinsmod).
I create successfully the recipes of mod Equivalent Excharge 3, because I don't use a vanilla item (tested).
For the mod EMC Condenser I have to use a vanilla items (obsidian), but if I use it minecraft crash.
My mod on github (for help with the code): https://github.com/SkiFire13/EMCRecipe
The Crash Report: http://pastebin.com/MhmfPkV7
The flm-client log: http://pastebin.com/8WuVYXWs
Other information:
I use MultiMC for test my mod.
I used these guides:
https://www.minecraft-italia.it/forum/t-guida-come-creare-una-mod (I'm italian)
http://minecraft.gamepedia.com/Mods/Creating_mods/Adding_a_recipe (I think this guide is for minecraft 1.6, because use Block.nameblock. On 1.7 I must use Blocks.nameblock)

Thanks for help
Ps. I'm italian, sorry for my bad english D:
