Is there documentation available on the full list of items blacklisted by GT recyclers? I discovered the hard way that stone dust is blacklisted (first, it wouldn't go in from the hopper until I put some in manually, then after it processed around 5 or 6 stacks of it, I had no more scrap than I started with). I'm not upset about it, given how easy it is to get stone dust, but I'm curious what else is blacklisted without being listed in IC2.ini.
Stone, Snow and anything that derives from them via processing (sand, stone bricks, glass...).
Tiny and small thingies are also blacklisted.
IC2 recycler blacklist still applies aswell.
Also, there should be a NEI thing that shows the recycler blacklist. I remember opening it with the L key (recipe lists or something like)
