Blaze Furnaces, another tier of furnace. Made of a metamorphic furnace surrounded by blaze emeralds. Has internal store of fuel usage (put in a coal, store is now "8". Put in a lava, store += 100, etc). Smelts at 6x normal speed, and does all the special recipes carbon can do. Has internal inventories, probably 2x3 to 3x3?
Store prevents wasting of fuel, see.
I think that the recipe should instead be 8 blaze emeralds around a carbfurnace. that way it's much more similar to the carbfurnace recipe, and makes more sense IMO.
sand, logs, netherrack, logs, clay take as long as ores do in a carbfurnace. ores take 30% longer than that.

....you changed that one digit, but not the stuff that's wrong? :P
No green flames yet, custom particle rendering is gross and disgusting. Probably fixed in 1.6; if not I'll do the gross and disgusting part then.
