Looks like the smelter for TE no longer uses sand.... uses Invar Ignots? Not sure what they are but looks like I'm sticking to the pulv/furnace method.
Also, for any who is interested in joining the server Fuzzie showed off in one of his recent videos, PM me with your minecraft name (yes, I do banlist checks). I'll send you back a PM providing instructions along with the rules if approved. I'll send a PM also with the reason if declined. Right now, the server is restricted to frequent posters in this thread. Hope to see you soon.
