There's definitely a big black hole where GT info is concerned. Of course this is true of most mods. Feel free to contribute to the wikiAccording to NEI it requires 40 EU/T, with a voltage of 40 EU and 1 amp. So does this mean I can't use a basic fluid extractor as they are LV and only 32 EU/T? God I hope not, having to build an advanced one just to melt glass is a bit much (pretty sure we had glass workers long before electricity was discovered). And no, when I tried using Ender IO conduits nothing changed. I was thinking maybe it wouldn't turn on if it didn't have a valid output to pump the fluid but nothing changed when attached the conduits.
I wish it was as easy as using a Thermoinic Fabricator. Don't get me wrong, I don't mind GT being the focal point of the pack and using it to to build things instead. It is just here is so little good information out there to help debug problems.
Another odd thing I noticed - I can't actually even find the recipe to create molten glass in NEI unless I tunnel down to it thru the tin electron tube recipe. If you type molten glass into NEI it doesn't actually come up as a fluid at all.
Re. the LV vs MV fluid extractor, yep, you have your answer. Sorry for the aggravation
Re. the molten glass recipes, I wonder if its because there's multiple molten glass-like fluids.
