Alchemy question

Well, my question is about alchemy.
I saw in wowhead that @Northrend Alchemy Research@ was used to learn new recipes. I did it 2 times and it made nothing, really nothing. Is it bugged or what ?? I dont wanna spend all my mats...
I mainly wanna learn how to transmute Eternal water in Eternal fire, etc, etc...
Anyone can help ?

i am not aware of that issue.since roflin has an alchemyst he is the one that has the answer try to pm him ingame or here

i haven't tried it myself but i know for fact that the inscription counterpart is bugged alwell and i have heard rumors the alchemy one is bugged too. So dont do it again till marcello's says so xD

Ok then. Ty guys for answering me so fast
Have a good day
