EB and TP powders? What should they look like?

[Nucman]

F-in around, the initial re-crystalizations were done, then the solution was left to sit for 48hrs, 24 of it was in the fridge. I filtered out the rest of whatever was in there, and it's very powdery like, almost like TA. In fact, I've been messing with both(fina/synovex) lately, and at 1st I thought it was TA. It's white, flowery, not metalic like TA, and nothing like the hard crystals in the initial re-crystalization. Would this be semi pure EB?

You need to recrystallize from methanol which is what you did?

Tp/T will be needles and Eb will be prisms and both should form in their own little areas.

What you could be seeing is dissolved/broken filler which made it through.

You will know more if you test it in methanol and then even more if you put in oil ONLY. If it's not T of some form, it won't be soluble in warmed/heated oil and will xtallize out or not go into solution at all.
