So many things can affect xtal growth. From slow growing long xtals to quickly crashing fine powder it is mot something I worry about anymore.
Did you ever check your fridge temperature?

modern said:I did; the fridge is at 3C. I think it maybe that I put the covered beakers into another glass so the smell of the EtOAc didn't leak but it still did. Maybe if I kept it longer in the fridge it would have worked fine.
Thanks for the info on the crystal growth... I won't try too many but would like to see if a slightly drier solvent does better. But I'm in no rush atleast now I don't get goo and fridge doesn't smell of EtOAc.

Ah, OK - I seem to have remembered something completely incorrectly or have lost my basic reading comprehension skills, so that previous post of mine can be disregarded.Brennendes Wasser said:So within that test it did not give goo when *too dry* :/
Instead it simply made a white layer of dust on top of the glass, but still being full precipitation. It is simply hard to remove so anyways not desirable at all. But from that 1 test only it looked like
NO water = whitish plaque on surface (but still 100 % yield at least in my case, so only other crystals you may say)
correct amount of water = CIELO crystals
too much water = goo

Thanks for the clarification
So how about fully drying the extract, then using citric acid monohydrate?Loveall said:It has been reported that too little water does cause issues from a hard goo to no reaction.
It could be that depending on several variables the issues at low water are varied. The type of citric acid (anhydrous or not) may start to matter a lot at low water levels.
