recrystallization...   ...as far as solvent systems go pick your winner. I'd chose an alcohol/xylene dual solvent system but that's just me.

Crystal growth is a basic science and can be accomplished thru a number of means most starting with pure product to begin with and a seed crystal. Slower crystal formation the better. Zero gravity has been shown to produce near perfect crystal structures so keep in mind that moving a growing crystals will impart G-Forces in any number of directions making less perfect crystals but I doubt its to much an issue in this case. I have grown crystals in kilns on ceramics and its a bitch at first. The trick to getting large crystals is to rapidly drop the temperature of the supersaturated solution to a relatively few degrees below crystalization point(hundreds of degrees in my case) and rise the temperate back up to slightly above the point where material crystalizes out. The rapid cooling promotes fewer seeds allowing for larger crystal growth. I was working with ZnO crystals in Alumina/SiO mixtures as the solution at temperatures in excess of 1100 degrees C so keep in mind that the values will vary but the basics stay the same.

Super saturate your solution.
Place seed, either manually or thru the process discussed.
Maintain temperature at point of crystalization for as long as possible.

You can grow monsters this way if you have all the correct data on the compound.

Discussion of kilos of material isn't exactly needed here so in situations like this please be a vauge as possible since it will just bring unwanted attention to us and yourself. I believe we have discussion here on the recrystalization of this substance in question.

i'm pretty sure that was the situation, it fell off a truck.
and i think my friend was just talking crazy anyway.

it won't crystallize if it's the racemate?   why not?

From my ignorance...and being a newbie  here.... but with all times great succes,i usually dissolve the final puffy mdma,totally dried and acetone cleaned on a minimun amount of lab grade boiling methanol,onlly ussing the minumun to total disolve the batch.Then let it cool slowly and let it evaporate at ambiente temperature.It takes like 2-3 days,with almost all the methanol way out on the first day and endding with a beaker plenty of  oilly crystals that takes two days more to completly get oil free-dry-crystallized.
    That gave me beatifull weird flat cubic crystalls 0,5 cm large ,and on good cases,letting the beaker alonge without curiosity shakings,get all the bottom of the beaker polimerized like candyrock.I think that it´s what you want,and would be the easiest way to get it for the lazy chemist...like me
    I make that with small amounts,like 15 gr product,...but supposed to work on so  bigger amounts.
    Try to understand us about enantyomer issolation...to me...at this moment...seems to be things of the future!

yeah, the idea was to form the huge 90 gram crystal clusters that were coming out of you know where for the last little bit.
fluffy puffy white mdma is fine, but consumer critters see powder and they think "cut"

Even though i'm pretty sure the crystalline stuff could very well be adulterated somehow...  It just goes for a better bit, from the same stuff.

Ideally, it would only be moved in as pure as possible either way, but it is clear that one should have appeal, and appearances make a big difference.

This thread is starting to smell like shit. Since when is The Vespiary about discussing drug cutting techniques ?

i agree completly....
never selled anything to nobody
and of course....cutting it´s not the way to go at all

I apologize group I didn't mean to get off the positive track.  Also I wasn't trying to sound like a profiteer. I feel its ones moral obligation to not put anything out there that can hurt someone. Pure anything makes folk go crazy faster. Prime example: in the 70's and 80's they were selling angle dust or PCP. A very potent substance people didn't know how much to take and would toss the stuff on a joint and some consequently would jump off buildings and get shot multiple times by the police. Whats 10mgs look like to someone that doesn't know? They started dissolving it in formalin to control how much the end user takes, which the responsibility lied at their end. Also Heroin back in the french connection days. If you were a Heroin connoisseur and bought some pure H for you and your buddies they all would most likely die regardless of there tolerance. It had to be cut, it wasn't a issue of quality it was an issue of safety.

If its a racemic mixture (which is more than likely for MDMA) you wont get shit regardless of the method mentioned above. You need to separate the enantiomers first.

well said.  forget trying to get shards of mdma unless you're able to separate the isomers, but of course if you're able to pull that off then you'd be one hell of a smart individual

appearance means little.  there any many different techniques and solvents you can use to crystallize mdma in, each giving different looking salts.  just focus on getting it as pure as possible by whatever means are available to you, don't put all your money on appearance.  if you have shards of mdma then its adulterated

Yes we are above that here and even if we are not, We do not want to know. Its that simple. If your moral compass is broken don' let us know because its not our concern and we do not want to know.
