I think this thread have to be ended with this last post 
I was experimenting deeply on the hydrate method,and since of course the crystalls are big and pretty as hell,not be able to get a chunk of more 2-3 grams.And talking about MDMA salt,because with MDA and water i can´t get ant crystall formation ,the bigger crystalls with mda and water are like sugar and very opaque.In my experience,MDA needs an evaporation from al alcohol to make giant crystalls,the better with methanol,very little with ethanol and IPA.I can´t figure out how you Letters can get a solid chunk from MDA....but i believe you you get it of course.Posibly the key it´s the very slow cold down,but the temperature control it´s very time consuming.
On the other side, i get the solution/explanation but with the undesirable need to use a cutting aggent like Epson Salts.The key is disolve mdma salt+anhydrous magnesium sulphate on ratio like 80% mdma 20% anhydrous magnesium sulphate on equal/X2 amount boiling water.
800 mg MDMA+200 MgSO4 on 1-2 ml boiling water.The key is disolve first the MgSO4,thing that take time with stirring and mortering the sulphate,that seems don´t wanna disolve but finally does,and then add the mdma.
Let on same recipient undisturbed,on less 24 hours transparent-coloured single homogeneus chunk..
I dreamed time ago that with the Calcium sulfate,but discard it because not able to disolve it on water...but MgSo4 does and crystallize the whole container quickly as hell.No need to slow cold down.And one can make it directly on the microwave if needed on 5 minutes.
I discard the MSN,of course it´s usually used on meth cutting,and saw form extremely big crystalls on minutes after fusing it with heat,....but seems on crystall mdma analisys data never found it,and i prefer to try to explain the chunks with things that usual are contained on samples,and that it´s common with Calcium Sulphate and Epson Salts...and because the reason of this thread it was not about "cutting",it was about underground chemistry procedures.

...but a scene from Breaking Bad,when the guys obtained the blue marmelade(saturated solution salt on water??) and saw how they putted the pans into a machine that seemed and incubator,make me think about crystallizing temp have to be important on getting a well defined pretty mass...and it makes great diference of course!
matey I have enjoyed very much reading about your progress both your successes AND your failures/mistakes
(just joking matey in case you're not sure
here is THE Very reason continued comments from the 'xmist' throughout a process are really helpful and
