    Meth recrystalized ?    

Swim is useing denatured alc. and acetone to recrystalize his some what smelly rocks he picked up.  Was wondering if he started with a small batch and slowly added more dilute meth to the cold mother liquor and already formed crystals.  Would the dilute meth being added help make the crystals even bigger?

    Go back, Jack, Do it again    

The best way to make bigger crystals is to dissolve the ones you have again in fresh alcohol and grow them again, very slowly, letting the temperature of the alcohol solution fall slowly.

Adding more meth dissolved in alcohol -- partiuclarly if its dilute will more likely dissolve the crystals forming at the time rather than make the crystals you have larger. If you add more saturated meth/alcohol solution to the mix? I can't answer that question. If you let the resultant mix sit undisturbed and allow it to cool slowly, you will get crystal formation, but as to whether it will make larger ones or just additional ones, I cannot answer from experience.

I do know from experience that if you want larger crystals, clean the crystals made in an intital crystallization and then go back, Jack, and do it again. The second time around usually produces much nicer and larger crystals. Let it solution cool slowly and leave it undisturbed for lnger times to obtain larger crystals.
mostly harmless

    Time    

How slow is slow? and if more alc. is added, in time will the meth find its home or will it continue to stay in the solution?  Thanks for the advice

    slow is usually very slow    

slowness is not a trait likely to bee on the tip of a meth-seeking-bee's mind.

yet, time after time, it does seem to bee a friend toward the successful dream.

geez i have read some where i think it was worlok that the crystal meth is like wine, they cure with age (sp?) and ofcause the slower the bigger the shard like lava from a volcano..

and the bigger the meth molecule the stronger the meth, hence bigger the crystal? how can an already formed quantity of a meth crystal get bigger by recrystalising it gain?

and how can it become  bigger? hence stronger?

say you have a 1grm crystal of meth, and recystalise it again, how can you get more meth, hence a bigger crystal?

btw and do you use the same mother liquid when recystalising twice?

    The amount of meth wouldn't increase..    

I think it is more like having 10 .10g crystals and redissolving them in order to get 2 .5g crystals so the amount of meth wouldn't increase but it may decrease slightly.

Also, the size of the crystal doesnt reflect the strength of the meth.  Meth is meth.

    i remember reading somewhere about forming...    

i remember reading somewhere about forming crystals that when the crystals are being formed it will only stop forming that crystal when there are impurities.
So if you recrystalize once and end up with 10 rocks, the oustide of them would  be the  most impure bit, but when you recrystalize again some more impurities are removed and thus lets 5 big rocks form instead of 10. So if you keep recrystalizing them you should end up with one big crystal. I think thats how it works.

    Seed Crystals    

Anybee have the discipline to always keep a few honkin big seed crytals around to inspire bigger crystal growth in your theoretical recrystallizations?

so you get less meth in the crystals the second time but they are bigger shard in size

Yep! It's like a biscuit broken in two might weigh 30gms. If you break it into eight pieces then it still weighs the same, it's still 30gms of biscuit that you're working with. I have never yielded enough product to recrystalise, but I imagine you would actually lose total weight as the crystals got bigger/more pure. This would be assuming that some of that weight of the original product is impurities, and that these impurities are being left out of the crystals in the crystalisation process.

    Dual Grade Recrystallization
(Rated as: good read)    

Please keep in mind that recrystallizing will remove alot of the impurities. But in the process of doing so, some product is inevitably lost. And generally speaking; the purer you want your product to be, the more product will be lost. This is because of the simple fact that a carefull recrystallization implies that the molecules are kept from crystallizing quickly. Thus alot of product is retained in the mother liquor once the crystallization is complete. Because of this many chemist (myself including), choose to make a "dual grade crystallization".

As this thread is about meth - i'll use that as an example. When recrystallizing an unspecified amount of meth, boiling IPA is added to the soon-to-be-recrystallized-meth, while stirring and heating, untill everything is dissolved. This is cooled really really slowly. Usually the beaker is left in the 90°C oil bath, such that it cool with this as a "jacket". Once roomtemperature, it's placed in the refridgiator, submerged in some water which has room temperature. This will make the temperature gradient lower - thus causing slower crystallization. After a few hours when everything has reached the refridgiator temperature, the beaker is placed in the freezer (dont use a water mantle here - it will freeze). After sitting there undisturbed for about a day or so, the stunning crystals are filtered. These are the "grade A" crystals, ready to use (assuming the initial product was pure enough of course)!

The mother liquors are topped off with 4X volume acetone and put in the freezer. The grainy precipitate, is filtered ans saved in the "grade B" bottle. When its time for a new crystallization the old "grade B" batches are simply thrown in with it. The process is repeated ad infinitum (or untill you are no longer sane ). This way you'll get all "grade A" meth in the end , while recycling the semi-perfect meth.

Happy weekend and crystallization!

Jika Anda menambahkan lebih jenuh shabu alkohol solusi untuk campuran? Aku tidak bisa menjawab pertanyaan itu. Jika Anda membiarkan resultant campuran duduk terganggu dan biarkan hingga dingin perlahan-lahan, Anda akan mendapatkan kristal, tapi sebagai Apakah itu akan membuat lebih besar atau hanya tambahan saja, saya tidak bisa menjawab dari pengalaman. Saya tahu dari pengalaman bahwa jika Anda ingin kristal yang lebih besar, Bersihkan kristal dibuat di kristalisasi intital dan kemudian kembali, Jack, dan melakukannya lagi. Kedua kalinya sekitar biasanya menghasilkan kristal jauh lebih bagus dan lebih besar.
