Preparation - Result: crystal or powder?

[salvatoretoon]

Ok SWIM has read almost every thread regarding cooking ketamine, SWIM has been wondering before he accquires liquid ketamine how you get the different types of ketamine the crystal form (salt/sugar like) and the powder form (flour like) - SWIM would like to know what makes them turn out different such as the cooking methods used to produce them and the most effective method also bearing in mind the potency and amount of yield that is gained from that method. SWIM as read of the various methods of cooking the ketamine its justt he would like to clarify how to produce the flour like powder form rather than the crystal form. He said one thing mentioned put it into water and re-cooking it would work. Also he feels that its worth mentioning that for the flour like ketamine he does not mean crushed crystals as when you crush the crystals he says you can still see the "glisten" from the sparkles which you cannot see anything of the kind in the flour like ketamine. SWIM would really appreciate any replys that could help. SWIM would also like to apologise for the long post but he felt it was necessary so he could be specific with his question.

Before my tree-legged parrot turned to IM he on a number of occasions evaporated liquid ketamine from Ketalar bottles. He would empty the bottles on to a ovenproof dish and put this in the oven at 60 degrees celcius. Then went hunting for crackers while it evaporated. This would leave him with flour-like powder. It's as easy as that. Becareful not to use too much heat as it will make the ketamine turn brown aka signs of degradation. How long it should be left in the oven depends on the amount, but having a look at it once in a while is probably the best way to go about it. Turning it into crystals on the other hand would require several more steps and additional chemicals for recrystallizing. SWIM has never tried this so he wouldn't know the specific method, and if flour is what SWIY wants, the easy evaporation should be enough.

SWIM thanks you on your quick and informative reply but SWIM would like to ask if a pyrex dish is suitable for this he cannot imagine why not. also SWIM asks if other methods such as the air dry methods would produce the flour form then also the plate over simmering water? many thanks

A pyrex dish would be optimal yes. (SWIM uses mainly household equipment for other reasons than efficiency...) Air drying or using a water bath would produce similar results. Neither will recrystallize the ketamine, so SWIY will get 'flour' either way.

SWIM have to note that, some brands will get crystalized when the water evaporated slowly, it depends on how much impurities (preservatives and such) is in the solution. So if SWIY's bottle contains little amount of impurities it is possible to get crystal K, and amount of crystalizsation depends on a few factors including the amount of time it takes, more time = bigger harder crystals. And also remember that crystals can be converted to flour-like K by using correct equipment for crushing them. also larger surface = fragile crystals.

hope it helps

thankyou for the comment, SWIM would like to know the 'equipment' that can be used? at a guess its not just a simple thing to crush them? because when the crystals are crushed you still get a sparkly powder even when very fine.

first you should use a very big flat dish in order to distribute K on it so there is just a thin layer of K solution, heat it by placing plate over simmering water. This all work to make crystals as fragile as possible, you may even get flour-like K after you collect your K using a knife. But if you still wants finer K powder read on!

The equipment for crushing K crystals is nothing special, use whatever used for grinding something, you can use a coffee grinder, which doesn't work unless you have large amount of K crystals. Another way is to use a special bowl for crushing/grinding stuff, SWIM don't know its name (as his is not Native english speaker), i think it is used in chemistry and also used in SWIM's country for a long time, which is called "Haavan" (هاون) in Farsi. Anyway, here in Iran, it consists of a bowl and something which used for pressing on the material in the bowl, they both made from stone or metal so they don't break while crushing. There should be other ways too, for example placing the crystals inside a paper-made envelope, made from hard paper, and then closing it and placing it in a flat surface and then pressing or rolling something on it.
Another way is to add something to solution to minimize the crystalization, which may not be an option as SWIY wants to get pure K.
Another possible way is to convert K to freebase and then crystalize by gassing HCl and then filter, which produce finest K HCl possible. this way is hard (for a non-chemist), time-consuming and you will lose some K even if done perfectly.

anyway, why the hell SWIY wants flour-like K?? finely crushed crystals works damn good.

Swim came up on a third of a vial, poured it out on a dish, let it air dry in some low light dried in 5 hours. Swim found some pictures that look similar to what he had and the process he used.
