I have lye, but its full of aluminum shavings, now how would i go about removing these, without ruining the sodium hydroxide its self??

you could put the mix into a small solution,,then filter out the aluminium,,then use the solution in small amounts to raise ph

or once yourve filtered out the aluminium, then evaporate the water off, leaving the lye for future use

ok thx man, thas what i thought, but thought better to confer with the knowledgable ones first.....

thx again.

and how do i get I2 crystals from 2.5% I tincture?

this im really not sure of?

any thoughts?

OR, go out and buy some more(its only a couple of dollars for fuck sake) and stop hoarding your money,,,actually,,as a rule in chemistry,,,youd have to say that the lye has a major adulterant in it and is now unusuable

say what?

sorry mate--i do the ammonia/sodium metal shuffle and wouldnt know iodine if it bit me on the butt

ohhhh

im just trying to use what is available to me... any other alternative would be far far too costly for a newb, on such a small scale, but its np, i have a little more literature to look up...

Burner, as they say on other sites-UTFSE!

Failing that, there is one method on the rhodium.ws site.

UTFSE this i dont know

what does that mean?

Use The Fucking Search Engine,,UTFSE

haha nice nice,, i am,

i should also read the label on the tincture, if i knew what was in it, id prolly know what to do

whatever tinc. you purchase, stay away from

the iodine that has povidone!!

no, no providone in this stuff

, nor in my ephi either

Ok, burner...todays your lucky day. And don't forget to thank rain man. I copied and pasted that off one of his threads.

Here it is------------>

Iodine Extraction:

Use per liter of 7% tinc 25 ml HCl (37%) (not critical, use some, use enough, a little more will not hurt.) add 500 ml water, add with stirring, one liter 3% H2O2

Or since you are american, a pint of tinc, a pint of peroxide, a cup of water and a shot glass of acid. Stir well, let it sit. Let it sit. Give it four hours at least.

Decant the fluid into another jar and rinse out the crystals in the bottom of the first jar real well, 5-6 times with lots of swirling. I filter through a piece of bedsheet and get all the crystals in there and mash real well, dry good, transfer to fresh coffee filters, put in a jar that has epsoms salts (dried) in the bottom, put a folder paper towel in, the sit the crystals on top. Try to dry the crystals as best you can to start..but come back and change the coffee filters after about four hours, the next day, etc...after two changes, the I2 is generally dry. If you react them still wet, use 1.5 gm instead of 1.2 and decrease the water in the reaction by 20%.

Leave the solution in the second jar, add about another 125 ml of peroxide and let sit until the next day. You will get another batch of crystals, up to 25% as much as before, usally about 10%.

Works fine. On a good batch you can get up to 50 gm of I2 from a pint. Usually you will get 43-46 gms. A lot better than the one ounce I used to get with three bottles of peroxide.

i can only get 2.5% tinc.

is that still gonna work?

yeah it works with 2.5% as well, take and emty you bottle of iodine in a platic bottle big to accomadate your mixture, then fill the iodine bottle with peroxide, that will give you your 50/50 mix then adjust acid and water to the smaller batch, I usually go with my best guess, like a spoonfull or capfull of acid, just don't over do it, you will just yield less crystals with 2.5%

Although there are many ways to get the crystals out of the tincture, it is best to at least follow the reaction in regard to the order of chemical additions.

1. Add 2% tincture (it should be 2% iodine and 2.5% sodium iodide or some shit like that. If its not ok no problem. Still do it the same way) to large jar or plastic jug.

2. Acidify. You need to make the solution acidic first and let it rest and equalize a few minutes

3. Oxidize. Add the H2O2 last.

With 2% you don't need to add extra water like in the 7%. There is plenty already.

Please remember, you can find all of this and much more if you just take the time to use the search engine. If you are too impatient to search, I hereby summon the meth gods to fail your first 10 reactions.

Don't be cheap, don't skip steps, and don't seek out the quick and easy.
