Butane is a simple asphyxiant, it isn't toxic in any way other than the fact that if you breath too much for too long without catching a few breaths of oxygen you will die.. Same as breathing carbon dioxide, same as breathing pure oxygen. There have been no studies confirming butane as a...

What was your point again..? Was it that butane is non toxic and the action by which it makes you suffocate is it displaces the normal oxygen concentration which then leads to asphyxiation. It's the lack of oxygen that kills you, and if you really can't grasp the simple fact that people only...

*According to Fadedawg, aspergillus cannot be filtered out in a .2um filter and can cause severe allergic reactions in some people so it is necessary to identify what kind of mold you have and be absolutely sure that it's not aspergillus.

Your not wrong, the point of filtering like this is because it's extremely fast and just as effective as using a coffee filter, as an added plus you can squeeze the shit out of the cotton ball to get every last drop of solvent and like I said the solvent will pick up some of your precipitate...

You obviously misread what I just posted, the poison is in the dosage and the lethal dosage is far beyond a can of butane... Your whole argument is based on the premise that everything should be organic and anything petroleum derived is toxic in any amount, I would have to respectfully disagree...

I agree that the essential oils you spray are not of any concern to anyone. But it sounds like your arguing on the basis of anecdotal evidence, read an MSDS for any of butane, the PEL indicates that butane is non toxic in moderate amounts... 800pm for 8 hours is an acceptable exposure limit by...

What I meant by saying filtration and winterization should be performed at the same time is it would be easiest to: 1. Make your bho extract, then dissolve in a suitable solvent and freeze it until the waxes have dropped out the solution. 2. Put it through a syringe just like the one in my...

You don't have to cut out the spots infected with mold unless you want to, but obviously you would want to cut the moldy shit from the and run it separately. Winterization should be performed at the same time as filtration so as to only waste one syringe filter. The taste of the oil isn't going...

A quick little google search brought up this http://www.amazon.com/gp/aw/d/B008EKXPLO?pc_redir=1410011600&robot_redir=1 It's hard to find .2 micron filters in packs smaller than 50 and the whatman's are expensive as fuck. Those 1.2um filters aren't used in such specialized applications as the...

Lol this is a very ignorant statement, alcohol will not dissolve the mold... In fact, alcohol is used as a medium to culture mold spores in biology labs. Mold spores are anywhere from 3 to 40 microns in size, you will have absolutely no problems filtering mold from an extract if you were to use...

Winterizing causes the non polar lipids to drop out of the solution to leave you with a more potent hash oil.

Dry ice hash will usually just make sticky black hash oil.

I suppose you could just make a still and then you won't have to worry about the cost of ethanol per pint because you'll have gallons :D

He had read something on reddit saying that decarboxylation is absolutely essential for high quality extract. For the future maps, you should not take information from Reddit because anyone who thinks they know what's what can post, I suppose the same is true for the forums but at least the...

Like twitch said, do not water cure it's a waste of time and it's your buds are going to lose a lot of smell. If your using buds your end product should be good as is. Did you decide to use butane or alcohol for the initial extraction?

Skunkpharm put it better than I ever could. Caution should be used as with any other solvent but the precautions are the same and one should always take into account the danger involved when extracting. Also maps when your using anything other than butane I would absolutely recommend a vacuum...

Didn't realize that it was his first time making hash oil lol, so yea maybe he should learn a little bit about the tek down before he attempts a hexane wash. I figured I would give him the information he was asking for anyways.

With all due respect the same compounds are being dissolved whether the material sits in alcohol for 2 hours or 2 days, those same compounds will stay in the alcohol while the cannabinoids migrate to the hexane, the only thing is I didn't get much yield because there were very little...

I've definitely polished a turd using hexane so I'm not sure why everyone thinks it can't be done. Although my starting material was buds not shake...

Absolutely, a standard distillation setup would include: 1. A round bottom boiling flask with at least two necks - which would be used to hold the solvent to be distilled and a thermometer to monitor the exact temperature of the solvent as it distills. One of the necks will be connected a...
