I am just quoting basic chemistry really. Butane only remains liquid at room temperature because it is under pressure. At standard atmosphere it is gas at room temperature. Ethanol commonly used in extractions for example must be held above its boiling point to remain a gas. This is true of all...

I do not extract at all. I only refine what I obtain. I would see steam distillation not so much for fractioning cannabinoids but rather for those who wish less exposure to pinene present in extraction. This indeed is very efficient at doing that. A health benefit to one person could mean...

I own a plain jane lab microscope from years back. It is a three lense and can zoom down to cell level. If you want to know when precisely extract is decarbed fully, or when exactly the solvent is purged, then here is what I do when in doubt. I place the extract in a petri dish and heat it...

I appreciate why you are cautious about leaving extract out but I have had doubts for some time regarding theories about extract degrading thusly. UV may or may not degrade any component of extract however the amount of extract that would be converted by leaving extract in the sun if indeed...

Without stirring and adding heat to the point that the maximum temerature azeotrope of alcohol and water boil at, and leaving it at that temperature until all solvent has been turned to gas and disapates into the air, then no, you cannot purge extract completely by just letting it sit in...

I have used much iso in processing. Iso is poisonous only when it hits levels well beyond what is in extract that you purge. Government says that 8 ounces will kill a man but likely one ounce would be nasty as hell. When we evap it is to remove just traces of that much. I have vaped extract with...

I got 25 of these tubes in from Amazon because I needed just one lolz and the damn things were bigger than they said! Uhg! The stainless steel wool I got in also from Amazon from a company here in Oregon. Food grade. I use stainless steel cookware so it is nearly a necessity for my food prep...

The video shows my extract in my glass vac chamber at high vacuum and set in the sun. iPad was set to time lapse. Under very high vacuum and full sunlight it took a pretty long time to decarb, even in the oxygen depleted vacuum atmosphere of the chamber. Extract and fresh soda pop have in...

Here are photos of a chromatography run I did to purify medicine. From start to finish, the starting sample, then the sample absorbed onto Celite. Next is the set up used and then the test tube fractions collected top to bottom and left to right in the order they eluted off the column. Then a...

Good choice to avoid the republican party. I put a LOT of distance between myself and republicans, and even more distance between myself and democrats. I only associate with independent people and THEN only if they refuse to talk politics... I hope for you a full and productive life while you...

I definately cook off the residuals before using it. Tossing SS onto a hot burner and making it glow does the trick. I order my SS from a company in Oregon through Amazon. It is very clean but it is metal. This means that it was created on metal forming machines. ALL machines that cut metal...

The rules regarding a phase change of any substance from solid, to liquid, to gas form are not subject to interpretation.You can research further the concept of the three forms that matter can achieve however trying to discover a substance like aluminum that does not follow the rules will be in...

In order to produce a gas from a substance, the substance must be heated to its boiling point. Chromium boils and turns into a gas at 4841 degrees F. Nickle boils and turns to gas at 5275 F. In your example citing the data you present of a Bic flame generating a spot temperature of 3500 F, it is...

The budget just passed by Congress nueters the Attorney General making it illegal to use budget money to go after medical marijuanna - from the newly enacted federal budget (I call this a win); "None of the funds made available in this Act to the Department of Justice may be used, with respect...

Please post a link regarding stainless steel toxicity. When I worked in a machine tool manufacturing facility as a research engineer and control systems programmer my design drawings and efforts required the use of the whole range of machinable metals including stainless steel of any grade...

I have seen no references prior to you post that suggests stainless steel when used in the manner prescribed would damage the lungs. This would suggest that stainless steel could somehow produce a vapor at temperatures orders of magnitude lower than the melting point of stainless steel. If you...

I placed food grade stainless steel wool into my briar wood pipe bowl and packed it down tight with my finger. I dab a bit of extract onto the SS wool and then use a Bic to fire it up like a bud. The SS immediately turns orange in the middle and wicks the heat out to the sides of the bowl. The...

I use a lot of extract and process it myslef into pure using chromatography and steam distillation among other techniques. Obviously very little extract is valuable and inevitably I end up with glassware that has good extract coating the insides after I pour the rest out. Some glass is very hard...

Here is the web course that put me onto the idea and FULL credit to Daniel Pedersen who lectures in this video. http://video.ku.dk/dry-column-vacuum-chromatography-dcvc

Here is the middle fraction from the above video. All solvents removed by heating very hot then hard vacuum and repeating four times until extract no longer bubbles while hot and under high vacuum. From the vaping I judge that the extract in the photo is as close to pure cannabinoid as posssible.
