    Graywolf reacted to Purple Power in RIP Speckles   
    RIP Speckles, 2/27/18 to 9/9/2020. She died as a result to the fire set a few blocks from my house on Weds. She was an endangered breed, Speckled Sussex. I raised Speckles since she was 2 days old. She, like all of my pets, are my babies. It doesn't matter if they are a dog, cat, or chicken, I love and spoil all of them more then I did for my human ones. Speckles laid every day and was one of my winter layers. She was one of my lap hens, that would enjoy pets while telling me what's going on in the flock. Some times Speckles would lay an egg on my lap. She'd follow me around the yard while talking up a storm demanding pets. When she'd molt, her feathers would have more white tips then before. Her sisters and the hen that helped to raise her (Feisty) miss her very much. Speckles has been gone for a few days now and they are still looking and calling for her.   I know there is a chance that Feisty will go broody once she relies that Speckles is gone as she has done this in the past. I'm researching endangered breeds and thinking of getting one each: Speckled Sussex. Delaware, and 55 Flowery hen. The question is if where I get my chicks is still standing and have them.                   +5

    Hey Greywolf, thank you so very much!  In particular I am interested in the use of “vestal virgins....” quoted here from your blog:
     
    “There were later versions using leather aprons and tales of vestal virgins running naked through the flowering cannabis plants, and having the resin scraped from their lithe young bodies...”
     
    My question is, does Amazon carry “vestal virgins” in quantity and is there a money back guarantee on their purchase?
     
    Seriously though, the two links you provided are fine responses and they are giving me all kinds of ideas.... I really think that a lot of people do not realize the fantastic thing that is hash, or kief and they are surely missing out.
     
    For me it is easy to see why you see so many references to “manna from heaven” and hyperbolically pleasurable illustrations of the hash smoker in the literature of yore.  They were not exaggerating.  Hash is THAT good!

    Will you include extraction discussions using food grade solvents (ethyl alcohol)? Particularly, processing at low temperatures (below 100°) to capture all the cannabinoid "a's" (THCA, CBGA, CBNA, etc.)
     
    I know ethyl alcohol is low yielder (maybe 40 grams per pound of flowers) and is not very efficient, but my focus is 100% medicinal and second guessing which solvents FDA will prescribe when medicinal cannabis products are regulated by the Feds. Past sessions of reading chicken bones, tea leaves, crystal ball says: "hydrocarbon solvents will not be permitted for medicinal products"; besides the purging process (heat) destroys the "a's" and terpenes.

    Graywolf got a reaction from GeneralSmokeUpington in Simple Diy Pot Still For Recycling Alcohol   
    I recommend that anyone wishing to continue to use their alcohol until it is used up, discuss the ATF statutes with their own attorney, as there is not common agreement on the interpretation.
     
    I don't see that this violates ATF in that we are not manufacturing, or recovering alcohol, we are continuing to cycle it through our closed loop system process untill it is all used up, or lost in the manufacturing process.
     
    We are most certainly not avoiding paying drinking liquor taxes on the ethanol we use, and in fact don't even drink it after paying the taxes, but instead use it in a manufacturing process.

    Graywolf got a reaction from GeneralSmokeUpington in Simple Diy Pot Still For Recycling Alcohol   
    I'm sure those of ya'll whom have purchased high purity Ethanol have noticed that it isn't cheap with all the taxes heaped upon it, so here is how I recover and reuse most of mine that I've already paid over $20 a liter for.

    What I use , is a simple pot still made out of an All Clad stainless asparagus steamer pot, a Quisinart electric fondue pot, and a stainless mixing bowl, in which I have inserted 12 1/2 feet of 3/16" ID copper tubing.

    The salad bowl condenser rests on a modified cat liter bucket, over an empty 1.75 liter Clear Springs bottle for final collection.

    The only modification to the Quisinart was to bend the ears of the top fork ring down, to permit the insertion of the asparagus pot, and placed canning jar lid rings in the bottom, to suspend the asparagus pot above the bottom, so as to eliminate hot spots.

    I like the Quisinart, because of its sensitive controls for alchemy, but for distillation application, its controls are wide open, until I throttle it back to 250F for finishing off the oil or alchemy.

    I paid $60 for the first one and found my second one at Goodwill for $15, so do shop about. We have a couple of Rivals in the group, that don't have quite as sensitive controls in finishing and alchemy temperature range, but are accurate enough to do the job and cost about half as much.

    If you don't do the final cook off in the still, a fry cooker will also work, but the controls are most likely not sensitive enough for finishing in the still, or any fine alchemy.

    I don't recommend sitting a pot of hot Canola oil on the an electric stove and using the surface element to heat the oil, because you can add too much heat and over pressure the still, if you are not paying close attention to details.

    Careful with an open burner or any open flames, because even hot oil is flammable, as are any alcohol fumes that might leak out somewhere, should you not get the lid on straight, or hose clamped, or etc, something go wrong.

    I like the portable pot, because some of the things that I use it for, are best done outdoors, even if I have to use a portable generator. It also can't put in enough heat at 1.5kw to blow the lid o-ring seal on the pot, or a hose off, which are the weakest links in the system.

    I modified the All Clad asparagus steamer pot by drilling a hole in each pot handle, through which I slip two 4" X 1/4=20 round head bolts, that pass though an 3/4" X 2" x 8" Oak board holding down the lid and be secured with washers and wing nuts.

    I modified the pot lid, by drilling a pilot hole using Canola oil as a cutting lubricant for the stainless, and using a step drill to open the hole to 5/8" to accept a 1/8" NPT brass bulkhead fitting. I roll a 5/8" X 1.125" over the fitting outer diameter, so that it seals with only hand tightening.

    I've attached a parts list below for the above and the rest of the parts, but draw your attention to the use of a neoprene or Viton fuel hose for the application. Many plastics and rubber hoses leach badly in the alcohols passing through.

    Operation of the still is simple. The alcohol is sealed up inside the pot, which is set into the pot of oil, which has its controls set wide open, or about 375F. I wrap a towel around the pot and 1.5 kw fondue cooker, to conserve heat and speed up the process.

    A 1/4" fuel hose conveys the alcohol vapors boiled off, to the condenser, which is sitting atop an inverted cat litter bucket, with reliefs cut out. The bowl is filled with ice water, and after the alcohol fumes pass through its coils and reach the 1.75 liter bottle below, it is ice cold. Recovery is greater than 99% during this step of recovery.

    I keep track of how much has been boiled off by how much accumulates in the bottle of approximately the same diameter as the asparagus, and mark on it where I wish to stop distilling.

    I usually stop before all the alcohol is gone, and pour it into a smaller container to boil the last bit off to atmosphere where I can watch.

    Here is the parts list, and some pictures:

    1 All Clad stainless asparagus steamer
    1 10" Stainless steel mixing bowl
    2 1/8" NPT brass bulkhead fitting
    1 Neoprene O rings for lid 5.375" X .125"

    ntroduction to a cold extraction method for hash oil that preserves carboxylic acid form of cannabinoids THC and CBD
    By Kate Welch, Pharm.D
    The cannabinoids THCA and CBDA, short for delta-9 tetrahydrocannabinolic acid and cannabidiolic acid, respectively, are precursors to their more well-known and well-studied metabolites, THC (aka delta-9 tetrahydrocannabinol), the primary psychotropic cannabinoid found in cannabis, and CBD (cannabidiol), its primary non-psychotropic cannabinoid.
    Found most abundantly in fresh cannabis plant material (Eichler et al. 2012; Turner et al. 1980), THCA and CBDA de-carboxylate the acidic part of the molecule into the active molecules THC and CBD. This occurs primarily by exposure to heat via smoking, cooking, or heated extraction of the dried or fresh plant, but also can form more slowly over time via extended exposure to light and atmosphere (Hazekamp 2008).
    Until recently, THCA and CBDA were not considered to be able to survive metabolism (i.e. inhalation by the lungs or digestion by the stomach and intestines and processing by the liver); nor were they considered to have any pharmacological activity in and of themselves (Jung et al 2007; Takeda et al 2008).
    However, recent in vitro and animal research using extracted THCA or CBDA reveals measurable actions on certain enzymes and receptor sites, suggesting some potential therapeutic effects for these cannabinoids and necessitating the elucidation and refinement of specific extraction techniques that preserve these particular acidic forms of these cannabinoids in order to provide material for further experimentation and research.
    CBDA was the earliest discovered cannabinoid acid, in 1955 (Brenneisen 2002). As for THCA, there are actually two forms: THCA-A was isolated in 1965; THCA-B, an analogue, was isolated in 1975. Some plants express more of one or the other for unknown reasons (ElSohly and Gul 2014), but THCA-A is usually the most prominent, and the most studied (Brenneisen 2002). For the purposes of this article, THCA= THCA-A as found in the fresh or dried cannabis plant.
    First, it is important to distinguish between the carboxylic acids that are precursors to THC and CBD in the fresh or dried plant material, and those that are the acid metabolites of smoked or ingested THC and CBD, formed in the liver or tissues and found in the bloodstream and filtered through the urine for excretion.
    The primary non-psychoactive metabolite of THC is also an acid, 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (Foltz 2007). This metabolite forms via the enzyme alcohol dehydrogenase from the primary liver-produced metabolite of THC, the equally psychoactive 11-hydroxy-THC.
    Removal of pure THC occurs rapidly from the bloodstream; 11-nor-9-carboxy-delta-9-THC accumulates and continues to form and be excreted into the urine as the THC in the bloodstream or from tissues that secrete stored THC into the bloodstream. As a result, urine drug assays intended for detection of human cannabis consumption primarily screen for the presence of this particular form of THCA (Chesher and Longo 2002).
    Animal research confirms that biological enzymes do not themselves convert THCA to THC: pure THCA given to rats led to acid metabolites of THCA only, not THC or acid metabolites of THC (Jung 2007).
    THCA and CBDA lack psychoactive effects (Kwong 2002) even when administered in pure form by IV to animals or humans (Grunfeld et al 1969). There is no evidence at this time that the acidic metabolites produced in vivo share the potential biological effects of its acidic precursors present in the fresh or dried plant.
    Quantitative detection of THCA in raw plant material heretofore has primarily been intended to help predict the THC potency of a specific weight or volume of dried plant when it is eventually smoked or heated; liquid chromatography (HPLC) is preferred since it is important that the method of detection must not heat the sample which will immediately convert THCA to THC (Ambach et al 2014). Furthermore, lab analysis of this decarboxylation reaction provides estimates that smoking cannabis yields approximately a 30% conversion of THCA to active THC; other methods such as cooking or heated solvent extractions will yield 70-90% conversion (Dussy et al 2005). However, it is important to note that to date there is poor correlation between the percentage of THCA to THC conversion already present in a cannabis product to be consumed and the resulting pharmacokinetics (measurements in the bloodstream) or pharmacodynamics (measurable psychoactive or psychomotor effects) in humans. For example, a small study compared the levels of THC and THC metabolites (both active and inactive) in men who consumed a fixed amount of either a) a heated cannabis sativa extract; an unheated cannabis sativa extract; or c) pure pharmaceutical THC (aka dronabinol or Marinol®).
    The unheated extract, surprisingly, turned out to provide both the highest CBD and THC blood levels on average, suggesting that whatever CBD and THC was initially ingested from the cold extract was readily absorbed and persisted in the bloodstream the longest. The heated extract, however, provided the highest total exposure to THC activity because of the sum of THC plus active metabolite 11-hydroxy-THC measured in the bloodstream. Both extracts measured blood levels of THC on average higher than in subjects given the pure pharmaceutical THC, even though both the unheated and heated cannabis extracts were CBDA dominant strain (CBDA/THCA ratio >1) (Eichler et al 2012).
    While the above study provided some interesting evidence about the fate of CBD and THC after oral consumption from either heated or unheated extracts, it did not examine the pharmacokinetics or pharmacodynamics of CBDA or THCA, though there were more of these acidic forms of the cannabinoids present and ingested in the unheated extract than the heated one (and none present in the dronabinol). Thus, important questions remain about both the unique biological effects of these acidic cannabinoids on the human body as well as their potential entourage effects either kinetically or dynamically with their better-studied de-carboxylated metabolites.
    Here is some of the most compelling evidence that shapes what we know about the carboxylic acid forms to date: both THCA and CBDA independently of any other phytocannabinoid, provide significant anti-nausea and anti-vomiting effects. In rats, THCA appears to be a considerable anti-nausea and anti-vomiting compound. In a study conducted in 2013, researchers determined not only that THCA was more potent compound in this regard than THC but also that THCA apparently mediated this response via 5HT1a (aka serotonin) receptors rather than the CB1 (cannabinoid) receptors whereby THC appears to exert its own anti-nausea effects as shown in other animal models (Rock 2013).
    Researchers repeated similar experiments with CBDA as well, demonstrating that CBDA reduced both toxin and motion-induced nausea and vomiting in rats, via an as-yet-to-be-determined enhancement of 5HT-1A serotonin receptor activation (Bolognini et al 2013). Unlike the THCA experiment-- which showed THCA and THC exerting anti-nausea effects via wholly different receptor mechanisms--CBDA appears in vivo and in vitro to work pharmacologically more similarly to CBD (e.g. both via serotonin-receptor activation), though CBDA was shown to be more potent than CBD in its serotonin-receptor-mediated effects.
    Additionally, CBDA and THCA have been shown in vitro to block, in varying degrees, both cyclooxygenase (COX) enzymes 1 and 2, which are each distinct mediators of inflammation and pain secondary to inflammation. Non-steroidal anti-inflammatory (NSAID) drugs such as acetylsalicylic acid (aspirin), ibuprofen, naproxen, indomethacin, and diclofenac all work via COX 1 and 2 inhibition, and, like CBDA and THCA, contain a carboxylic acid group in their structures that suggests this part of the molecule is integral to the way they work.
    In one assay, CBDA but not THCA significantly inhibited both COX 1 and 2-mediated oxidation activity, with the CBDA showing a strong preference for inhibiting COX 2 specifically (Takeda et al. 2008).
    A second study demonstrated that both THCA and CBDA inhibited COX 1 significantly but only THCA inhibited COX 2, and by only a little over 30% (Ruhaak, L. et al 2011).
    Both studies showed that the carboxylic acid forms CBDA and THCA had stronger overall COX-inhibiting activity than their de-carboxylated forms CBD and THC, however. More research is needed to clarify the role the acidic cannabinoids play in moderating inflammation and determine whether or not they may be safer alternatives for this than NSAIDs, which have well-known dose-dependent or long-term use detrimental effects on the gastrointestinal and cardiovascular systems due to their COX inhibition.
    Lastly, both CBDA and THCA show in vitro activity at some of the various cation channel receptors collectively known as transient receptor potentials that play important roles in pain and inflammation signal transduction such as TRPV1 and TRPV4(the “vanilloid” type); TRPA1(the “ankyrin” type) and TRPM8 (the “melastatin” type). They can block, activate, or de-sensitize these to activation by another activator (Cascio and Pertwee 2014). These are likely additional mechanisms by which the carboxylic acid forms of the cannabinoids work independently of their de-carboxylated forms to moderate pain and inflammation both centrally and peripherally.
    The carboxylic acid cannabinoids CBDA and THCA are likely to be important contributors to the relief of nausea, inflammation, and pain that humans have attributed to the cannabis plant for millennia. What makes them worth studying individually today are not only their individual roles within the entourage of effects that cannabis is so well known for, but also in their ability to relieve nausea or pain alone while bypassing the sometimes debilitating or unwanted psychoactive effects produced by cannabinoids like THC that activate the CB1 receptor.
    The recent popularity of websites and electronically-published books extolling the benefits of juicing of fresh cannabis leaf or whole plants to treat a variety of ailments are likely attributable to the role that CBDA and THCA play on various biological targets as enumerated above.
    CBDA and THCA can also be extracted and purified out of most any other cannabis extract (Wohlfarth et al 2011) but, short of the capabilities of sophisticated chemical separation of CBDA and THCA from all other cannabinoids in a lab, one will most easily obtain an extract with a much higher percentage of the carboxylic acid cannabinoids via cold-process extracts of the fresh plant. The resulting extract must continue to be stored in a cool, dark place (Taschwer 2015) in order to preserve its unique characteristics, and should be ingested rather than smoked if the goal of therapy includes reducing the psychoactive effects produced by THC.

    A single stage pump will pump below 100 microns and it is only necessary to pump down to about -29.5" Hg.  As you pump lower, you start to boil off the cannabinoids at room temperature   See attached graph.
     
    You can bleed air into the system using the back fill valve, which will keep the pressure from dropping below -29.5" Hg and ask as a gas ballast to help keep the pump crankcase dry.

    We pass our material through a 10 mesh strainer, so that it packs evenly and put a wadded coffee filter in the column first, so that the butane is dispersed at the injection end, rather than channeling.
     
    You can also empty and repack your column, for a second run. You can tell when it is time to stop, by examining the material under a microscope for capitate heads.
