thanks again.
sometimes budtenders express a preference for lighter-colored wax. I kind of figured darker color means more chlorophyll, i.e. more leaf/stem residue, hence lower quality - but I don't know. THC % seems to be one predictor of higher-priced waxes (and newer producers typically don't seem to get the higher %'s), but the price differential for equivalent THC % wax between producers can be huge (e.g. $12 vs. $25 per gram for near-identical measurements).
so what are the best indicators of high-quality BHO wax other than THC %? lighter color? flavor?
Unlike ethanol, Butane doesn’t really extract chlorophyll, the color of BHO is generally related to the age/oxidation of the trichomes as well as any pigments in the glands (carotenoids, anthocyanins etc)
My opinion on retail canna products is you generally get what you pay for - not always, but most times the better stuff is more expensive.
THC % tells you the purity of the concentrate but not necessarily the quality - you can have really clean and “pure” BHO that isn’t that great - especially with newer CRC tek; though preferences will be subjective. CRC is a pharmaceutical chromatography style filtration which removes “impurities” and has gained a lot of traction over the last year into many standard operating procedures, though many are openly not fans of CRC oil. The best way to find quality is to get your feet wet and try a few brands and also do a bit of due diligence if you can on what local Dabbers are gravitating towards.
That said, as a solventless advocate I tend to prefer hash/rosin over BHO. My favorite type of BHO is “liquid live resin” which is for cartridge pens: very clean, incredibly tasty!
lower temp and shorter time? sounds like it would be less complete extraction - but with so much cannabis around i guess it doesn't matter anymore.
Lower temp and longer saturation time. Butane is non polar so the solubility of lipids can be manipulated without extracting any of the green stuff.
Wouldn't running vapor through water, as in a water pipe filter out waxes?
since they are lipids they don’t mix With water (Insoluble) - same reason why lecithin is used in edibles to emulsify oil/water.
From my research the boiling point of the wax lipids is quite a lot higher than our vaping temps (nonacosane = 700F for example)
I believe this is one reason why combustion produces much more tars, from the “destructive distillation” of the wax lipid content.
