Clear BHO?

centrifuge ya good idea. some terpenes evaporate off at really low temperatures too.

WHen I heat it up, I have a small leather Leatherman Case which fits perfect over a fiver vial. Then as it is hot, i can shake it without frying my fingers.
If ya break it down with constant heat, I find you loose yield and it becomes harder.
But if you give it intervals of heat and shaking, it takes less amount of heat, and yield is better and flavour is maintained better. A rotissaire inside an oven, dialed at the perfect temperature would work perfect i bet.
I am continuing to do my double dip method while doing BHO and I am convinced you will yield more. I mentioned it on another thread, but its simple:
start filling tube, when you think its near bottom, flip upwards while continuing to give it the gas, either go 5-10 secs or wait until its dripping back out, then flip back down and let golden yellow pour out. This way, the buthane gets to run by the bud three times, instead of a simple downwards action.

i dont think you get a noticeable amount more oil with the tip method. i tried it. maybe document it with yield differences...

I will definately try it, once i get enuf of the same product. Just getting things fired up, so it will be a couple of months.Hashmasta-Kut said:
Plus I am getting a Raynox closeup macro lense, in a few days, so I will be diving right into the oil with that lense. hehehe Trichs should look amazing with this thing added onto my cam.

if you took a piece of bho the thickness of a trich would it not be similar in colour? I think it's just the thickness adding more pigment... as for purging, I think many people way overpurge their oil, losing much of the flavour, I used to do this to myself.. I scrape the oil before I purge, otherwise I think you 'burn' it somewhat, I pull it into a pile, and put my pie plate on top of a 4 slice toaster, each side pushed down on dark while stiring with a toothpick.. after it pops I take the plate off and let the heat in the plate do the rest of the work, once cool, it's perfect, and very flavourful, it comes out kind of buttery and nice and moist, the longer it sits the more it dries out, and the more flavour it loses, I'm still trying to find ways to better preserve it. Ever tried the bho straight on the plate before purge? I did the first time I made it cause I was so excited, it was pretty nasty, it's quite obvious when any butane remains.. and my quick purge definitly removes all of it.

Yer gonna love that lens. It's gonna be great for bud shots, all kinds of hash shots, and the like.
However, I didn't want you to be disappointed when you look at BHO. The butane totally dissolves the trichs, so there won't be any in there to look at. You know the coffee filter that is normally put on the bottom of the BHO tube? Well, it's so dense that it won't pass a trichome. All it passes is the butane with the trich material dissolved in it.
This picture shows some red BHO, backlit, through a microscope at 45X power. Note the small black particles which are contaminants that got through the filter. These particles range in size from 2-8 microns and will get through most filters. However, note that there are no trichs, or material of any kind. Just pure BHO goodness.
Shafto, just a suggestion, but if you have a heating pad, the type you use in bed, just turn it on to low, and set the pie plate on that. I think that the lower the heat is during purging, the more it will help to retain the flavors. It's my theory that the heating burns off the oils that provide the flavor. Therefore, I purge just at about 90 degrees for a little longer. I use the heating pad, and I really like the results.
I hope this helps in some way.
Purge safe....

a heating pad, that is a good idea.. with the toaster 1 plunge on dark will take the cold outa the plate from the butane and heat it just slightly too hot to leave your finger for more than 5 seconds.. then the glass actually holds the heat in it for a very long time, the heating pad would be a little less heat even, I agree with you, as long as you get the butane out as little heat as possible is best, all you do is boil out the terpenes which give it the o-so-good flavour.. all of my oil taste just like the weed it came from now, but more concentrated.. it never used to though, because I used to cook it to death..

Perfect Keefhead, I will have to try my clone heating pad to see if it can get enuf heat to purge/dissolve it. I agree totally, more heat results in loss of flavour.
I find heat and shaking disolves the bubbles faster and here lately i have been getting the texture, I like. Massive heat seems to burn off the fine oils, which when cooled, gets harder. Whereas, using less heat and vibration, those oils stay in there and it binds better.
I got my raynox lense, didnt have time to play with it yet, though. When I mentioned trichs, i was referring to buds.

Clone heating pad. Great idea. I may try that next time just to see if there is a difference. With the thermostat, you have better control over the temps. Hmmm, I wonder what the surface temperature of these is....
Congrats on the lens. I can't wait to see your bud shots.

I'll experiment with a heating pad, but I don't get it that hot with the toaster, and I think that there would be a point using a cooler temp that you would have to leave the oil on the heat longer and you would lose more than you would gain, it's a balance, and I will definitly try the heating pad to see how it works, I think I have it pretty damn good right now, but I thought that I had it pretty damn good before I figured out how to make it better in the past too.

one outside thought............................could clarity of oil be a dependant factor on trich. color ????? most oil of good quality seems to be amber could ya harvest a batch early at the clear stage and less oxidation and natrual tending toward amber could one achieve the sought after CLEAR ???? 
im just thinking and wondering if any have tryed this to dis-prove it or if its worth looking at.................?

I tried with some early picked "Ledo Uno" trim and buds, and came out with a very light, but not near clear, result. It was also my first run with the okief tube, and maybe it made some sort of difference? More experimenting.....
That doesn't prove or disprove it. Heh, just means I tried a few times (well, 4-5 runs). The bubble was also more light, but not cream.
Alright smily, now we know what a growers gotta do! LOL

cant get clear with young trikes in a traditional butane method, but yes it is a lighter colored oil from clear trikes(ie immature bud).
How long after purging will the oil take on a more solid state? I have yet to bring my oil to a manageable consistency.... hashmasta you have some very nice hard looking amber-glass looking oil... how did you achieve this? much props to everyone else as well.... oil lookin' nice
I have taken a mass spec of BHO. I got a bunch of hits with super high mw (like around 800). some of these are undoubtedly the chromophores responsible for the color.
the majority of the colored compounds in plants are from chlorophylls. if you look at a chlorophyll molecule(http://en.wikipedia.org/wiki/Chlorophyll), you will see this large ring shaped bit with a metal ion in the center (porphyrin). that is what absorbs the light.
these chlorophyll molecules are non-polar. they dont dissolve super well in butane (better in things like benzene/toluene), but they do dissolve. nature has evolved to the point where these compounds are ridiculously good at absorbing light, so you dont need very much to have a colored extract.
there may also be oxidation products of the various cannabinoids that are colored, but they wont be very strongly colored, and you would probably have to take a solution of such BHO and bubble oxygen through it for a while to get an appreciable concentration of such species.
butane does not react with anything in the mixture. at all. saturated hydrocarbons are unreactive in all but the most severe conditions. That is why we use them for oil (car oil), plastics, solvents, etc...

I've noticed this phenomena as well. I have been checking out trichomes from various strains and notice that there is a difference in colour between strains. As Chief mentions, the colour of the oil is almost clear in some strains. In others I notice a slightly amber tint in the trichome leading me to believe that most oil is naturally an amber colour.
