I've been hearing about this book for years...but never got around to reading or buying it.
I noticed for sale on Bubbleman's site and it was delivered to me recently.
This book is definitely a must for any person interested in all things related to hashish,.

btw there are several photographs in this book by Bubbleman, including several of the Bubble box, closer ups of Sam Skunkman's dry sift and other macros..
i noticed that today too. the book is the best i have seen of its kind.
Yes this is a great book for any Hashish Connoiusser.

I've read about 25% of the book and Clarke mentions numerous times that less than 50% of the THC is removed from the plant material with dry sifting....
"neither method (hand rubbing or sieving) extracts no more than one half of the total THC contained in the floral clusters"
this has not been my experience at all when it come to grinding down bud for sieving with the intent to remove the max amount of resin glands. After I dry sift material there are less than 5% of the resin glands (visible through a 20X magnifying glass) left on the material and smoking this sieved plant material will not get me high at all, it wouldn't get an ant high, even one with a low tolerance... I've also in the past tried alcohol extractions on sieved material and the returns were tiny, the same with butane extractions..I've also ran fully sieved material through Bubble Bags and the resulting tiny amount of hash was not worth the effort....so based on my experience, I have to say that Clarke is incorrect on this point or I didn't read it correctly??.
Not bad, 25% done{Gotta be what 100 pages} and that's all you could find to complain about. Let us know how the rest goes. Peace GS
and that's all you could find to complain about.
I've scanned through the book and now I'm reading it word for word, on page 83 at the mo...
don't get me wrong, it's a book that every grower must read, and as a hasher, I relish every page, it's 90% dry sifting related, so I am enjoying it even more than most....it's just that I was expecting the writing to be less pedestrian, Clarke is a better researcher than writer.....the cartoonish sidebar sketches are a bit outdated looking in a hippy-ish 70's way and there's no new methods or techniques mentioned. The new color photos are good, but the old black and white pics lack clarity and sharpness and need Photoshopping.
For the next edition Clarke needs to get rid of or greatly improve the old black and whites, and print lots more full and half page color photos. The book could do with a professional edit as it's a bit repetitive at times and would improve with a new cover too.
You did read it correctly, but your method of determining the amount of resin (THC) left in the debris may leave something to desire. I know when me and Clarke did the experimental work we found up-to 50% of the THC still in the debris, but it all depends the variety and the methods used. With easy to sift varieties like Skunk #1 or Sleestak it is easy to get more then 50%, if you have a good technique, and the materials are dry and ready. With some varieties, or not dried and cured materials, the yield is less then 50% of the THC as measured on a GC before and after sifting. With water sifting 90% resin (THC) removal can be done.
I was shocked also, I also tried the debris and it was shit. But if you water sifted the debris or Butane the debris you did get more resin or oil, what can I say? BTW I do not recommend oil, it was an experiment.
Maybe you just dry sift forever until all resin has been removed? I don't need to, so I don't.

you're correct that is it's all about the technique used...when I dry sift with maximum yield in mind there is definitely less than 10% of the resin left on the plant material..I know this for a fact because I have run the sifted plant material through Bubble bags or alcohol extractions on several occasions only to yield less than 10%.
maybe he's talking about gentle sifting for a short duration?
Perhaps Clarke should edit it to "up to 50% of the THC is still in the debris after dry sifting" or to "from 10% ~ 50% of the THC is still in the debris after dry sifting depending on the technique used"
anyway, it's not a big issue, just a little misleading, thanks for your input!.....and it doesn't detract the book from being, by far, the best book about dry sifting and hash in general based on a 70's perspective. I know cos I have bought two copies from Bubbleman's retail site. Though you have to admit, a modern updated version would be wonderful.

Perhaps that dry sifting yields between 1% (in your case) and 90% of the resin
BTW I do not recommend oil, it was an experiment.
Yes, we're in agreement there...some call it honey oil, I call it resin dissolved in petrochemicals
Maybe you just dry sift forever until all resin has been removed?
Sometimes yes, sometimes I go for purity, sometime both, but most of the time I sift the material up to a point to just before the sifted resin will not form together with thumb in palm pressure..then when the sifted material is magnified there is less than one resin head visible per square cm.
I don't need to, so I don't.

Yeah, we know Sam, we've read about how good it is and seen the photos..it's outstanding, no doubt about it Your secret technique can produce 99.99% pure dry sift, the downside is that you leave 90% of the resin on the material...which in itself is not that outstanding...post photos of 99.99% dry sift yielding most of the resin on the material and we'll really be impressed.
or post your 99.99% technique and I bet that others could further develop it into a higher yielding technique while maintaining near the same purity, now that would be really, really impressive.
I know this for a fact because I have run the sifted plant material through Bubble bags or alcohol extractions on several occasions only to yield less than 10%.
im a little bit confused....your actually arguing aganist yourself...if your saying you removed the majority of the trichomes in your "maximizing yield" method...and THAN your ALSO getting 10% on your oil(and thats a very very unscienctific way of coming to your conclusion)than that means you DIDN'T remove as many trich's as you thought...if you removed all the trich's there's nothing for the solvent to bind to and your yield would be a lot smaller if non existant....
I never said I removed all the trics, ...I remove a vast majority of them, less than 10% as you quoted me, (who's confused here?) Sam said that 50% of the resin is left on the material after dry sifting, based on my experience I disagreed as I find there is 10% (or less) left on the material ...I came to this conclusion after seeing the tiny amounts yielded when dissolving the already sifted material in alcohol or running it through Bubblebags..actually 10% is a bit high, I don't weigh it, 10% is just a questimate ...anyway the point is that the yield I got from extraction was a long way from being 50% (which was main point of contention) . When I finish dry sifting material, I throw it in the compost (as you do after Bubblebagging plant material) as the effort involved to try and retrieve the other 5% or 10% is just not worth it.
But if the material is lightly sifted, then yes, there probably would be 50% of the resin left on the material (but that's not something I would do though, "waste not, want not" and all that)
I hope that clarifies it for you ;)
