@fernand I used a variable wattage "kick 2" module so I could change the final output of any coil I put into it. I varied the temp from "doesn't burn at all" - "just burns the terpenes" - "silky perfect hit" - "burnt oil." It's kinda necessary for what i'm doing with it unless I could find a great atty with a ceramic deck. I scrape little logs of hash onto the top of the coil. Anything less than 28g is kinda flimsy and doesn't push back against my keychain dabber to "catch hold" of the hash.
I have a garage tech co2 extraction machine and studied boiling points of different components of hash oil. I don't have a degree and am not a scientist, but as I understand it, a very high percentage of the flavor you experience comes from another oil family in plant called terpenes, Different solvent extractions gather a different array of these, and different purging techniques used to get final product leave a yet more reduced set from what you begin with. Hash is like wine, it takes not only the farmers skill but the extraction artist as well.
All those lovely flavor molecules have a much more fragile than THC and break down rapidly with contact of light, heat, cold, humidity, aridity, and good old father time. ANY heat applied to the hash rapidly releases all this at once (less than 4 sec of heat) especially with straight BHO/shatter/crumble. Co2 extracted oil has a larger and more stable terpene profile so you get some flavors off a second hit if you can't just beast it down in the first shot (15 sec steady draw for my average dab, not that bad). RSO, propane, and hexane oil all have almost no terpenes. Those processes decarboxylate the oil to a greater degree though so you get greater potency as a trade off. At the setting I showed in an earlier pic I don't get any burnt flavor, feeling, or excess combustion posing as HUGE VAPOR CLOUDS.
My problem is I work in nice restaurants where all you do is break taste down to a science. It has made me very aware of the breakdown. The hash I get is always strain and grow dependent for flavor, but can taste like menthol blue raspberry on the first hit (hogsbreath/blue dream mix run for that one) and I just don't enjoy any other hit nearly as much. For some flavor is not as distinct and it matters less. I wish it were the case for me.
Someone please make an atty with a reloadable silicone storage slot, that push button loads a fresh dab on my coil please. It's all I want for christmas. I will settle for the IGO-w5 cap version.
