biopharmacopeia, your experiences with 'flash evaporators' as you have called them in e-mails to me, and your preferences for 'near combustion' temperatures do not translate to the Purple-Days Disffusers. We operate at a much lower temperature than you are expecting..
Hello Purple-Days:
The E-mail I sent you was sent to your business. This was a serious purchasing decision-related inquiry in which I explained my preference for vaporizers that run hot, and you advised me the PD was not suitable. For you to have disclosed my personal experience and preferences was a serious violation of the confidentiality one presumes are inherently accorded to such business communications! It is not good business practice or Internet etiquette to disclose any personal information from your business communcations to this group or otherwise post this on the Internet.
And then, the purpose you used this for was to try to attack me or impugn my credibility, not address the content of my message. You never responded to the content/point of my posting -- that it makes absolutely perfect sense, that if someone does have a problem with stuff getting inside a PD and scorching, charring, blackening, etc., they can simply stand their stem vertical, such as adapting it to slide into a pipe bowl (of course, one that was never used for combustion). Among many considerations, us purely recreational users should keep in mind that many medical MJ users (and also users injesting other drugs, illegal or legal) may simply not be able to exercise the breath control and coodination needed to prevent stuff from getting inside their PD; and for them and others, trying out a vertical-standing stem makes sense (IMO).
And what is wrong with my preference for vaporizers capable of putting out [as you quote from my confidential E-mail] ?near combustion? air temperatures? This seems to be rather common here in FC. Isn?t it considered poor FC etiquette to make such judgements about other people?s vaporization preferences?
Yes, I misused the word "burning," using it in a non-technical generic sense. But just going back less than one page in this thread before my message, Vtac stated, "Yeah if you over pack the bowl (incorrect usage really), protruding herb is going to be touching the crossbar of the heat exchanger which can scorch it."; Hennessy1414 stated, "I was merely pointing out the PD has the potential to scorch some of your nug....you have to try to do it?; and WavyGravy stated "I can get it nearly black (which of course isnt good but i can do it." After my posting, you stated, ?Yep, the cross-bar gets hot enough to char the material with direct contact, and material that falls into the heat exchanger will get blackened (charred).?
Many people would commonly use the term "burning" for scorching, charring and blackening. For example, leave something in the over at 350?F or hotter for too many hours or days and many people seeing the result would remark, "You burned the?(whatever it was).?
I started my message with a well-qualified conditional-type statement, actually a question, "For those with a PD having problems with stuff falling into the heater and burning, why not stuff your tip (or whatever the proper term is for the stuff-holding part) standing vertically in a conventional pipe?"; and then explained on this. And I ended with the full disclosure: "[Note, I am not an owner and have never actually seen a PD. But I have owned very similar Eterra models predating the PD]." Yes, I misused "burning" in a broad vernacular sense that includes organic material scorching and turning black, and used this in the same sentence as ?PD.? But I never criticized or discussed the PD or its performance. If only current PD owners are allowed to post to this thread, that should be made clear.
?Flash evaporation? ? That deserves a new, different thread of its own. Simplistically stated, I am referring to hitting just 1 small hit?s worth very quickly with very hot air (short of blacking or combustion, unless one tries). For example, put 1-hit?s worth of very finely powdered stuff in a stem and quickly, for a few seconds, draw through air that is probably hotter than the combustion temperature and rely on the very act of vaporization (technically, as I recall, the heat of ethalpy or heat of vaporization) to cool and keep the temperature of the stuff below combustion (while the volatile materials are still there, before pyrolysis and then combustion sets in). This hitting a small amount of powdered stuff for just a few seconds or less with maximally hot air provides near-instantaneous vaporization, thus the term ?flash evaporation? and also related technical terms, such as flash chromatography. This and the resulting concentrated hit (providing ALL of the good stuff in just a short burst) could loosely be compared to the very quick incineration and inhalation of a single-hit from a bong (and, in my experience, is very satisfying). Many vaporizers, such as the PD, are not designed to give users the option of doing this. Flash evaporation is, thus, far removed from more mainstream ?vaporization? often involving long, such as 10 second or even much longer, draws.
Probably like many others, I would welcome a second PD model with some type of heater (air temperature) control, allowing the user to select the desired vaporization temperature, including hotter temperatures.
As an entrepreneur and inventor, you obviously feel (over?)protective of your product. Even if someone did falsely desparage your product (and I don?t think I did anything near that), that is no excuse to dig into confidential, business E-mails to attack that person or his/her credibility in FC. And on this subject, I?ve been using PD-like (in the sense of similar inhalation-driven, convection, hot metal-based heaters) since about 1994. This includes obtaining direct from the inventor multiple Eterra models and prototypes that predate the PD and that you often cite as inspiring the PD; and within hours of getting my first vaporizer, using the stem adapted to a vertical position and never going back to the horizonal motif. Like I concluded in my first confidential E-mail to your business (you), ?I thought you might appreciate hearing from a long user/experimenter with Eterra/Purple-Days-like vaporizers.? It seems not.
As I noted in my last E-mail to you, I ?recognize that the PD is the current reference or gold standard among commercial convection vaporizers. With more moderate-temperature, longer-draw, multiple-hit-load-type usage obviously working so very well for so many devoted PD fans, you are obviously doing something right, and I wish to expand my horizons, broaden my vaporization options, etc. by purchasing and using one of your units.? The PD is still on the top of my list to purchase when I get around to expanding my vaporizer collection.
Again, I apologize sincerely for inaccurately, non-technically using the term ?burning? in any way associated with the PD. And I apologize to the group for my responding to a personally-directed dismissal/attack with such a long response (but as is often the case in these situations, one feels obligated to do this). I hope this is the end of this.
:I regularly get 5 his on average to each bowl and I have also found TINY bits of ash in two of the fifty or so bowls I've had.
