I had an idea for a vaporizor I wanted to build, that in my opinion would be the perfect way to do it, without creating a vacuum; as well as being easily constructed and not purchased.

So far, I have yet to try it, but after roaming the forums for a while, could not find much related information, except a huge thread on whether is water soluable or not.

The basic concept is similar to a double boiler used in to gently heat things in cooking. You would grind up your herb and place it within a class vessel, with some sort of hose attatched. Then you would submerse the vessel in boiling water. Now, since the heating element is no longer in direct contact with the plant matter like most cheaper vaporizors are; you no longer risk burning anythings. The boiling water would then heat the THC to its vaporization point, resulting in perfectly vaped herb.

Again, I know I am not pioneering anything here, and that there are devices available that vaporize perfectly everytime; but I am unwilling to spend that kind of money on something that can be done in a cheaper manner.

Any thoughts?

how would the boiling water heat the thc to its vaporization point?

Well, boiling water can easily reach 200-300 degrees [F], which is also the average temperature range for the THC crystals to begin to boil, and vaporize. Also considering that the herb will be contained, the increased pressures inside the glass vessel will also help elevate the temperatures for vaporization.

doesn't water boil @ 100 celsius?

yeah something doesnt make sense

just save up a couple hundred and get a nice vaporiser when your good and ready.

vaporisers are meant to be done right or not at all.

hey now guys dont shoot him down

i think it sounds like a fine vape, just fiiinnneeee

Steam can hit 2-300F, water cannot. You're gonna need a fairly complicated system to pass superheated steam over weed without burning yourself every time you load a bowl. Also most good vaporisers have digital thermostats, which do not burn weed.

@Flamingnun: I boiled water just now and measured it with a digital thermometer and it registered 243[F]. Of note, this was when I noticed vapor being emitted, but not yet a rolling boil.

@Mikey: The whole point here is to not spend several hundred dollars on something that can easily be done for cheaper. Whatever happened to the pioneering process of creating our own pieces; as I am sure everyone here has done at one point. When did we become slaves to instant gratification and the dollar?

I am glad to see someone has more to say than 'It cant be done.'

water boils @ 100C, THC at about 200C,

You've confused C for F i think

Edit* 100 degrees Celsius equals 212 Degrees Fahrenheit

http://en.wikipedia.org/wiki/Vaporizer#Vapor_quality <- talks about temps, THC b.p = 157

http://www.erowid.org/plants/cannabi...ta_sheet.shtml <- gives b.p as 200C


Either one is too high for normal water boiling conditions, you look at the refs and decide which one is more accurate, or get some and test it yourself (/test your idea)

Mafoo

easy way to overcome the boiling point of water being too low would be to increase the pressure of the boiler. that also, unfortunately, makes the design 100x more complicated.

its a good idea. what about using hot air instead of water?

^exactly what we already do
*edit in some vapes - others use direct contact with a metal bowl to heat the weed

Marijuana Vaporization Temperatures

This link shows a chart that defines pretty specifically what happens to THC as it is heated to its complete vaporization point. You will notice that at 200-300[F] terpenoids begin to vaporize. Since these are the chemicals that happen to be fat soluable, the high would be akin to cooking with THC.

The process was never intended to be perfect vaporization.

C_ka

201-300 warming Liquid Resin continues to boil and begins to darken. Most of the terponoids have boiled off, flavor and aroma are reduced. Boiling point of least volatile terpenoids. Boiling point of THC.

That's in Celsius, not Fahrenheit

cooking with thc the effects vary mostly due to the different route of ingestion,

if this boiling water vape technique was to work (without raising the temp of the water with pressure) then we would lose THC when we boiled water/butter/weed to make the budder for eating.

I also think you appear confused as to the main psychoactive component of the weed - THC, terpenoids afawk have little to no biological effect
