i did a propylhexedrine extraction and i am goin to let it evaporate for atleast a day, but i wanna know if its ok to put the liquid containing iso in the microwave.

appreciate it

Have fun with the massive fireball jackass.

I hope you are joking... I have put my iso hash oil in the microwave in 20 second intervals MANY MANY times... and I never ever see a problem, nor have I experienced anything bad, but I certainly wouldn't put too much in the microwave just incase it does somehow ignite.

Solvents can and will ignite in the microwave. I've done it.

What the fuck happened, it just doesn't make sense to me (probably because I don't understand the mechanics of a microwave) All I know is that it has safely worked for me.

And when it comes to liquid iso, I can't see said fireball getting too out of hand, that is unless you are trying to evaporate more than 50ml or so of iso.

I usually just put it in for 10-20 seconds to get the bowl or whatever the alcohol it is in, warmed up real good.

I guess I will stop doing that, I value my hair, my family, and even the 3 yr. old girl that lives upstairs :(

(I swear every time I do something involving solvents, I think of that little girl, and it adds to my precautions, ie. doing it somewhere else/outside)

El oh el.

lol, ok, well I suppose I exaggerated a bit. The way you do it is right, short bursts. But if left on steady it very well could heat up to the solvents flash point, which means all those vapors as well as the liquid will ignite. It's the vapors that getcha though. Flammable vapors in the right combination can actually DDT, which stands for deflagration to detonation transition. In other words, it starts to burn, and since the ratio is JUST RIGHT the acceleration of the burn gets so fast that it exceeds roughly 340 m/s and it is then classified as a detonation, though the actual velocity of detonation can be much higher than just 340 m/s.

And when microwaving solvents the REAL risk is stray ignition sources, which is what happened to me. I won't say what I was doing, but I was nuking some MEK, and didn't even think about the pilot light on my stove being on. Well the fumes built up, leaked out, and found their way right to the pilot light, and I saw the flame travel from the oven to my microwave, and though there was only a whoomph, the fireball was fucking huge, and it blew the door open. The liquid inside stayed lit.

It was really no big deal, as I was kind of expecting SOMETHING to happen (again with flash point) so I was prepared for it, and it didn't damage anything, and I blew out the pilot light and went right back to work.


But for evapping ISO you need to just put it on top of a running TV or computer monitor or some other electronic device, and the radiant heat from that device, with a fan, will quickly evaporate it.

I wasn't evaporating, but testing out something I had read about gakk busting.

Oh buddy, I know the fumes are where the problems arise from!

The other day in my town a small mechanics garage blew up because of some fucks doing some undisclosed drug related business, though I think it was ISO oil or BHO because they were charged with possession of marijuana and production of "illegal drugs"

Also, I started a field party a few years ago, and while I was getting the fire started and shit, a few dozen people arrived, one of which was a dumb little girl who POURED a couple gallon tank of gas onto the fire, we all watched the flame climb the stream of gas and get closer to the nozzle, and the girl started screaming and dropped it on the ground, then I saw all these people do the over dramatic jump and cover as if a bomb was about to go off (I was one of these people by the way!)

I looked up from my daring half-assed escape and watched the only smart person there walk over to the flaming can, blow out the flame and carefully set it away from the fire.

Apparently a gas can has to be near empty to make an actual explosion... the guy was so calm about it hahaha... great night.

You've never seen someone put out a lit match in a cup of gas? It's the vapors, not the actual liquid that burns.


Think of it chemically. In order for something to burn, it must have oxygen present right? Well, there is no O2 in gas, so it won't ignite. BUT if you were to hold it above the gas, while the vapors come off, mixing in with air, it will light, and then the reason it STAYS lit is because it's just the vapors coming off the gas as if it were not lit, but the heat makes it evap faster, burning faster and more strongly etc.

Each gasoline molecule must be in contact with an oxygen atom in order to burn. Just like flash powder, too little oxidizer, and it doesn't really burn, OR if it is not mixed well enough. It's all about surface area and intimate contact.


Fire needs oxygen. There is no oxygen at the bottom of a cup of gas, hence, no fire.

Now if you were to take gasoline and mix it in the proper ratios with air it would explode. Hmmm, maybe there is a way we could harness that power for locomotion.

Hey Nitrous, haha

Cant you find some other means to heat the solution? Such as under a flame.

If only... We wouldn't have to use all these other, more efficient gasses... bummer.

But as for not knowing this shit... man, I was a sheltered kid up until 12 or so, and tried as little in school as possible the whole time... infact a teacher most likely described these properties directly to me, but I was too stoned or bored to care... somehow NOW I care to learn!?

So what you are saying... In a kind of round about way, is that your head is hollow and you have shit for brains?

i use to use the microwave to heat methyl alcohol. but only for 1 minute tops. just to get it really hot.

WTF!? No, use an electric burner. You can get for like $7-$8 at Wally world, if you really need one.

ive evaped iso over flame before....

i found that as long as i took it off the heat, moved several feet away and blew out the alcohol vapor it wouldn't flash on me... except that one time when the right concentrations blew over the flame and then i had a small fireball...

a better solution is to boil some water... let it cool down a few degrees.... place your container into the almost boiling water... when it cools, remove the solvent container and reheat... no ignition source = no explosions....

or keep the water at a steady temperature with a hot plate...

fire and solvents dont typically mix...
microwaves just seem like a bad idea... it seems like your going to be evaporating a solvent in a closed non ventilated space... and the vapors getting hotter and hotter until ignition.. SN pointed out large fireballs occuring...

(I swear every time I do something involving solvents, I think of that little girl, and it adds to my precautions, ie. doing it somewhere else/outside)

OMG... that's kind of... romantic...

...anyways... if I were evaporating organic solvents... somehow, "an enclosed box to contain the vapors, in which the entirety of the walls of said box happens to consist of generators of electrical sparks," would somehow not be high on my list of "ideal evaporating devices."

In fact? I'd rather set it on fire in the middle of the floor, than build up vapor pressure in a spark generator. Less risk of fires doing strange and uncomfortable things that way...

...though floating a warmed plate on hot water is usually better than, well, setting it on fire. At least as far as saftey.

This is what I always do when evaporating flammable solutions.
