Go ahead then. You blow your house up. You can get them nice and cold in a cooler filled with ice too. No sparks from an igloo bro. Read up before you contradict.
What to seal BHO extractor besides coffee filter/cheesecloth?

Actually I read quite alot. I take safety very seriously read my posts I preach safety. Heres some reading showing safety of cans of butane in freezer.
https://books.google.com/books?id=OZGy6-XRhhoC&pg=PT184&lpg=PT184&dq=putting butane cans in freezer&source=bl&ots=GD1k9IeFQI&sig=1LjKw2YNl_UUJuTwlIXR8-XSV5g&hl=en&sa=X&ei=_VcJVbjeIoWkNoupgtgH&ved=0CDIQ6AEwBTgK
And more reading

dont worry I wont blow myself up.
thanks
I could however see the big tanks failing mechanically as was already said

So if youve read up on explosions coming from seals leaking in freezers....then youve seen the pictures of blown up freezers and burnt down houses....but your smarter than those guys and you wont die. Riiiiiight. Do me a favor jesus, dont go preaching your bullshit to kids around here. I kinda like some of the people round here and dont want them to become a statistic. Blow yourself up for you superstar, cause you read some books that told you it was ok and ignored the pictures of burnt down freezers that say otherwise. Superstar.

So every just about every guide on here is wrong? You are confusing open containers (thermos method) in freezer. Yes that can definitely cause an explosion. Never once claimed to be jesus or a superstar. But you are definately a condesending dick tho

I agree that the larger solvent tanks probably should be in a explosion proof freezer.
Just in case any seals start to fail or contract due to the cold. The cans of butane... not that I'm suggesting this.. but i do store them in the fridge. Butane should be completely liquid and at almost 0psi when 30F . These cans in my opinion are a lot safer at lower temps. Although it is theoretically possible that a seal could start to fail. But the seal would have most likely failed on the way to the consumer if it was going to. The chances of your fridge exploding from a leaking valve on a can.. in my opinion.. is like
getting struck by lightning. But anything is possible I guess.

Dude, super simple idea, but awesome! I can't believe I never thought of that! That's a good one right here.
Thank you

I'm about to do some research on this but I would also like to ask someone with hands on experience.
So when you freeze the butane, or at least bring down the temperature, it becomes a liquid. Now my question is will it still come out of the can once you press down on the exit point, due to the lack of pressure?
I know we're getting off topic but hey lets ramble

When my solvent tank is sub zero it will not release butane even when the valve is wide open. This is confusing to some people as they will automatically think the tank is empty. When in reality theres a huge amount of liquid butane that will only come out of turned upside-down or the tank is heated up so the butane can build pressure.
Hope this gives you some insight on that question.

Very interesting. Thank you for the response. Makes sense

The relationship between temperature and pressure! Propane, in a sealed container at 70F is about 127 psi, but at 110F its pressure is raised to about 200 psi. It goes supercritical at 207F and 44 bar. Which is really easy to achieve. I pull vacuum first, then flip the propane tank upside down to fill the hose w pressure, and crack the valve for the tank holding vacuum to keep propane in its liquid state better and get the best fills.

One can manipulate gas to act in all kinds of funny ways. Filling in a vessel w negative pressure ensures maximum fills, and may lower the bp if kept in negative pressure. I put a tank between 2 slabs of dry ice. The tank started at 2000 psi, but as the temperature dropped, so did the pressure in a sealed vessel. The gauge read zero, but was lying its add off. The second I opened the valve, it released pressure, ice plugs, and was tempermental and more likely to spit out chunks of ice along w plant matter. At those extreme low temperatures -109F, most solvents freeze or become like a slurpy. Those temps can cause nasty frostbite and the worst is a propane carbon dioxide mixture or ether and co2 splashing on your skin. Splashes sting and spills burn as the water expanding in the cell walls rupture from instantly freezing. One learns quite quickly what not to do from their mistakes. I would reccomend not pooling up butane to evaporate in the freezer, but over dry ice is a better idea, if longer evaporation times are desired for whatever kooky reason one may have.

FYI, the body produces acetone naturally. It comes in food grade, and is considered GRAS or Generally Regarded As Safe according to the msds and the groups deeming the toxicity of solvents used. Ethanol changes DNA, mutating it and embedding itself so it passes to our offspring. It's why alcoholism can be hereditary. It's LD50 is also eye opening. Isopropyl is garbage and residues are nasty. It's used as a denaturing product in mouthwash, so drunks don't try getting high ingesting it. But the human body does not produce etoh or isopropyl as it does acetone, naturally.

Holy shit I remember reading about this a long time ago! Hidden information like this is too cool. But definitely doesn't take away the respect one should have with handling any solvent - obviously. As far as the relationship between Ethanol and DNA is news to me but I can see how that works.
Once again thanks for the info..
Also check this out. Found it a while ago and thought it was really interesting. You guys have probably seen it
