Better VG ARTICLE:

"Pure glycerol does not crystallize easily, but it can be chilled to form a solid that melts at about 64.4°F (18°C). It lowers the freezing point of water, however, by an amount that depends on the concentration. For example, a 66.7% solution freezes at -51°F (-46.1°C). For this reason, it can be used as non-toxic antifreeze and for storing sensitive liquids, such as enzymes, in laboratory freezers."

Yep I remember when I was in the Army you got a pack in your C rations with I think either 4 or 5 smokes in them. Never knew what brand you would get. If it wasn't yours you tried a trade with someone.

Ours was either Marlboro or Newport. Easy trade either you liked menthol or you didn't. None of that silly lights stuff either, genuine cowboy killers.

Sent with no malice and not a whole lot of forethought from my new Galaxy Tab 4. Thanks Santa!

I remember when I was a small child and they used to serve you a warm meal on a flight and it came with those little packs of cigarettes.

First time I ever got on an airplane was to fly to San Diego for Navy boot camp in 1975. No smokes with the meal then.

well for anyone was wondering about the kuro coiler clones from tobeco i ordered tuesday from eciggity, just got them in today and they are quality. they are made of aluminum i believe, and have a hefty weighted feel. havent tried the originals or the fasttech ones as I havent tried those, but if the tobeco ones are quality ones, making some coils as we speak

 

[Kenna]

Which brand?

Cheapie one from Walmart. Don't recall the brand. It wasn't an expensive one. I didn't want to waste money if it didn't work.

Like ethylene glycol and propylene glycol, glycerol is a non-ionic kosmotrope that forms strong hydrogen bonds with water molecules, competing with water-water hydrogen bonds. This disrupts the crystal lattice formation of ice unless the temperature is significantly lowered. The minimum freezing point temperature is at about −36 °F / −37.8 °C corresponding to 70% glycerol in water.

Glycerol was historically used as an anti-freeze for automotive applications before being replaced by ethylene glycol, which has a lower freezing point. While the minimum freezing point of a glycerol-water mixture is higher than an ethylene glycol-water mixture, glycerol is not toxic and is being re-examined for use in automotive applications.[17][18]

In the laboratory, glycerol is a common component of solvents for enzymatic reagents stored at temperatures below 0 °C due to the depression of the freezing temperature. It is also used as a cryoprotectant where the glycerol is dissolved in water to reduce damage by ice crystals to laboratory organisms that are stored in frozen solutions, such as bacteria, nematodes, and mammalian embryos. Glycerol - Wikipedia, the free encyclopedia

Guessing the "Pure Glycerin freezes at 62.6 degrees Fahrenheit." is actually the melting point but had a horrible night's sleep so don't trust me on that.

Yes, the same Wikipedia article shows 64 degrees F as the melting point, in the box at the right side of the page. But water has a melting point of 32 degrees F, at which temperature it changes from a solid to a liquid. I've never seen PG melt, and even if it did, I just don't grasp how the melting point and the freezing point could be two different things. Insert shoulder-shrugging, palms-upturned smiley here.

Now I'm even more cornfused. To what temperature does it have to be chilled to produce a solid that doesn't turn back into a liquid until it's brought up to 64 degrees Fahrenheit? Is there a chemist in the house?

ETA: I guess this means that the temperature it turns into a solid on the way down is different from the temperature it turns back into a liquid on the way up. That's mind-blowing.

No chemist here. However, using google, it seems that what we use is glycerin and water. Anhydrous glycerin is a solid up to 64 degrees. Somehow, when glycerin and water are combined, it lowers the freezing point of both. And, as we know, it is very difficult to keep water out of glycerin.

Which brand?

I got mine about 5 years ago, my boss told me about it. I don't recall the brand, but it had silver colored AA's in it & they had no label on them. I called my old boss & she said that they haven't bought them but once since, & it had what looked like D cell batteries in it. They used them in their Mag lite & haven't bought any since. My mother bought a carton of AA's "for hurricane season", so I haven't bought batteries recently, except C & D cells for a real storm emergency (as opposed to my mother's tiny storms).

Here's an analogy I read on reddit that doesn't really explain anything, but is pretty good anyway

Even though the material "knows" it wants to be in a different state, it is sometimes easier said than done to get there. An ELI5 analogy: imagine you have 30 screaming kindergarteners in a classroom, all running around doing various things, and it is time for recess. Even though the kindergarteners would rather be at recess than the classroom, they might stay in the classroom for a while until you can run around pulling each kid off of whatever they are doing and communicating to them that it's recess time. While it might seem like you would never be able to find a kindergartener in a classroom at recess time, you very well might if the teacher in the classroom is slow and inefficient about rounding up all the kids and getting them organized, or if a particular group of kids is hard to pull away from what they are doing. Similarly, it is sometimes not so easy to organize enough of the atoms of a material to collectively change phase and "get the ball rolling" so that the atoms in the material figure out that it's time for a phase change.

It works for me, PapaS. I think my Dad once told me that there was a very slight difference between the temperature at which water froze and the temperature at which ice melted, but the difference with VG is ginormous.

 

[3mg Meniere]

So if you take it down to -51 degrees, it will freeze, but it will not melt until you take it up to +64 deg?

Somethin' like that, except that (as you previously mentioned) it seems there might be another odd thing about VG where the addition of water is necessary to make the freezing temperature that low. I'm as puzzled about that as I was about the huge difference between the freezing temperature and the melting temperature. I mean, it's not like VG combines chemically with water to create a new compound.

Yeah we used to get warm C rations they would get a big pot of boiling water and everybody threw their main course can in then just grab one out and hope for beans and weenies.

Believe it or not I think the best things in Nam era C rats was the cranberry sauce.

Well I got my Lemo's and Vapor Shark today buut think I will wait till tomorrow to set it up. Got to make some juice tonight. I am almost out of my fave so got to get some made. Think I will make 200ml so I don't run short again.

But...but... didn't you have some of those factory tanks/nickel-coils ready to go when the Shark arrived?

Apparently ya'll didn't leave 'em in long enough to warm 'em up completely. Saw more dan a couple of unpunched cans 'empty' da pot when dey 'exploded'.

My C-RAT story. My top locker shelf was always nearly full of H&MFs. Dat hot plate was da bestest item I carried across da 'pond' from da land of da big BX and round eyes (aka US of A)!!!

To keep dis 'vaping' related, I once did get a green & red labelled four cig pack of Lucky Strikes (in '67). What's puzzling is that LS went to da red & white packaging in '42. C-rats came out in '58. Have yet to find out da two dates connection (yes, have spent many hours 'digging' online).

Unfortunately, I opened da pack and lit one... just imagine a det cord fuse... *poooooof*. Dat pack unopened today could pay for whatever PV I could ever want!

Ok, so now you're just stalling. We know you have more than just RY4 to vape!

I called the Post Office help number that shows on their text messages when you tracking packages on USPS.com. My KFL+v2 left Jacksonville, FL on the 13th & disappeared into limbo. It's never taken more than 7 days for a package from anywhere in FL to get to my PO. It usually leaves FL, & then the next notice I get is when they hit the North Houston Depot to be unloaded, sorted & reloaded to come south to Alvin, (where it may not get to my box for another day or so.). I never got a notice that it even made it to N. Houston. PO already had someone assigned to it because the seller had reported it also, the day before. Within 45 minutes I had a text that it ha reached N.Houston. So it's been sitting at that depot for days. That Depot is already under investigation for delays, & missing packages. It got to Alvin on the truck at 6:52am, & was in my box by 8:36am. That surprises me that I got it that early. Normally they don't get packages from that 7am truck into the boxes until around 3pm. It must have been flagged or something, because the mail in this PO hasn't worked this fast in 3-4 years. We used to have a great Post Office, we had the same people for so many years, & everyone knew them. They've all left, & this new bunch (contractors) aren't good for much. I really hope they get a fire lit under them 7 it starts at N. Houston & spreads like dry tinder.

Watching Grumpy Old Men. Love these movies! Lemon & Mathau can't be beat. There's a new Odd Couple sitcom starting soon. I'm afraid to watch it! That reminds me, I need to put that on my list of DVD's to buy!
