You don't think that the cardboard will insulate against the cold? Seems as if it might and we want it as cold as we can get it.
Hey randy do you plan on getting in the flavors apprentice ry4 Asian flavor in any time soon?
Sorry for the late Thank You!! My online time is spread way to thin across many sites these days.
Thanks or all the flavor tips, with so many to choose from, It sure makes more sense now.![]()
A quick question on freezing, A friend I referred to RTS is using a technique that i thought was interesting.
He splits up his liter into smaller bottles and freezes one at a time with the cap off to assure it don't break and least of concerns to minimize the air at top, then caps it.
I wondered if the nic would absorb anything else in the freezer. I'd be concerned (as minimal it may be) if last weeks leftovers seeping into my new nic and then become my flavor of the month...lol
His family has been freezing for years and thinks that the lids/caps may be the cause of some breakage as well?
Lids to tight, threads not matching up quite right...![]()
Just tossing ideas around before I start freezing my new stock.
thanks
It's my understanding that unlike water, PG and VG don't expand when put in freezing conditions, but may actually shrink a little. Here's an informative post by a chemist who is a regular ECF contributor http://www.e-cigarette-forum.com/fo...freezing-100mg-nicotine-base.html#post8715793
Yep, if there is not going to be much exposure to light, there really is no need for colored glass.
I know that originally Kurt posted the less air space, the better. Recently I saw him say somewhere in the DIY forum that a little air space is actually better. I am sure that either way works though.
ETA- I have also seen people use clear glass jars and put a sock over them to block light lol
Understood.
Still little headroom, just that Kurt had filled to the brim, got bit by the tiny bit of vg expansion due to temp increase. Pure glycerin expands about 1% per 20C temp increase, in the temp ranges we use. The nicotine and little bit of water will change this, but it is a ballpark.

Then im not loseing it as i age as i recently acquired 1 liter of 60mg from Randy and filled 2 - 500ml bottles first one filled all the way second one ran short of the top and did this in kitchen then put right in garage freezer.Just throwing my 2 cents in. Keep in mind we have a lot of bottles on ice at any given time at minus 10 degrees F. Consistent with what everyone has said, both PG and VG diluted nicotine shrink when brought to this temperature. You NEVER want to fill a bottle to the point where the neck (with threads) has fluid in it. Filling it ever so slightly above where the cylindrical part of bottle starts to slope up is best.
