Got my 100mg nic today!!!

One of the main reasons for using glass containers for storing nice juice at <32 F or <0 C is that some plastics can become brittle at low temps. Leaching or breakdown of plastic can be an issue but I'm not sure what the risk is with, say, 100mg/ml. Leaching problems are also dependant on what type of plastic. Every several years it seems that one of the common food container plastics are shown to be a problem for storage of food products.

The main problem with using glass to store liquids at or below freezing is the expansion of liquid and then bursting the container. As mentioned we can't get anywhere near close to freezing temps of PG and VG.

Also, Alice, I believe it's only water does that expanding thing as it approaches its freezing temperature. I don't think anything does that.

You are certainly right on that. I just looked it up because I hadn't thought about it but couldn't think of anything else that expands when frozen.

From article Substances that expand when they freeze - by Anthony Aylward - Helium


Now that we understand water, what other substances expand when frozen? Because of the lattice requirement, they are few and less known than water. Examples include Silicon, which is used in various electronic an technological applications, Bismuth, which in alloys and compounds can be found in chemical and pharmaceutical applications, as well as Antimony and Gallium.

{edit} Many of the things typically found in most freezers contain significant amounts of water. I keep 10 X 2 Liter bottles of water frozen in my big freezer. I use these for keeping food chilled and/or frozen in fridges when we have power outages. Also, our 12 volt AC needs ice to cool the water that the refrigerant containing tube runs through. Interestingly, some 2 liter bottles, formerly cola bottles, have held up well after being partially thawed, several times, over a 10 year period. I put a few drops of 32% chlorine in them and, also, leave head-room for expansion.
