Once I put a jar of chicken broth in the freezer, and it cracked. Is there a special type of jar that won't crack - will a canning jar like a Mason crack? Please and thank you.
Nicotine, PG and VG won't freeze solid in a normal residential freezer so you don't have to worry about them cracking glass bottles.
They will however thicken at those temperatures and may need to be warmed a bit before you plan on using them in your mix.
