Searched around for about 30 minutes and couldn't find the answer I was looking for. It's probably right in front of me, but I'm missing it if it is.
Swim did 6 pulls into separate jars and put it in his ice-cold freezer a litle more than a week ago. He's been out of town since, but when he checked the morning before leaving there had been a very nice collection of crystals. Is his batch still "good", being that the jars have been left untouched since leaving, or can one freeze precip for TOO long?
