color?

[Keith Jackson]

I have to know what is up with the color of liquids. I have been vaping cowboy for a long while now. I've gotten it from various suppliers and sometimes it comes crystal clear and sometimes it comes a yellowish green.

Has anyone else had this happen?

Nic turns brownish when exposed to air and there's always a small airpocket in each bottle. So the interaction of liquid with air continues. Fresh off the line, the liquid is probably crystal clear, but will darken when sitting in your or on the store's shelf for awhile. See the various threads in this ere forum about steeping and aging of liquids.
Should be no bother as you're not mentioning any discernible variances in taste...

Actually the main reason I am asking is the clear is fine. But the darker gives me heartburn like crazy. That was why I was asking. I was thinking it might have had something to do with the pg/vg ratio. I vape 0mg all the time
