and welcome to the insanity atlantis, its a rare day that two newcomers join the crazies in here 
Has anyone tried high desert ecig nic base , it says its made in the USA?
I questioned a supplier recently on his claim to USA made nic and requested his certificate. He freely admitted to just rebottling foreign made.
Seems that's been a common thing in most industries nowadays anyways.
got a numerical value?The inherent acidity ( yes it's acidic)
I found this pdf that gives Euro and USP specs for proplyene glycol.
It lists a testing spec for acidity. To me this means that pg has some acidity.
BUT, I know zero, nada, zip, and absolutely nothing about chemistry. Perhaps some of you smarter fellas can take a look and enlighten me/us.
