Made a bunch of bottles last week, and all of them are different colors, some are getting a strong orange hue, some a weak one, and some are staying clear even after days. I know this is the nicotine, but why does it vary like this? Are the darker ones more oxidized?
Could be flavors, could be nicotine, could be interaction between them. There are lots of variables here. Without knowing the recipes, it's hard to tell.
Sunlight. The ones that get the most sunlight will oxidize the quickest.
Huh. They were all stored in the same position though. So does the darker orange color mean its more oxidized?
Nicotine has a lot to do with it. I accidentally added some 24/100VG nic to a 120ML bottle that had just a little bit of apple pie left in it. BOOM! The whole thing turned dark orange in a matter of minutes. I haven't used that bottle of nic yet, but I still have it.
