VG juice getting darker after vaping in clearomizers?

[burnsmary95]

Now that I can see my e juice, using clearomizers, I have noticed that my 100% VG base juice is getting darker and darker as I vape it. The less that is in there, the darker it gets. Anyone have any idea why this is happening? Is my juice getting slightly burned and then wicking back down? I did not notice this before because I could not see it with the solid casing. I don't think it has effected my vaping experience until it gets almost used up completely, then I just rinse it out, dry burn,and refill because it looks kind of gross when it's almost gone, not to mention the awesome fresh taste of a clean clearomizer... oh, I DIY my VG with various flavors, and low level nic, doesn't matter how light they are at the beginning, it gets darker as I vape.

Juice is affected by heat and light, both of which make it change color and sometimes get darker over time. It shouldn't have an affect on it at all, so no worries there. I have a couple of 60PG/40VG DIY mixes that were very light when I first mixed them about a month ago. Now they're very dark, but they taste even better and vape great!

thanks for the quick response. I do notice that if I chain vape, the clearomizer does get pretty warm. I try to put it down once I notice this, since it's all plastic and rubber around the coil area. I have not had any real problems, was just curious.

I was wondering this myself. I had noticed it in my Boge 510 carto's after about a day.
They weren't burnt and tasted fine. But I accidentally over refilled one and blew the excess and noticed it, dark brown.
After that I paid attention and it occurs in them all if I keep it topped up and don't let them get close to empty and blow out the remainder and do a complete refill.
Weird..

glad I'm not the only one, I guess it's the nature of heating the VG?? I also noticed in my other regular attys that I would blow out dark brown juice say if I flooded it, and had to blow out the extra.

Same here. I actually made a shrink tube sleeve for my clearos, because I don't need to see the juice all the time, and don't find that color particularly appetising. Plus I'm hoping it gives a little shock absorbsion to it. Then I can just slide the sleeve off tocheck the juice level, and see when I'm refilling it.

I noticed it with Strawberry Shortcake, it starts out a light pink and when it heats up it gets really dark almost black, doesn't taste burnt but looks awful!
