e-liquid darking

[Carterjonr]

Quick question. Does anyone know why my e-liquid progressively gets darker the more I refill my tank. Same goes with what is left in my bottle.

As the juice oxidizes over time it changes colors, becomes darker. In the clearomizer the juice will turn even darker due to the heat of the coil. It's still good juice.

I find that a lot of my juices get darker as they age in the bottle. Same with what's in my carto tanks, my salted caramel starts out on a clean tank with a very light amber tint but a week later when I get down towards the bottom of the tank it will have almost a dark coffee color.

Interested to see if there are any scientific answers to your question.

I believe that it is because the coil and wick gunk up as you vape through your liquid. The gunk leeches out of the atty head causing the liquid in a tank to become darker, or at least that is my understanding of it. I'm sure someone more knowledgeable will be able to chime in. Hopefully that helps though.

yeh, if you refill more than 3-4 times without changing coil you'll end up with a burnt wick that turns the color of the liquid in your tank brown. long story short, replace your wick so you can get a fresh vape experience and not ruin your not even vaped liquid. lol

Sadly, any tank you buy that isnt rebuildable is only going to take you so far.

Scientific answer....it is called caramelization.....PG in a way is a sugar, it metabolizes as a sugar and browns as a sugar. Caramel is browned/burnt sugar. The coil build up over use turns dark then the color migrates to the wick then into the liquid.

Oxidation is what is happening to the liquid in the bottle, for some it never does it, others it does.

For personal experience, place a few tablespoons of sugar/butter in a saucepan, heat and stir until it turns brown then pour it over your favorite ice cream, you just witnessed caramelization!

I was just trying to keep it simple and didn't realize you wanted a more in depth answer.
