My e-juice cooked down to goo

[tmoore]

Just the past few days I upgraded to clearomizers from basic, black 510 cartos. So, now i can see my e-juice.
One of my flavors went from relatively clear and thin in viscosity to a dark thick goo as I vaped it down.
Is that a function of the wattage I vaping at, or is it just characteristic of some juices? Is it something else?

TIA

Most likely a combination of the two. Here's an analogy for you: you simmer something on the stove. As it simmers, it gets thicker and cooks down. Your juices are made with a several different ingredients. Some wick and "cook" faster. What is left is the concentrated ingredients that didn't cook off at the same speed. You still get all the ingredients while vaping, they just wick at different efficiencies. PG is thinner which will travel up the wick quicker, while VG takes longer to wick.

Hmmmm I think that actually makes some sense.

Light bulb moment! Which may explain why some say that Nova's mute the flavor for them.

Not all juices get significantly darker but most will darken somewhat.
