Nice video...
So it doesn't look like the wick in That particular E2 carto design seem to burn when Dry. Let’s hope that the new revisions all come with that type of wick. What is the wick made out of?
BTW – Just as a test. What would happen if you do the Exact same test on a wet wick?
It would be interesting to see what the results of your test with a wick that,
Has been soaked in pure PG for 30 minutes
Has been soaked in pure VG for 30 minutes
Has been soaked in PG/VG for 30 minutes
Has been soaked in PG/VG flavorless, colorless e-
juice for 30 minutes
Has been soaked in PG/VG flavored, colorless e-Juice for 30 minutes
Has been soaked in PG/VG flavored, colored e-Juice for 30 minutes
Has been soaked in pure PG for 24 Hours
Has been soaked in pure VG for 24 Hours
Has been soaked in PG/VG for 24 Hours
Has been soaked in PG/VG flavorless, colorless e-Juice for 24 hours
Has been soaked in PG/VG flavored, colorless e-Juice for 24 hours
Has been soaked in PG/VG flavored, colored e-Juice for 24 hours
If the wick material isn’t melting, then it would seem that the candidate for the bad taste is the “gunk” on the wick. So the effort shouldn’t be concentrated on the wicking material but finding out what is in the gunk, what makes it form, how to stop gunk from forming.
My belief is that Colorless, Flavorless, Pure PG based juices will form less “gunk”. They will also be less likely to make an E2 carto (or atty) develope a bad taste than High VG, colored and flavored juice.
If that is the case, then there might not be a solution for people using High VG Colored and Flavored juices with the current E2 design in regards to eliminating bad tastes.
