Nautilus BVC coils and burning taste

[Arukas]

My first pack of BVC coils lasted me about two weeks, although some of that was user error - I ruined a few coils by putting them in and immediately vaping at 12 watts, apparently you need to start low and "ramp up" the wattage to break the coils in. I don't know the science or mechanics behind this, but I've seen this recommended a lot.

So I got some new coils a couple days ago, and last night as soon as I went up to 13 watts I started experiencing a burnt taste. I went back down to 12 watts and there was still a slight burnt taste but it went away over time.

I'm curious why this is happening. Why am I getting a burnt taste around 13 watts, and why will it go away over time. Is it unsafe to continue vaping a coil once it produces a burnt taste? Am I inhaling burnt ceramic wicking?

Ok there's not enough info to help you, so I'm going to ask a few things. Did you PROPERLY prime your coil? After Priming did you wait 10 minutes for the juice to saturate the wicking material? What is the VG/PG Ratio on your juice? And is it crappy juice that somebody sold you at a B&M or something you know is good quality?

Dry wick. Juice it up.

I have been vaping on this coil head for a couple days so it's properly saturated. PG/VG ratio is 60/40 and the e-liquid is from Vape Wild. The e-liquid is described as a "tank cracker" which I figured wouldn't affect me as the Nautilus Mini is a glass tank. Can "tank crackers" have negative effects on coils? I'm just wondering why the burning flavor was temporary and if it's still safe to vape even if the burning flavor faded away.

Not a dry wick.

With higher PG blends you want to run it at a lower wattage. Try it lower and see if the taste changes. PG vaporizes at a lower power then VG. VG is usually what you use higher power devices on in order to create bigger clouds and to vaporize the thicker liquid. I don't do PG blends but if your running it at that wattage your coils/wicks are getting burned out because you are vaping the thinner liquid so fast the wicking material can't keep up with the chain vaping, causing the wicks singe or burn.

Turning up the Heat

If you’re looking to really turn up the dial on your volts or watts, VG has a higher resistance to heat, so you can really crank it up! PG is a bit more sensitive to heat, so the taste of higher PG based liquids might taste burned if you’re vaping at higher volts/watts.

Taken from PG vs VG E Cig Juice: What are they, and how do I choose the best PG VG ratio? - onVaping.

Depending on your ohms, some juice doesn't like higher powers. There is no wrong way to vape, just do what you think tastes good and don't get hung up on the numbers too much.

Some flavorings burn at lower temps than others, you cant vape all flavors at the same power levels.

Burnt tastes can come from wicking material or juice flow unable to keep up with how fast you're vaporizing the juice, sweet or dark or thick liquids wick slower, gunk up coils and burn easier, too much power or to much for flavorings used in juice, too much or too little airflow.

To me it sounds normal, in your particular set up (delivery & power device combo) that specific juice burns at 13w and above and doesn't at 12w and below.
If the burnt taste went away after you turned down the power, vape on.

 

[Madcuzbad87]

Topwater are you sure? Hes using a 60% PG blend. I'm pretty sure that 13w+ is way too much for a moderate pg blend. If it was 60% VG I could see it being vaped at 13+

Try closing down the airflow a little. This will place more vacuum in the atty head and improve wicking. IMO 13 watts on a clearo is nuts but that's just me.

 

[Madcuzbad87]

Lol EBates, the Nautilus mini with an 80/20 vg/pg at 16watts is not bad. Also SuckMyMod did a video on the Nautilus Mini at different Wattages. He go a warm and dense vape from 18watts but 20watts was WAY too much.

 

[Arukas]

What makes 12-13 watts "bad" on a Nautilus Mini? What separates it from vaping something like an Atlantis at 50 watts? I can't imagine I'd actually be burning the e-liquid given how high some people vape and I never thought of 12-13 watts as being high with the 100+ watt devices out there. I do like that range though as it gives a warmer more flavorful vape. The vape just isn't as good below 12 watts or so. Of course the "sweet spot" changes depending on the e-liquid. One e-liquid (Gogo Lychee from Ready Set Vape) was actually best to me around 15.5 watts.

Still curious about the original questions, what was causing the burning taste and if it's harmful to continue vaping it even if the burning taste goes away. I can vape the same e-liquid right now at 13 watts and get no burning taste, so if it was the e-liquid burning I don't understand why it burned that time but not this time.

The blend of juice..... as stated in multiple other posts. And if I had to guess why it did it for a certain amount of time and was fine later is this. You bruned juice on the coil, you changed the settings to a lower wattage and burned off the gunk that you previously burnt at 13watts. And because you were vaping at a lower wattage later (the 11 Watts you brought it down to) it wasn't burning anymore. Vaping at 20+ Watts is not for people using PG juices. Most vaping at 30+ watts are using 70/30 vg/pg, 80/20 vg/pg or or MAX VG juices. Very rare for anyone who is vaping at 30+watts to be using 50/50 or higher pg blends.

I use 9.5W on the mini's BVC coils and never have a problem with dry hits/burnt taste. Turning the power up to 12W and higher with a 70/30 pg/vg juice can start to give a burnt taste for me.

 

[SweeneyTodd79]

Gonn try to clear up a couple things

1) 50 watts REQUIRES a SUB OHM coil. Stock BVC's are not sub ohm.

2) Like MadCuzBad said, the mix determines how fast somehting 'scorches'

3) 12 watts is not better or worse than any other wattage - I go between 8.5 and 13 on a 1.2 ohm coil to chase flavors.

4) No one has asked - what nic rating are you using? going from normal to vertical coils makes more vapor but let me tell ya, too much nic and it will taste burny-awful.

 

[Topwater Elvis]

I vape 50/50 non sweet, clear juice with a 1.8 bvc at 12w - 15.5w every time I use one, never have any problems with dry / burnt hits unless the head is bad.

 

[Stretchman]

Put a couple drops in the top of the coil, then do some dry pulls without hitting the fire button, until you see a bubble or two in the tank. Let it prime for a bit, then try and fire it. If it gurgles them you can clear it by gently blowing through the stem while firing.

Do that at lower power.

Get the 1.6 ohm coils.... don't throw out the old ones though, dry burn them at the highest watts your device will put out for about 40 pulses at 7-8 sec. Each then give em a try. If it still tastes funny dry burn then boil for 20 mins. Then let dry for 4 days. Bvc coils are ceramic. They will take the heat.
