. Just wondering, did you use any method to clean this wire or just straight off the spool?
Straight off the spool.Could be better indeed
Sorry for the bump, but I've been really interested in this dry burning issue of late. I didn't even know about the juice leftovers on the coil until I read this thread but I'm more curious about the oxidation of the metal. It's my understanding that most on this thread are of the opinion that dry burning a kanthal coil a few times during its life is ok because of the alumina layer. Am I correct?
And what about dry burning nichrome? Or specifically, a kanthal/nichrome mix.

I would be interested in seeing fresh wire that has been wiped with alcohol. Also curious about used coils that have been rinsed before dryburning, then rinsed again. Perhaps after a week of use.
Alumina is a ceramic material. As such it's non-conductive and so an (short) insulator of the circuit if in close or direct turn contact. It further isolates the vaped product from reactions with the underlying metals including deterring ferric oxidation. Why Kanthal gained respect and popularity several years ago vs. other wire options we see today such as Nickel. Many noted that oxidation curtailed the metallic taste many with NiChrome. Oxidation no doubt plays an important part in this. All this however when the appropriate methods are applied to ensure adequate and uniform development of oxidation. A perfect complement to the contact coil optimally stabilizing its powerful geometry.
Good luck all.

So do you believe dry-burned nichrome 80 is not healthy? Does it form its own protective layer? I know it turns different colors because of some hexavalent compound that is carcinogenic.Alumina is a ceramic material.

A great bit of information on wire properties may be found on the thread...The end of microcoils?...where Alien Traveler, the OP, and others made some outstanding contributions.
I don't know about about a single compound that turn wire we use different colors. Rather wind temperature and the resulting type of oxidation that's produced I think.
Nickel I've read has the lowest threshold for potentially interesting change of the wires I've studied. Certainly well within the range of power we can apply in preparation. I personally wouldn't dry burn or anneal Nickel at the power levels I consider safe for Kanthal. Many do I believe thinking it can or should be handled just like Kanthal. Good that you ask. Several temp values have been suggested on the above thread.
N80 develops predominantly a chromium oxide layer I understand. It doesn't share the insulation advantages of alumina. So I wouldn't recommend it for contact coils. Annealing may help add rigidity to NiCr coils and same can be accomplished with strain to ensure symmetrical durable open winds. Main wire options we use can all release oxides in torching or pulsing. Care should be exercised and an understanding of the temps likely to release them. I advocate low voltage pulsing for annealing or oxidation and have posted on this elsewhere. Not much is needed to make a stable functional coil. I'm talkin' fundamentals here. We do all kinds of winds in vaping and I along with the many.
Reason I quit was due to the advent of Kanthal as a wind solution and super_X_drifter's intro of the microcoil. It oxidizes safely and predictably at reasonable power levels But we all have to do our own due diligence and determine what risks we're willing to undergo.
Good luck jj. LMK if I can be of any help.
Thanks for the reply. I ask about nichrome 80 because ever since I started building claptons and what not I bought a lot of n80 because it seems to really be the popular choice for advanced builds. I still have so much left and I don't want it to go to waste. But yeah, when I use it they are definitely contact coils. Usually, dual parallel with outer wraps of some really small gauge kanthal, hence the fused clapton. And I do usually end up pulsing them red hot several times to work out the hot spots. The end result is something like this in color.A great bit of information on wire properties may be found on the thread...The end of microcoils?...where Alien Traveler, the OP, and others made some outstanding contributions.

And I'm sorry, you said reason you quit. Quit what?

Tks for the ack. No worries, my bad. Meant quit smoking.
Yeah worthwhile for peeps to look at the temp point where wire/wick/juice start to misbehave. Lot of changes to vaping in the spring/summer of '13 as clearo's were starting to really take off. A lot of genuine interest and real research in the community. This intrigued me after a layoff of interest for a few years. I decided to quit and join ECF when the microcoil arrived. This fascinated me as I knew about some of Kanthal's properties and felt this needed to be better investigated. Felt I could make a contribution. That stable basic electronics could really help new vapers including yours truly have a better chance of succeeding. Two years later and I'm still here. Tension winding of contact coils has gone around the world.
I worry not too much that folks know who introduced the adaptations of a contact coil or strain winding. But jj like the microcoil I am concerned that it's advantages and how to use the wires as proper circuits is not at all well disseminated or understood. Wish more were referred back to super_X_drifters original thread Micro Coils to increase Vapor, flavor & TH | E-Cigarette Forum and offshoot threads on the micro. Surpised it doesn't even return on the 1st page of a search despite being one of the most successful threads on ECF and the launching point for the contact coil, tension winding and incredibly useful adaptations like KGD.
Am I surprised then to see an accomplished winder such as you not up on Kanthal oxidation's potential advantages?
It's a huge community on ECF for new vapers to transit. And the Autobahn is out of sight for all the winding dirt roads we all carve out of these woods.
Hope we find our way out.
Good luck.
