@Alien Traveler took some really neat close ups of kanthal wire before and after use with a SEM, and I don't remember them losing any metal from the before and after pics. I'm pretty darn confident we aren't inhaling much of anything. Decide for yourself; he's got more in this thread.Like the title says, how confident are you that vaping using kanthal as a heating element is safe? Theoretically it should be (we heat it way below the vaporization temperature), but are you concerned that trace amounts of metals are inhaled by vaping using an RDA that has a kanthal coil?
Id rather do Kanthal than welding or a welders helper... imagine all the stuff they breathe...

That's for sure. I was a welder for nearly 40 years. Breathed a lot of nasty stuff. I'm not worried about a little kanthal.

I am curious. I have noticed that as I use my coils and they get gunked up, the resistance does go higher. Once I clean and dry burn, the resistance goes back to the original number.Yes I believe there are trace amounts of metal inhaled.
Now, let's define "trace".
Only an assumption on my part, but as we use a coil, the resistance of the coil will slowly increase. The resistance increases because the wire becomes thinner. (higher # gauge)
The coil in the carto I'm using this morning started life at 2.2 ohms, 3.5 weeks later it reads 2.9 ohms. So roughly 1/2 a ohms worth of metal is gone from that coil.

That is telling me that it is actually the build up of material on the coil that is causing the resistance rise and not the wire getting thinner due to sloughing off the outer surface of the wire.
Not exactly a scientific method and doesn't prove anything. Just musing this morning.
I trust what I am doing now is much safer than what I was doing for 45+ years and am not gonna nit-pic every little thing about it apart.
