Thank for trying it!
Not to be rude but There's no way the rayon has a metallic taste... It's the coil. The kanthal wire. Since there is no flavor from the rayon you taste things you wouldn't have noticed before. It's well know that kanthal or Nichrome coils do have a metallic taste to them. You hear more complaints about Nichrome tho because it can be pronounced enough to come through even over flavors. However I never noticed an issue with Nichrome, I actually always noticed a metal flavor from kanthal, possibly I have a low grade or something.
So yes it's so pure that if you are sensitive to the taste of kanthal you could notice it more. And anything that's there because youve eliminated the wick flavoring from the equation allowing all flavors to be detected.
There is nothing in the rayon that would cause a metal taste.. But your vaping off an iron kanthal wire.....?
No reason to blame rayon when you have it wrapped with iron. Don't you think?
Us your vaping out of a metallic device.. Really just goes to show how pure the rayon is.
