So first off, I'm new here. I've been vaping over a year now. I use a Delta 2 (rba Deck) with an ipv4. I recently started using Titanium Wire and ordered some from someone on Etsy. It's grade 1 pure titanium wire, or at least advertised as such. It came in a roll with no label and instead of being a dark smooth color it's light gray, dull looking, and rough to the touch. Is this normal? The wire I used before was given to me by a fellow vaper and it looked and felt closer to Kanthal. There's no flaking or roughness when I've tried to scratch it or clean it with anything, but the look bothers me.
