I noticed a lot of peoples Ti nails turn a blueish color, almost like an oil slick color. I am using a mini-rig with a very small 10mm Ti nail and while I get great flavor, there is no color on my nail like I see on others. And after about 3 weeks of use I have a lot of oxidation on the nail.
How can I tell if my nail is safe to use?
