Directed to all, not just our friendly host:
Not to be a pedant, but this part is right, some of the rest is misleading. Light we see ranges from roughly 400 to 750nm in wavelength, to first order “size.” Unlike a gigantic star (which significantly, is an emiitter, not a simple reflector like dust or fog), however far away, a 25nm dot or even a film (which we can see when thinner than the wavelength due to interference effects) will not scatter light that we can see…25nm is xray territory, we can’t see it. That said it has little to do with vaping or the overarching point(s). I’m a light guy, had to chime in.
Titanium is so reactive with oxygen that it is, or perhaps just was, used as solid rocket fuel by the Russians. You can put it in the most pristine vacuum that humans are capable of producing and it will still form an oxide. That oxide is so impervious and well attached to the underlying metal that it prevents further corrosion very well…you don’t need to paint titanium to keep it from rusting…even titanium exhaust headers don’t rust (they do turn beautiful colors.) The point is, the TiO2 ain’t coming of for you to inhale PERIOD. Finally, go have a look at the ingredients listed on your toothpaste tube or nearly any food article that is a brilliant white color. Right there at the end of the ingredients list you are almost certain to find titanium dioxide.
Please, let us stop the misguided fear of titanium. Im not even worried about the flavors that much. If anything I’m inhaling significant volumes of a pretty good organic solvent, PG. I am nearly 100% organic, save some titanium of my own, and just a tad worried about that one. But, even PG vapor/aerosol has been studied a fair bit and it’s deemed merely a nuisance by the trusty old US government.
To be clear I’m not ranting here or directing this at any individuals, just spreading a little knowledge.
