Attention Ti Users: Titanium dioxide carcinogenic

On the topic of butane, would it be possible to make the oil with CO2 or another safe solvent?

I've heard of people using hexane before to do the same thing but that's extreeemly expensive and hard to find. Plus I'm not to sure how safe that is either since I known it's used in industrial applications to dissolve glue.

With 4x+ refined butane you shouldn't have many impurities in it so when it does all evaporate it shouldn't leave anything behind. I think vector and colibri are either 6 or 7 time refined and are supposed to be the cleanest available. As long as you use good butane and make sure you purge it long enough that all the 'tane leaves you'll be fine.

Of course heating pure titanium with a butane torch causes an oxide layer to form. See those colors on your Kabley nail or Ti pad? That's titanium dioxide. Color varies depending on the thickness of the oxide layer. Am I worried about it? Nope.
