Titanium hardware question

[Classic vaper]

I obviously know that anodised titanium caps are non toxic to vape on. I recently removed the anodizing on my titanium rda cap and now its bare titanium. Instead of re-andozing it I was thinking about changing the color by heat method instead of voltage. Would this make it poisonous? I don't know, that is why I am asking. Any help is acceptable

Your titanium cap was anodized?

Titanium Dioxide, which is toxic if inhaled, begins to form at ~600°C

I don't think there's much difference in the end result. "Anodizing" titanium creates an oxide layer, regardless whether it's done with voltage and a borax or acid bath, or with a torch.

Yes. I removed it with a buffing wheel

Sooo... my cap was toxic to begin with?

Here is the before and after

Nope, not as long as the oxide layer stayed attached to the titanium. All titanium will form an oxide layer. The question is whether that oxide layer is thick enough to produce an optical interference fringes that make it colorful.

I also think the notion of titanium dioxide being "toxic" if inhaled is overblown. The NIOSH limits for occupational exposure are not particularly low.

I don't know .... about this but my Venna TI Black came heat treated. So I assume it's not toxic. And it's beautiful (colours are not edited):

Correction: Temperature needed to change the colour of titanium is in the 600°C to 700°C range. Titanium Dioxide begins to form at ~1200°C. Seems I got my facts backwards (drunk again!!)

And @dom qp – that is a beautiful RDA
