My oven only goes to 500F. Some go to 550F. Even Ooni's are 1000F at most.

What does yours do?

Well most oven won't burn any your cookware no matter the material.

I just wanted to emphasize that there are danger below 3,000F.

>won't burn any of your cookware

Except PTFE coatings, which releases toxic gases above ~260°C/500°F

except this post was originally about titanium.

I'll bear that in mind the next time I decide to make lasagne in a crucible

It's grade 1 unalloyed titanium from Snow Peak: https://www.snowpeak.com/blogs/explore/ultralight-everything with the lowest oxygen content. Your hazard warnings are noted though, and I definitely will keep it at lower temps.

I've also got their titanium flask. I had it engraved from a random guy on youtube who had experience engraving on Ti, because everyone else I contacted (mostly jewelry shops) could only anodize it.

If there was a way to bend this particular exchange into the style of the article, I would. Its definitely in the same spirit.

This sounds like a job ChatGPT would excel at :) I will leave actually doing so as an exercise for the reader.

I'm pretty sure titanium dioxide is pretty inert. It's a primary ingredient in sunscreen and diaper cream.

Otherwise, I agree with your point.

Outside the body is one thing. The EU banned it as a food additive last year and some US states are considering it too. TiO2 has genotoxic traits, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8323234/

I always found it odd that my acrylic paint and my toothpaste share this ingredient.

Dihydrogen monoxide too!

Water isn't genotoxic. Titanium is. It's fair to be concerned about chemicals when the chemicals cause objective harm.

Correcting myself, I was thinking of Zinc Oxide. But it's still pretty inert. I wouldn't want a plate of it, but whatever level of toxicity it possesses, it is low enough that it requires careful study to detect.
