The ultimate low toxin coffee brewing vessel is a borosilicate pressure siphon.
Kazumi Siphon Coffee makes the leading vessel AFAICT. It's a delicate piece of engineering, beautiful, and requires a lot of tender care.
Using a pressure siphon eliminates the need to heat water up in a kettle, which reduces toxic load as much as you can.
All glass everything. No filter.

Yes, we love siphon coffee for drip. There are smaller glass ones that also use a infrared light as the heating element. We use the spiral tubing on the kyoto cold brew system. One drip at a time travels down the spiral.
For example?
Here is an example
Cold brew. Both these tools feel like a chemistry set in the kitchen.
Yes, you can also get an red light to heat this instead of flame on the stove.
Problem with most siphons are: 1 still have metal beads and 2 still have cloth filters.
If I'm going to this much trouble I want all glass no filter.
I get that.
Yes. Tradeoffs everywhere for me. The kazumi is all glass, but capacity is low, too tall (it seems), and the spiraling glass tube would be interesting to try to clean. The Yama glass siphon ones are larger capacity, not too tall, easy to clean and store away, but you have the metal beads and spring mechanism. Cloth can be replaced with screen, but again metal.
$200 isn’t a bad price either. People spend way more espresso machines.
Very cool. I learn about this yesterday, an all glass pour over solution - https://pureover.com/
