What metals are bad for high temp inhalation?

So, I'm looking to make a type of vaporizer that I can put directly onto bud in a bong with an electric current heating element to burn it instead of using a lighter.

What types of metals should I avoid that may be toxic for single or repeated use? Also does anyone have any good starting points for this kind of project?

-Thanks

Welcome to the board.

You mentioned the word burn, which is combustion and is generally seen as toxic in itself around here, hence the URL of FC.

Sorry I can't help here. Good luck.

Well it won't be vaporization. People use magnifying glasses and solder irons to avoid using lighters for combustion. Not sure on what the metals found on soldering irons would be. There's also hemp wick. Maybe a Persei+ hammer top if you want to splurge. Honestly though it will be a pretty negligible difference.

You might start here. This thread is an oldie but a goodie: http://fuckcombustion.com/threads/vriptech-heat-wand.282/

Salutations Xathix,

Hummm... Would the power of fire (or so) suit your needs?



Though i guess no combustion is actually intended, of course. Or it wouldn't be a vaporizer as we usually think of them anyway!

Anything that generates emanations within the operating range. So i sort of wonder because there's a type of metal known as Curie alloys which heats up fairly quickly then it stabilizes around a "Curie point"; lets see a chart:


In addition those are real-world values (from a commercialized product):

...and this is a probable metalurgical formulation candidate:

According to my sample selected above it seems target thermostatic cannabic vaporisation temperatures correspond to the lower Curie-effect range (red), so are there any fumes emanating from such alloy at 190 °C? If not that could mean we can have a new type of "conduction" mode, one without the typical burns...

Well that's certainly a question i got somewhat on my mind too.

Good day, have fun.

People seem most concerned about brass that contains lead, as well as aluminum. However there is data that suggests that even at combustion temperatures, these metals don't offgass.
