Heat treated dynavap too much! Still safe to use?

[terpojones35]

Today on my day off I tried to heat treat my dynavap m body and titanium components with a propane flame torch. I got some light colors but I went a bit too long on all of them. They have a dull and dirty color to them now but are still smooth and fit together perfectly. I’m wondering if they are still safe to use because of how much I overheated them.
Is it possible that I removed a layer of metal or that I’ll be breathing in dangerous materials?

Aluminum is nasty stuff to overheat or expose to acids. Can turn black. All beer brewing sources say avoid aluminum because of this, and if turned black--definitely don't use.

(listen to the pod cast, Five Star (makers of PBW) CEO speaks negatively and with great concern for aluminum)

I think titanium has aluminum in it. Not sure. But worth figuring this out just to be safe if you ask me.

It was heated until glowing and all the parts have a matte look to them now. None of them are black, they are just gray and have no shine left.

Everything still functions perfectly.

Its not aluminum. Its either Ti or SS. It should be fine and no, you didn't melt metal off of Ti or SS with your hand torch, IMO.

Yeah it was MAP gas canister in a hand torch, I was just curious because I did heat it up considerably hot multiple times. I knew the components would still fit but I just got paranoid in terms of what would be left on the surface and during future heat cycles.

Oxides, that's what left on the surface. And yes there are some ongoing questions about Ti-oxides safety, that's why for instance, and amongst other reasons, we all recommend to never use titanium coils in heaters in unregulated setups (ex: power mode in box mods etc)

But what was your initial goal? If it was to change its color you should have better looked into anodizing (i.e. using electricity)

You could try polishing or lightly sanding the surface to try to remove some of unsightly layer maybe?

My goal was to produce a sort of rainbow/galaxy type look. The heating process produced first gold, then purple, then blue. After those colors, it would heat to an orange glow and leave behind a dulled gray color. I knew that the device would still be functional considering the insane ruggedness of Dynavap products, so I wanted to see what would happen if I went multiple times heating to a glow and then cooling down in water. It has a really rugged and industrial look to it which is pretty raw, my main concern was just safety with further use.

The body was a 2018 M with an xl condenser, spinning titanium mouth peice, and a titanium tip. So both titanium and ss were used.

Nothing bad happened to me

nothing bad has happened to me either!

Either via electricity or heat... anodization is anodization. Ti oxide is white/grey dust.. It can be removed manually ,the colors can be removed via chemical solution https://www.finishing.com/91/78.shtml... i suggest to try to polish it as much as possible with a magic sponge. I cant see the condenser but it looks fine to me on the outside.

Just look up a color temperature chart and corresponding oxidation colors.
Takes all the guess work out and eliminates any potential health concerns.

Arrived on this discussion in the same idea as the answer given by Kerozen wich is a question I have often asked myself, being a medical user with breathing difficulties.
My two dailydrivers are the Lotus and some VapCaps, often at high temperatures, and both suffer from oxidation of the most exposed parts

Steel does that.
