Just to mention:"Hmm, there seems to be a titanium-heater in the herborizer?
Over 610°C titan frees up titandioxide, and this stuff is bad for your health (risk of lung-cancer when inhaling).
And the herborizer reaches that temps easily? They tell you to use over 600°C for "free-burning", this is not the temp of the air, but of the heater."
To clarify again, titanium dioxyde is what give titanium low oxydation after geting covered by.
Titanium dioxyde is used as food colorant E117 (like in M&Ms etc...)
Mars did invest over 1 Million Euros to develop a new coating-procedure to get away from Titandioxide as colorant for their M&Ms in 2019.
In France it is forbidden to use it at all, in Germany and in the whole EU soon, too.
This is how "secure" it is.
And there are older studies that show particles of the heating-wire in the hot air of heat-guns. The outer microscopic coats of the wire fall off because of the thermal expansion of the material. They are not made from titan, this is just to clarify that simple thermal expansion in usage can make tiny parts fall off. This is why they wear out and need to be replaced from time to time.
I don't say, THERE IS TiO² in the air of the Herborizer, don't get that wrong.
No one can tell unless being tested in a laboratory.
And to be honest, i don't think there would be found noteworthy ammounts.
But i am not 100% sure, and this scares me (personally) enough to not risk using a Ti-Heater myself.
That doesn't mean, anyone else shouldn't, too! But i wanted to get clear what i meant and why i wrote that.
No offense, just to clarify, english is not my native language (not even near that^^)
