hmm, I need a chemist. wire help!

I used to be a chemist.

Pure chromium is in an oxidation state of zero though there will be a surface coating of chromium oxides of varying oxidation state depending on how the wire has been made and treated. However, when heated in an atmosphere containing oxygen it will oxidise. If there are any particles released then some of these will be in a high oxidation state. You really, really, really don't want that in your lungs.

I'm not sure of the chemistry and physical behaviour of chromium at pretty high temperatures given the resistance you want. Just google high temperature behaviour of chromium wire. If there is any evidence of surface erosion at all after heating (Using a microscope before and after) it is not safe to use.

Personally I wouldn't use the stuff and I'd be quite happy handling pure nicotine or hydrogen cyanide gas.

Good to know. I was only thinking we had most areas of expertise covered on POTV the other day, -except a chemist ....

Dispute all the warnings I reckon our resident mod destroyer will try it someway or another. He needs a strict talking too by his mum. Miss Pepper

Hydrogen cyanide now you're talking !

It is used a lot in labs. Very handy stuff for dissolving metals in. You fiddle the pH and drop out the metals you don't want. There is invariably gas evolved.

He doesnt listen to any of his forum mom's (he is at that age ) because if he did he would have told me he was running out so i could send a SOS pack down!! Instead he just causes us daily concerns

He needs a good slapping, no better not at that age he would really , really enjoy it. I was going to mention across knee, but that would definetly set him off.

having.issues breaking the 0.07 barrier

the only issue you should be having with the 0.07ohm barrier is staying the fuck away from it

There cannot possibly be a large enough improvement in vape quality going much lower than maybe 0.2 to offset the vastly increased risk. There is such a thing as the law of diminishing returns.

You get one set of lungs Raguri. You're young, but not indestructable. For gawds sake stay safe.

You could always suck on a venting battery rags. I reckon the quality of vape will be about the same and probably only a little bit more dangerous!

Fiiiine I won't use it... HahaHa. I'll just twist 10 bits of 0.2 together .
Thought it was best to ask first, and obviously now bloody glad I did! I am a Nutter, and I know that Sony's can take a fair amount more than 30 amps for short bursts... so 0.07, is actually very safe... 0.04 however is pushing the boat out a bit but still safe for 3 second bursts .
The chromoly wire will be put away for something else... maybe a nice display piece or something... was thinking of making a stand with a working.coil acting as a light.. Then again if the fumes are that bad, maybe I should just throw
