I bought it to try. It did not stand up to the firing test. You have to scrape off the coating for the positions and negative connections. I still got a hot spot at the top. As soon as the hot spot showed up the rest of the coil went to crap. I was using it on a completely unoxidized wick though.

I think people are waiting to receive their pyrex/FQ tubing. But a few creative minds are already looking to take it to the next level.
Oh we are, it's just no one has had the chance yet as the tubing isn't in yet. Dan got the jump on us publishing just before the Thanksgiving weekend leaving us to ransack our own possessions and ideas. At least, I haven't got any tubing yet....
Some are speculating on variations of Dan's method that hopefully overcome some of the heat lag.
I still like the idea of ir laser diodes to replace the coil.

Like others I'm impatiently waiting for glass.
I haven't seen an update from Dan on how his trials have been going. I hope that means he is lost in a blissful vapor fugue state
I gave up on insulating/protecting the coil for now as Dan indicated that he had tried it a while back and it didn't seem to make a difference. That and it would only complicate the process.
Its great to get information flowing from glass experts. Seems like there might be a little controversy between pyrex/borosilicate and fused quartz. But I like the idea of having the final product polished and annealed.
Maybe someone like Wharf Rat can hit up his glass expert and get some input on what they think the thinnest wall tube we could use would be and how to go about getting some. Just pulling from the rear end here....But I'm thinking the thinner the glass tube the faster it heats up as well as more heat transfer from the coil to the tube.

The same study also showed that in the group of risk takers that died from their risk taking, brain activity was negligible or none...
Caution Re: 'enamelled' wire - although I've never had a piece of kanthal of the mentioned type, every single other piece of enamelled wire I've come across has not had a true vitrious enamel, rather at best a baked-on high temp. 'varnish', for a slightly more descriptive def. - even the really high temp stuff would produce a flame when heated above failing point and 'burn' off.

Monty, that is a bummer, I was looking forward to taking you up on your offer. I can't get a supplier that deals with small quantities or non business customers.
Thermal Properties of Fused Quartz
One of the most important properties of fused quartz is its extremely low coefficient of thermal expansion: 5.5 x 10-7 /°C (20-320°C). Its coefficient is 1/34 that of copper and only 1/7 of borosilicate glass. This makes the material particularly useful for optical flats, mirrors, furnace windows and critical optical applications which require minimum sensitivity to thermal changes.
A related property is its unusually high thermal shock resistance. For example, thin sections can be heated rapidly to above 1500°C and then plunged into water without cracking.

Somewhat due to waiting for glass and the issues/risks/lack of understanding that go along with glass I would like to re-visit the discussion of a different material for the tube.
Something like copper that is considerably more thermally conductive (attached is a TC list I copied from the engineering toolbox) with some type of vape safe thermally conductive non-electrically conductive coating.
Yes, I know the last bit will be the challenge.
I think there is a lot to be gained by the use of the tube to evenly distribute the heat to the wick, as well as eliminating or minimizing the oxidation process, plus the ease of changing wicks and etc.
I think something like a thin copper or other high thermal conductive tube will be far more efficient in time to heat as well as heat needed.
Again this all falls on a vape safe coating and unproven theories

I have another source that I will poke tomorrow.....
Not sure, but I think I've read that you should not have copper in contact with eliquid.
OK. Here's an enamelled coil...
Here it is threaded onto an unoxidised wick...
And here is the initial firing with no shorting...
I heated the coil and dipped it into the enamel powder about ten times to achieve this coating.

Yeah, copper probably not the best choice, or would need to be completely coated.
You should not practice this
without considering safe measures
Have fun and be safe

Did you try putting any juice on the wick to see how well it vaporized?; can't tell from the picture. Also, it might be good to do some repetitive firing to see if there is any degradation of the coating over time. Looks very promising.
Nice one Slopes! If you anneal it I heard it should be raised off the kiln or oven floor to prevent dimpling.
Maybe, if you made an atty cap with a bunch of mirrors around it; you could hold it up to the sun... Archimedes Death Ray atty
