You did it, Bloke! You "made" me order titanium wire from zivipf. Now the wait for the mail
Then why order all the way from Germany?No, the great Nanny State of NJ.
Indeed. Exclusively so for almost a year now.Rossum, you're a squonker guy, right?
made me laffI keep thinking about a Reo, but never pull the trigger.
I went back looking for suppliers and saw where Bloke had ordered from. I also have another one, US based I think, but went with zivipf based on Blokes glowing reports of high quality. That way if it goes wrong I can blame him, LOL.
There will be such a beast in the near future via Cloudmaker Tech. Modular and open source software also. I'm waiting impatiently to throw my money at them.OK, I'll blame Tony instead if it goes wrong, LOL.
I'm sitting here with five DNA boards and a DNA clone mod at the moment. The boards are still waiting for me to get properly motivated and build/convert things to install them into but the clone, Invader Mini, is working very well. I'm invested a little too far in DNA at the moment to spring for yet another, pricey at that, mod so I'll just have to lower the temperature and look for the best performance.
Anyone know if there's a squonker out there with TC and adjustable temperature coefficient curves?

Oh thank you very much [emoji14]OK, I'll blame Tony instead if it goes wrong, LOL.

I bought into rayon, have a 3 pound box of the stuff.... Went thru silica, ekowool, rayon, cotton balls... Japanese cotton has outperformed them all for me, in taste, wicking, ease, etc. I can't imagine koga being any better than KGD or muji (or is it Fuji? ), cotton bacon, etc... I'm pretty satisfied with Japanese cotton (KGD & "muji" which look and work exactly the same for me)
The colors are interference colors which result from the very thin initial oxide changing as the oxide grows in thickness.....and the colors you see are related to the wavelength of the incident light. So the color is sort of related to temperature...but it also changes with time. Another factor that can confuse it is whether their are reactive species such as organics etc. in the air or if there is anything at all on the titanium surface that could contaminate it.That is a very good idea When Tony first mentioned torching I immediately thought of the stove, don't know why I didn't think of the oven! It would take a bit of experimentation - I have no idea how much heat I am adding with my pulsing or Tony with his torching - but once the right temp was found it would be easy to do a whole spool at once if need be. My oven does up to 300°C I think, at least in the high 200s anyway.
Actually this reminds me of a question I had: do we know exactly what triggers the colour change? Specifically, will it change to a each given colour only at a specific temperature? So eg if it ever reaches 100°C it changes to Colour 1, at 200°C it changes to colour 2, at 300, colour 3 etc, and it doesn't matter what temperatures it reached before. Such that (in this made up example) heating to 298 then cooling to 20 would be no nearer to putting it in Colour 3 than just not heating at all
Or can it be sort of "pushed" along the scale by repeated heatings at lower temperatures?
So if I pulse at 30W, I first see it turn yellow. What I don't understand is, if, once it's yellow, I then let it cool completely, has that helped at all in getting it to blue? Will a yellow wire now reach blue sooner/cooler than a base colour wire? Or is the fact that it's currently yellow completely irrelevant for it getting to blue, because it has to be heated up to temp X to get to blue regardless of how much it has been heated before (without reaching X)
I am not explaining that very well but I hope the question is coming through. Clearly the colour states are different from say, the states of gas/liquid/solid, where a substance can be taken from its gas state to liquid to solid and back and forth, and it depends only on the current temperature. The titanium, once it has changed colour, stays changed - getting to a certain temp once permanently changes its state.
So I'm trying to understand if it getting to state 1 (yellow) changes the effort required to then get to state 2 (blue)
The reason I'm interested is when I was pulsing again last night with a longer stretch of wire I kept doing short pulses, and eventually got it yellow then eventually blue, but I wasn't sure if it eventually went blue because each pulse helped it get there (even with cooling down in between) or if it was simply that the later pulses were longer/hotter and finally got it to the right temperature threshold. I was wondering if I should have just pulsed continuously until it was blue - if I was wasting my time with those short pulses that turned it yellow, or whether in fact it was all helping "push" it along to blue, albeit slowly.
I believe our 'blue' is the one forming between gold and purple.Heat coloring of titanium:
Pale Gold Straw-385 ºC = 725 ºF
Purple-412 ºC = 773.6 ºF
Deep Blue-440 ºC = 824 ºF
Red Purple-565 ºC = 1049 ºF
Brown Gray-648 ºC = 1198.4 ºF
Green Blue-925 ºC = 1697 ºF
I think it's not going to work in the oven... And as it seems former heating does not help the process. You can just control temp better by pulsing and not let it get too cold between the pulses. Did you try it by temp control mode? If this is true, you won't be able to form the dark blue as it will get temp protected.

When I torch the wire, it starts yellow then blue, then purple and if I keep pushing it, it will suddently change to dull white/grey

Since the change in color with time is slower than the change with temperature I think you could get a reasonable relationship between color and temperature (maybe...sorta) ....but I'm not sure I would trust it.
