Nice to see you,
turn on caps lock only when you're screaming about your successes in chemistry

haha same here actually. Failure is chemistry as far as i am concerned. However, I am learning the more toxic the chemicals are the more likely you are to have success with them. Probably has something to do with selling your soul to chemistry or something like that.

I do it wrong and somethings getting broke....

I'm just the opposite, when somethings getting broke, I'm doing it wrong haha

Speaking of breaking things, ever notice how easily stir sticks break? its fucking ridiculous.

Haha no the kind tidy chemist's are supposed to buy lol
Glass stir sticks = WOMBAT. (Waist of money, brains, and time)

I do that all to often "This won't mess it up to bad"

I actually made a discovery doing that. I was bored and wanted to make sure my concepts were in check so I added Oxalic acid (junk solution) to a recently made calcium chloride solution.

I thought since calcium oxalate is hardly if at all soluble, dilute HCl will be made and the salt will ppt. I added a bit, and it was just milking, I then found a screw driver to see if it bubbled/to stir it and the moment that thing touched it the entire fluff wall of calcium oxalate dropped like a brick. So what I discovered is that: Rusty screw drivers = Magic things to increase precipitation speed of Calcium oxalate! (.. eventually I'll figure out wtf was on that and use it to my advantage)

Fe2O3 is a total bitch lol
Once it is deposited on something, it stays there.

iron oxide = plays a very vital, very serious role in printed circuit boards. 
also iron oxide can be damn useful for making perhaps the ghetto-ist of all temperature probes, as a semiconductor.  propane torch the tips of two copper wires till they're green, twist em up and go.  just how much these two wires semiconduct, and don't semiconduct will be a function of temperature. RTD

Have you done this?! I am very interested in making this.. not for practical purposes, but it just sounds really interesting. Do you have info, or can you write a thread on how to do this?
I'm confused about the copper wires, etc when talking about Fe2O3?

oops, a bit embarassed.
you had every right to make fun of me:)
the reason i confused copper and iron was due to a deeper meta-mix up between RTD temperature probing vs. thermocouple temp probing.......



I believe copper oxide, or iron oxide would work for this.

resistance thermometers can use semiconductors like graphite, special ceramics or Platinum with it's special property

I saw it in a video, i'll find a link soon, in the context of a simple introduction to resistance temperature probing.  The man heated the tips of the copper wires till they where red hot.  Once cooled they where coated green.  He twisted them together, and had both ends linked up to an ohmmeter.  Then using a cigarette lighter, he clearly demonstrated the relationship between heat and resistance.
