Talk:Hematite: Difference between revisions

Revision as of 22:13, 15 August 2007

What is the difference between hematite and rust? — Preceding unsigned comment added by Archuro (talk • contribs)

Nothing really. Hematite the pretty mineral is more massive and crystalline. The crystals can form when the mineral is precipitated from liquid. When it forms chemically on iron, that's when you get the red, powdery version. No large crystals form there (only tiny ones). --DanielCD 18:13, 16 March 2006 (UTC)[reply]

So hematite can't rust? An acquaintance of mine was interested in using some as part of an outdoor sculpture, but was concerned about rust.

I thought most rust was actually various hydroxides of iron, for instance Goethite. See Wikipedia article on "rust".

Also... I've always told my students that the "Hema" in Hematite meant "blood" in Greek, but I actually went and looked it up tonight (funny story to tell, later). According to the English-Greek dictionary at:

http://www.kypros.org/cgi-bin/lexicon

blood = αίμα, αφαιμάσσω

        aima, afaimasso 

in both modern and ancient greek. "Hema" or "Heme" didn't come up with anything. It doesn't seem to be latin, either.

Also.. the Wikipedia article for "hemoglobin" says that the name comes from the "Heme group", and does not mention anything to do with ancient Greek for blood.

OK, the funny story. And the reason I looked this up. Was on the train yesterday (in Kuala Lumpur), and standing in front of me were two Indian schoolgirls, in uniforms and name tags. Name tags read "Hema" and "Vino" (probably short for somethings else). I was very amused by the fact that, there, in front of me, stood "Blood" and "Wine". I didn't say anything to them, of course..

So as you can see, this spoils not only a good joke, but a great story I use in those mineralogy lectures...

Ah, what a difference a half hour makes.. I can see now that "aima" = "hema" once you've run it through an interlanguage corruption filter...

Yep. You left out the spiritus asper mark, which makes it haima, not aima, then Latin spells the diphthong ae instead of ai, and then you get the British spelling haem-. The American spelling hem- is a simplification that reflects modern pronunciation. —Keenan Pepper 22:38, 14 July 2006 (UTC)[reply]

It would be nice to see a bit of an addition that describes the jewelry process. I heard that most jewelry out there is manufactured hematite. I've heard the name "hemalyke" but can't confirm what it is. -- Sy / ^(talk) 17:17, 24 May 2006 (UTC)[reply]

Por que? Mi foto no esta includo sor el pagina de hematite? No es si buen por eres sor el pagina? Esta tus empiro? No soy muy contenta con Vsmith! Innovati 02:20, 19 June 2006 (UTC)[reply]

I believe this is the English Wikipedia. Now my high school Spanish was a long time ago, so I'm not sure just what you are saying. It seems to me that a cartoonized posed photo of what appears to be a zonked out pseudo-hippie staring at his finger doesn't really fit here. The dude doesn't look like a hippie to me. I get the feeling that it is a vanity photo (whee, I'm on Wikipedia!). Anyway it seems that a close-up photo of some polished hematite jewelry would be more fitting. Vsmith 03:04, 19 June 2006 (UTC)[reply]

Well well well, it's been a while since I took spanish too, just in case you tried to put it through a translator. Well, not only is that photo *not* of me, but it is also not posed, despite the excellent photography. I have a series of that kiss, and this is but one of the shots.

I hope you will come to enjoy the non-scietific properties of Hematite, the spiritual side of the stone. Perhaps this is not your thing, but that doesn't mean that it shouldn't be included on the article as a reference for those who do care to find out.Innovati

I think that since wikipedia is about information, we shouldn't restrict what may be useful to others because we have little interest in it ourselves. Should we delete pages on things like Hilary Duff, only because we don't like them when they could be informative to others? That doesn't sound like freedom of information to me - unless something is non-factual, I don't see a personal bias as being strong enough to merit deletion. You have to give more of a reason than that, or maybe this isn't the place for you and perhaps you've misunderstood the point. This isn't any one person's web page, everybody is equal and everybody's information should have equal opurtunity. Oh, and use the talk page, not the histroy page in the comments to ask about or justify why something should be changed before removing existing content.Innovati

Removed again, looks like vanity photo - even if it's vanity about your own photo. If it were to be useful here, an image should at least focus on the hematite jewelry rather than what appears to be a pose of a drugged out pseudo-hippie. Vsmith 01:09, 12 August 2006 (UTC)[reply]

Does this line seem a bit inappropriately worded as well as unreferenced to anyone else: "Many hippies today still wear this stone as a regular part of their wardrobe." ??? Pledger166 01:00, 17 January 2007 (UTC)[reply]

What causes the different colors? Why are some forms shiny and some matte red? —Keenan Pepper 22:39, 14 July 2006 (UTC)[reply]

Apparently the magnetic toys, sold under names such as 'oidz', 'uberorbs' and others, are made of hematite, was gonna add a few words about this into the pop culture section but could only find the following reference on play.com and wasnt sure if it counts as a real reference or not (yes im a n00b, no biting plz): http://www.play.com/Gadgets/Gadgets/4-/852389/Oidz/Product.html. I'll add the bit to the article in a few days if no-one objects or offers and advice etc Pledger166 02:39, 16 January 2007 (UTC)[reply]

A sales pitch by a commercial adv site is hardly a valid reference. Hematite is not a metal as the site states, but an iron oxide mineral with limited magnetic properties. Vsmith 01:32, 17 January 2007 (UTC)[reply]

I agree that the reference is rubbish that's why i queried the fact in here first, i wont claim to know too much about hematite, thats how i looked at this page in the first place, however there does seem to be a vast amount of mentions to these toys being made from hematite, simply type hematite and oidz into google and u'll get more than a thousand hits, there also seems to be a fair bit more info suggesting the magnetic proporties of hematite, as previously suggested by some one else at the top of this page, if anyone knows more about this, information would be gladly recieved.

Does anyone know about the song by MC Hammer where he says "Hematite" and then music plays?74.67.228.2 03:33, 17 May 2007 (UTC)[reply]

He's actually saying "Hammer time" and then does the little foot wiggle dance. --Rocksanddirt 15:34, 31 July 2007 (UTC)[reply]

The spelling hematite should be used in all scientific publications. The International Mineralogical Association (IMA) discredited the British spelling, Haematite, in 1980. Mineralogical Magazine vol. 43 (1980) page 1053. Diamonddavej 23:27, 15 March 2007 (UTC)[reply]

• It is the agreed spelling and not the "correct" spelling.
• The British spelling was rejected not discredited.

Please can someone give an idea of size, such as a scale bar. This is very basic stuff. Not including these is bad practice and makes the images of very little value.
