:Thank you for commenting that. It would be valuable information to have the scale. The volunteers who have uploaded the images may not have been aware of this question, or may not have known the scale. However, I think that even without it the pictures offer a lot.

::Well if they did not know to include such basic information they should not have uploaded them. This is a reflection of a fundamental weakness with Wikipedia: contributors do not need to have any understanding on the subjects to which they contribute. |

:Size information has now been added to some mineral articles, and instruction pages have been improved so that future picture uploaders would know. Best regards [[User:Rhanyeia|<font color="#008899">Rhanyeia</font>]] 10:29, 21 August 2007 (UTC) |

Hematite also has magnetic properties. — Preceding unsigned comment added by 67.99.0.214 (talk • contribs)
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]
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...

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 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]
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]
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. — Preceding unsigned comment added by 81.153.64.39 (talk • contribs)
