- Support As always. Why no centimeter cube this time? Greg L (talk) 02:54, 17 July 2010 (UTC)
- Judging by the break on that bar I assume because this metal is very brittle and probably not really able to make a cube out of it. — raeky (talk | edits) 02:55, 17 July 2010 (UTC)
- I suspect we’re looking at a boule. If that’s the case, the fact that it is a single crystal may explain what appears to be a brittle-looking fracture—indeed, single-crystals don’t have jack for ductility. Platinum-group metals are generally notable for being exceedingly hard. And, indeed, hard metals aren’t exactly a joy to machine. But I should think one could grind one easily enough (assuming one had access to a grinder). Greg L (talk) 03:06, 17 July 2010 (UTC)
- I'm still working for and to have a 1cm3 ruthenium cube. It isn't ready yet. I hope to get one in the near future. --Alchemist-hp (talk) 11:43, 17 July 2010 (UTC)

- Support - nice. -- Jack?! 03:06, 17 July 2010 (UTC)
- Comment: I'm less sure about this one. It's not the lead image; specifically what is this adding to the article? I'm not doubting that it adds to the article, I'm just curious. J Milburn (talk) 09:57, 17 July 2010 (UTC)
- The image shows the second step of a metal processing and the brittleness of this material. The first step is: metal powder production. --Alchemist-hp (talk) 11:43, 17 July 2010 (UTC)
- Question. What's the white colouration on top? Looks like the reflection of a fluorescent tube perhaps, but I couldn't really say. I'm not too sure about this one either (given the regularity of these contributions I'm guessing Alchemist-hp has pretty free access to these samples, so a reshoot is easily possible?). --jjron (talk) 10:50, 17 July 2010 (UTC)
- It is simply a reflection of the sky. This ruthenium sample is a mirror. You can only see what the metal reflects. --Alchemist-hp (talk) 11:43, 17 July 2010 (UTC)
