Original – Pure (99.9 %), argon arc remelted hafnium-ingots with visible crystalline structures. View of the front- and backside. Colors are a thin film effect in the oxide layer.

Reason

a nice and high resolution view of remelted hafnium pellets

• Question - Would a pure white background work better? — Crisco 1492 (talk) 11:43, 3 February 2014 (UTC)

  A true white background looks always overexposed for me. This image was taken on a frosted glass plate (milk glass plate?). --Alchemist-hp (talk) 15:16, 3 February 2014 (UTC)

  Fair enough. Though I'd like to see your reply to Hahnchen before !voting, as I agree that the second image is quite nice. — Crisco 1492 (talk) 23:19, 3 February 2014 (UTC)

  Support nice work. — Crisco 1492 (talk) 00:03, 7 February 2014 (UTC)

• Comment - I think something like File:Hafnium ebeam remelted.jpg which also shows the metal unoxidised has a greater encyclopedic value. - hahnchen 22:04, 3 February 2014 (UTC)

  You are right too. But the other image don't show us the main: the crystalline struckture of this material. It is "normal" to see the colorful thin oxide layer at remelted hafnium metal samples. Also at ebeam remelted material, because Hf is a very good Getter material. --Alchemist-hp (talk) 10:43, 4 February 2014 (UTC)
