Lanthanum oxide
[edit]Hello, I was wondering if you could upload a new image of lanthanum oxide. In the first version, the colour balance appears to be perfectly fine, whereas it has a substantial greenish-yellowish tint in the later version. Best wishes --Andif1 (talk) 11:55, 10 April 2017 (UTC)
Hello, the colour balance of the new one was obtained after a calibration with a colorchecker passeport (a colour chart), the product was greenish yellowish. I have two bottle in my lab now, one is white, the other slightly greenish. I do not know why, but this what it is. --GeoffreyHautecouverture (talk) 11:23, 23 August 2018 (UTC)
