[edit] Photographic chemicals
Hi! Yes, these chemicals are used in black&white photography (hydrochloric acid is used in toners and intensifiers; sodium sulfate is used in tropical developers). Regards, Dorgan (talk) 19:18, 25 February 2009 (UTC)
[edit] Article assessment
You may not have notice the section on article assessment at WT:CHEM, but it looks as if we are going to have to have an assessment drive at both WP:CHM and WP:CHEM. I'd be grateful for any comments you might have. Met vriendlijken groeten Physchim62 (talk) 11:35, 28 February 2009 (UTC)
[edit] PD review
See commons:Commons:Administrators'_noticeboard#PD_review. Thought you'd be interested since you do so much image work. — Rlevse • Talk • 01:35, 25 March 2009 (UTC)
[edit] Talk:Carbodiimide
Hi Wim
Ordinarily I would not tag compound class-articles with {{Chemicals}}, but I do believe this article deserves both {{Chemistry}} and {{Chemicals}} because it does contain a monograph on a handful of representative members. That is not an ideal situation, but that can be fixed in future. What do you think? --Rifleman 82 (talk) 01:25, 22 April 2009 (UTC)
Split off, so it should stay as it is now. :) --Rifleman 82 (talk) 02:09, 22 April 2009 (UTC)
[edit] Oil shale extraction
Hi, Wim. I am planning to renominate the Oil shale extraction article for FAC. Of course, this article is not ready for renomination yet, but I am planning to concentrate on this in coming months. One problem you mentioned is the length of this article. I have done some trimming, but it still needs some work to be done. You have done an excellent work on improving this article and I hope you will have a time to assist to bring this article to the FA level. Thank you in advance. Beagel (talk) 10:47, 23 May 2009 (UTC)
[edit] Sodium sulfate
Hello Wim, I understand your undo, but my aim was to create a "See also" section which is still lacking for the page on "Sodium Sulfate" and it is also a good place to directly link to the first discoverer of the substance, even if, I agree it induces some redundancy. Shinkolobwe (talk) 22:48, 28 May 2009 (UTC)
- Hi Shinkolowbe, a See-also section is only worthwhile if there are additional topics, not covered in the article. Typically, the first discoverer of a chemical compound would be well described in the "History" section, where for sodium sulfate it is. So, adding that to the See also section remains not useful. If you have a good topic for it, feel free to add a new section for it. Wim van Dorst (talk) 21:22, 30 May 2009 (UTC).
