Talk:Photographic fixer

message: Isn't it true that one needs a license to buy and use fixer? It has EPA regulations stating that fixer needs to be disposed in a large barrel container, and removed later by a professional service. LCecere 22:50, 10 August 2007 (UTC)
replies: text: Not certain about license issues (maybe in bulk?), but here is a discussion on photo.net that contains links to other info on the topic of disposal. Girolamo Savonarola 22:56, 10 August 2007 (UTC)

text: Certainly not an issue in the UK where fixer can be bought freely over the counter and may be disposed of via the foul drains provided it is well diluted and only in small quantities. Professional processing laboratories need special trade effluent consents or wil need to arrange disposal by specialist waste contractor. In many countries the Silver content of spent fixer and blix makes the value of spent fixer greater than its original purchase price. Velela 23:41, 10 August 2007 (UTC)

thread_title:  text dump - 'washing' 

message: With reference to the above text - I propose removing the 'Washing' section to its own article. I propose this because it doesn't already exist AFAIK, and because washing is a major but neglected part of photographic processes. But it's irrelevant in an article about fixers. I'll leave it for a week or so - if no-one objects I'll 'be bold' and go ahead with this proposal. Cheers. Baffle gab1978 (talk) 03:30, 14 January 2009 (UTC)
replies: text: Since nobody seems bothered, I'll move it this week when I have the time and inclination. Any last chance objections? Baffle gab1978 (talk) 09:28, 2 August 2009 (UTC)
thread_title:  Propose splitting 'Washing' section 

message: I am removing the claim that "Hypo was apparently first used in photography by the Rev. Joseph Bancroft Reade in 1837" and its cit of a 1953 article. In a 1971 article, available here , R. Derek Wood debunks the 1837 date as due to Reade's faulty recollection and provides substantial evidence that his experiments actually date to 1839. In this instance, tradition coincides with truth: "Hypo" was first successfully used by John Herschel, earlier in 1839. AVarchaeologist (talk) 16:06, 7 May 2015 (UTC)
thread_title:  Reade "first" claim 

message: If one reads the article on photographic developers one finds that iron EDTA is indeed used for bleaching, NOT ferrous (II) EDTA but ferric (III) EDTA which in oxidizing the silver is being reduced to iron (II) EDTA. It is most probable that the fresh "blix" contains iron (III) EDTA (ferric EDTA).  — Preceding unsigned comment added by 150.227.15.253 (talk) 11:25, 19 February 2019 (UTC)
replies: text: In any case, as noted, it is ferric EDTA, and I changed the article. Gah4 (talk) 21:52, 27 July 2019 (UTC)
thread_title:  Bleach fix  

message: The article mentions bleach fix, and its contraction, blix.  Many processes separate the bleach and fix steps.  Also, I believe blix is a trademark of some company. Gah4 (talk) 21:54, 27 July 2019 (UTC)
