Developer Temp

Perhaps i have already made a mistake, but.....what about the Liquidol itself.?
I have an opened and a new unopened bottle. Can/Should i store those bottles in the refrigerator.?
When it is hot here...like 96-103 outside, it will be 80-85 in the house.
Thank You

It was designed to have a long shelf and tray life. It is not infinite, but is longer than Dektol.

Test before use.

Given how hot some areas of the U.S. can get in summer and mention of the cold tap delivering water at over 90F it has surprised me that I haven't seen more threads on what B&W film and paper developers work at higher temperatures such as 80F plus.

Out of curiosity and as it may help others like the OP, what does work and at what temperatures?

Where I live is one of those places in the USA where tap water does, indeed, reach 90F in late August and early September. But that is "wash water". Developers, Stop, Fixer all can be kept at 20C and when it is time to wash, slowly bring the film, paper up to the tap water temperature and above all "THINK".......Because things do happen in warm/hot water. If necessary wait for winter to do darkroom work. But then that is the only time it is cool enough to go outside and expose film. Oh what to do, what to do?......Regards!

B&H seems to have mixed this up a bit.

This is from B&H site description of Liquidol.

"You'll also find this developer more "forgiving" than other developers in that it tolerates over/under developing well. The flexibility of Liquidol gives it an edge over other developers - especially when using printing paper that incorporates its own developing agent. You'll find it similar to Dektol but with better shadow detail and a shorter developing time of about one minute."

The developer incorporated part ?? Just the opposite of Freestyle and Formulary.

Does anyone still make developer incorporated paper?

Actually, the last I tested it, Ilford MGIV paper contained some developing agent. However, what is said is true, all except for temperature which is not mentioned in that excerpt. Try experimenting with your paper. It may be just fine as temperature effects do vary with emulsion.
