Reticulation

I like to get all my chemicals the same temperature, but at what temperature difference should I start worrying about reticulation? Sometimes getting all the washing water a similar temperature can be a chore and I've seen some videos where the photographer doesn't seem to care about the temperature of the wash water.

If you can use the Ilford method of film washing

you don't need much water at all so it's usually very easy to fill a jug with enough water at a controlled temperature, and it's good enough method to call it archival. Essentially you only need three times the volume of water as you used for your fixer to completely wash the film.

Yes, this is the method I use. What temp difference between jugs should I start being worried.

Edit. I see on the link above it suggests +/- 5C

Reticulation is a concern which is a little bit out of date, you have to climb from 20°C to at least 26°C to attain that risk. It used to be less in the old days.

I think you could stretch it to more than +/- 5C, just don't plunge it into ice cold or hot water. The emulsion is pretty tough, it's big swings in temperature that cause reticulation.

Thanks to both of you.

At over 10 degrees ºC.

All my chemistry is at the same temperature, but when it comes to washing the film, I lower the tank/film  temperature in three stages with jugs of water before using a Paterson hose connected to the cold tap.  I’ve never had a problem with reticulation

Me too, usually reduce the wash temp gradually, figuring it is the thermal shock that articulates.

I haven’t seen reticulation since the days of home processed Ferrannia colour slides in the 1970’s.

It is very difficult to get reticulation with modern emulsions and coating processes, like forgetting which is the hot tap and which is the cold tap. But temperature like any other aspect of processing isn't important because it's being overly careful, or that getting something on the film depends on exact timing, but that diagnosing a failure relies on a repeatable regime to track where the failure may be and sort it out.
