Temp for Mixing Chemistry

[psmith]

Hi I'm about to try my hand at mixing up a batch of developer and I have a proper scales, ingredients, and weights needed. My question is at what temperature should I mix the chemistry? Room temperature? I've used Kodak powder developers for many years and they must be mixed at 125 F. What about the raw ingredients I got from a place like Photographer's Formulary to whip up Thornton's two step developer? Any help appreciated. Phil

The recipe you have for the developer should tell you that. It depends on what formula you're mixing. Some will mix at room temp, some need very hot water.

Normally, for dissolving pre-packaged developers, just a little to hot to dip your hand into comfortably. For 'home brews' this should speed matters but room temperature is normally OK too.

Cheers,
