Higher-than- Recommended Temp for cooking developers

Mani_Reshad · Sep 7, 2024

Hey there everyone!

Mixing developers from scratch usually requires 50-52C temperature and I was wondering what would happen if this requirement was pushed up to 70 or even 100 centigrade degrees. Does it mess with the developer and there’s a limit to how warm you can get the developer to be or is it just the minimum requirement?

Thanks in advance.

You would need to check whether or not the various ingredients start to break down when in water at a certain temperature.
And water boils at 100 degrees, so you may want to avoid generating steam with various chemicals in the water.

Also, it's pointless to raise the temperature above the recommended because everything dissolves perfectly well at the lower temperature.

What I learned from previous discussion here is that an extra 10C is usually not a problem but I've never heard anyone trying mixing at 100C.

Any gain in time from faster dissolution is likely offset by the cooling time before you can top off the solution.
You have to do that because the final volumes are based on room temperature (about 68F/20C) unless explicitly stated.

The only time I have mixed at high temperatures (80C) was getting phenidone and vitamin C into glycol. Everything else is done at room temperature to hand-hot, and mostly at room temperature in practice.
