When trying to warm up developer quickest, does it matter if the surrounding water is much hotter than the targeted temperature or just the temperature that I want the developer to get at?
Are you are wondering whether the chemicals will be damaged? In my experience, no. I frequently use a water bath at about 60 or 70 deg C to heat chemicals from mains water temperature (less than 10 deg C in winter) to 22 deg C. I have the chemicals in plastic beakers, which hold very little heat themselves, and the water bath in a plastic washing-up bowl. I do 'watch the thermometer like a hawk' as someone said above, and stir constantly. I also have a water bath at the target temperature ready, and simply lift the beakers across when they reach the target temperature. If I use a stainless steel beaker instead, heating is quicker but it is necessary to make the move well before the target temperature is reached, as the beaker itself holds a lot of heat.
