Temp. of film developer

When I first began developing my own films, (in the 1960's), I found that the beakers measuring devices sold in camera stores were not tempered and would break when put over burners on a stove. (I developed color slide, also, and had to get the chemicals' temperatures to 100 degrees +/- 1/2 a degree) I began buying Pyres 32 oz. measuring cups and found that I could take them from the burner on a stove and put them in a refrigerator without worrying about them breaking. Now, when I have developer that is over 75 degress, I put it in a Pyrex measuring cup, (along with my stop bath, fixer, orbit bath and photo flow, and put them in the refrigerator with a thermometer in each, and monitor the temperatures until they reach that which I will use for the day. Normally about 72 to 75 degrees. I have never developed at more than 76 degrees, but believe it should be possible. Why not keep a used refrigerator and Pyrex measuring cups in your garage, and try this. Hope this helps. David Huffman
