Thanks for the information on the measurements for silver. I would like to have a generator that makes the cs by itself but I can't afford one. I have a great brother who knows how to do all that stuff though so he is going to build the generating part for me.
I know how to make a magnetic stirrer but I need a teflon coated stir bar. These things were all over the place when I was working as a laboratory tech nobody ever gave them a thought, but since I retired I found out just how expensive they are. Anyone know where I can get one at a reasonable price? $90 for 12 is too much since I only need one. Didn't find any on Ebay. Or maybe there is something else I can use for the stir bar......? Linda
