Re: ferric oxalate
Thanks Brian. So that's it-- nothing else added? I was heating the water, but maybe it should be hotter.
I do like the Chubby Checker idea, though-- I'll try that and-- you know-- dance like I did last summer.
Thanks, Neal. I've never even owned a microwave oven-- but I have done the faux double-boiler with the pyrex measuring cup--placing it into a pot with boiling water. That should work, too.

I have a piece of paper taped up in my work area and I believe it says: 13 gm Ferric Oxalate 50 ml Distilled Water I use the Na2 Palladium method. So a pure Ferric Oxalate sensitizer. The trick is in dissolving that stuff! I heat the water up in a microwave probably around 150 deg F (short of boiling) and pour into the mixing bottle. I keep a pyrex cup with boiling water to reheat that bottle... And shake it for up to two hours. Arentz relates you should stick the bottle in your back pocket and put on Chubby Checkers or something... This got to be so annoying I bought a magnetic stirrer just to make this solution and it is fail safe to get this solution done. I put the powder and heated water in a bottle, with the magnetic stirrer. I put that in a beaker of hot water and the whole thing goes on the magnetic stirrer. And hit the on switch... ???
