I'm eager to try Gerald Perry's ppm meter so I can have a way to measure ppm on *lots* of samples. A FOAF has access to a scanning visible/UV spectrophotometer, which I think will give us lots of insights into the properties of our preparations. And we've got Jim Einert on the way to owning his own dark field microscope. If somebody on the list has an extra 35mm camera body, or we can take up a collection, he can even be equipped for photography. Won't *that* spruce up the web pages!! What I'm saying is, we've got the makings of a decent research and development team here. Every person on the list can contribute to and benefit from what we, as a group, will be learning. The expenses would be minimal and fairly well distributed. > Something I`ve noticed missing from most procedures given is > electrical data. ... Get a multimeter ...

But until I have a way to measure ppm and particle size on a *lot* of samples cheaply, I won't know just how sensitive the results are to all those variables. I'll post the procedure I used to make these batches. But you'll all see that it is more complicated than most people will be interested in duplicating. I'd still like to have a simpler recipe that was reliably calibrated as well. I'll be working on that soon, I hope.
