Hi Kreigh, Thanks for helping out. The differential reflectometers turned up in the Google search were for electronic, not optical, applications.

Selby has an article on page 525 of Amateur Telescope Making Book Three (by Scientific American) on doing refractometry of simple lenses with an optical bench. Book Two has a writeup on Refractive Index starting on page 220 that gives a good understanding and suggests several solutions. And if you go to google.com and search on 'how to build a differential reflectometer" you can find several possibilities. Have fun!

The larger nodules when cleaned up look pretty nice in any collection, fossils or minerals. The digging is easy, although messy. All you need is a hammer, pry bar and chisel or reasonable facsimiles.

We'll be spending 8 days in and around Fairbanks, Alaska in August. Does anyone know of sites near there - 1 day trip, maybe - for collecting? I am primarily a cabber and a faceter but I collect some minerals, too. I've collected local fossils only.
