Jack,
Back in my younger days when I was into rockhounding in a serious way, the procedure for creating a "button" was to first char the wood so the sample would rest on charcoal before you tried to reduce it.
Then you reduce it with a neutral flame. After you have a button you can test it in several ways... a scratch test on a clean abrasive surface such as the back if a 4"x4" tile. Trying to see if it is malleable or glassy in nature by hitting it with a hammer... etc.

Somewhere around here I have a great field manual, I believe the name is something like " A Field Guide to Rocks and Minerals" and the authors last name was Pough. It has an extensive section that goes into greater detail. The book was reasonably priced and widely available. I also have another field guide put out by the Smitsonian.
I also have field collection guides on a number of things: Mushrooms of North America, Fossils, Flora and Fauna... I'm a bit of a collecting nut... mostly information and I like to be outdoors.

Chuck

Hi Jack,
In Arkansas there are areas where black coatings and fillings in rock fractures are manganese oxides. Red is common to be iron, but iron usually only stains a rock. If you send me some of the rock pebbles, I will look at them and if required make a few tests to identify your mineral. Are they from the area where the bauxite deposits were mined. They could be lateritic iron or aluminum coatings. mike
