This was first batch I burnished in over a year. Ever since the big polish comparison test caused me to switch from alum ox to tin ox, I have been letting the tin ox batches sit around and not go through burnish, just to learn about the tin ox shine. Since I had been sort of planning some burnishing testing, I just decided to burnish this one one day (24hrs). It was very obvious that the shine had improved.
A wider variety of pet wood than normal for me. Most of those are from Oklahoma, a few from Nex Mex, and the rest all over. I'm kind of fond of the almost black pieces.
More Cerro Peternal chalcedony from New Mex.
Misc. mostly jaspers.
Close up of a pretty one. I can't tell sometimes whether a a piece is pet wood or a piece of jasper which wood-like brecciated material inside.
This is a very unusual piece, I think from western Oklahoma.
Pretty sure this was in a purchased batch.
Misc. agates, including a very hard Brazilian agate I had cut up to process.
Unknown but probably chert.
More psilomelance laden material from California desert. That one piece on upper right is one of my prettiest rocks of all time.
Almost 4lb piece of chert from western Oklahoma. Not quite silicified enough to produce great shine.
Chert from western Oklahoma including some closeups of especially pretty pieces. There are some pieces of mostly grey stream chert from OK/AR/MO junction area.
I really like the color is this dark green jasper. It has a name, but I forgot what it is. I bought some. That picture jasper has perhaps the best shine ever for me on that material. Bought. These are 3-4" long.
There are 2 pieces here of Mary Ellen jasper from Minnesota which I purchased. Their surface is almost always imperfect. The one rock that has some dark green in it is one of my favs. I found this somewhere and have never found but one like this. Normally I keep grinding until all fractures are gone, but had to stop on this one or it might be too small and I like it. If anyone knows what this rock might be I would enjoy learning. Look at that unusual distribution of green color in the rock--why is it like that?
Another piece of oolitic chert. This actually came from same rock as a piece I finished and photographed a few weeks ago--from Oklahoma. That bottom piece is nephrite.
