Purple Feldspar and Actinolite sphere
« on: June 26, 2016, 01:09:16 PM »

Jhon this is the material I will try and pick up for you.  It is really solid and the Feldspar takes a great polish.  Obviously the Actinolite masses tend to have a polish but not high and more diffused.  The Howlite I can collect out here also works up real nice in a sphere.  I cut one and it looks like oriental pen work since I cut down till the veins almost disappeared, never saw it when starting the sphere but lucky it was there.

Chris was going to bring the crystal by today but haven't heard from him yet. I will show him the pictures.  Are you making spheres too?

Both are very interesting but that is probably the best use howlite has ever been put to, beautiful piece.

Not really doing any.  I purchased the motors and put together a frame etc to make a sphere machine based off an old friends sphere machine that they used to produce before they passed away.  Never got around to putting it together.  I have had the bug to lately, but I have so many other projects it is on back burner.  I did hand cut 2 small spheres by hand - roughing them out and then using pipe caps by hand with grit to finish them.  By hand of course I chose soft materials and did a cave onyx and howlite.  The ones I did 20 years ago were:
Icicle Agate, Blue Forest Wood, Flowering Onyx, Palm Root, Nipomo Marcasite, Nipomo Sagenite, Sierra Pelona Onyx, Silver Sheen Obsidian are the ones I remember and the 2 shown here, most were 2 to 2.5.

I do have an area with large chunks of Ilmenite that is very unusal material when cut.  The Dark and chrome looking areas remind me of the Widman / Statman lines of Meteorites.  On top of that it has high gold content.  I had some assayed and I'll have to find the assay report but It was either .4 or 4 ounces per ton.  Of course being in Iron the recovery would be a nightmare.  I made some cabs out of it and think it would make a cool sphere.  I found out about the Gold because I had a guy in our shop take a torch to it to see what happened when it melted I was thinking forging but had no idea about forging.  Anyway he took and blasted a huge cavity in the Iron and in the bottom pooled the gold which I first blew off as Pyrite and then remembered that Pyrite doesn't melt and had a different piece assayed.
