I have not posted much much of my slabbing, trimming, or jewelry projects lately. Been a bit under the weather. I did fill a slab bucket over the last month with about 50 cuts on 12 different rocks, but I have not had the energy to photograph it. I also blocked some boulders of Stone Canyon and Outback Jasper with the angle grinder since I posted my initial blocking session with the angle grinder, but I did not take pics this time.

I did get these slabs on ebay last month, along with some rough of the same material, so I thought I would post a pic. I am not sure if the white bits are as hard as the rest, or how good a polish it will take. I hope to find out soon. I did mark out a few shapes. I kind of like how the material offers large simple shapes of different color from which to compose the cab.



The material is a little more opaque and grainey than other stuff I have seen sold as Burro Creek Pastelite, but it does match this pic I saw on DirtyRockhounds: http://dirtyrockhounds.proboards.com/index.cgi?board=Finds&action=display&thread=5858

I am also close to finishing a few settings - (one in copper, one copper & brass, and several in silver), so I hope to post several finished pieces soon. Not sure how soon I will try to set some of this pastelite however. Hopefully this fall.

I have not worked with any of that material but I have collected some in the past.  I read in the Rockhounding Arizona book that a  glassy polish is a matter of careful sanding followed by buffing on leather or canvas slopped with tin or cerium oxide.  Hope that helps you.  I'm  not an experienced lapidary but that's what I've read and it seems like it would make sense.
Also glad you are feeling better.

It's a subtle pattern, but bold enough to show up across a room. I can see how copper would set it off. Pretty material!

Would like to see what you do with one of those, Daniel.  I also agree that copper will be a good choice.

@drocknut: thanks for the tip. I have been working almost exclusively with AO powder on felt, or with 100K diamond belts. I just got the 1st endplate for my arbor, and I need to expand my polish methods. This may be a good test.

----

As to setting, I think I was misleading. I guess my post rambled a bit. I have not thought about what metal to use in any of these settings, or whether to go for a more bare look. I am working on several metal-work projects, some copper, and was just saying I hoped to show those before too soon - sort of as a counter balance to one more posting of rough. The largest copper piece uses a polished ammonite half, and the 2nd largest is a mix of copper and brass with a mottled green stone.

Because of some of the greenish and white-green tones in the rock, copper might work. But I think silver with patina would work well too, as well as a more bare pendant.
