Thanks. Well, as it's very expensive material, probably keep one or two and then sell the rest on ebay. Bumblebee commands top dollar, and the rock I cut these from wasn't cheap by any means. It makes gorgeous cabs! I've got to finish cutting the rock before I decide.

It is a trendy material right now and those slabs are real nice. The last show I was at there was only one seller that had any and it sold out quickly.

The yellow part of Bumble Bee Jasper is a mineral called Orpiment or Arsenic Sulfide. It may be orpiment infused in calcite or another mineral. I would definitely use gloves and respirator or a lot of air movement before playing with it. Definitely dump the water in your cabber after you are done working with it. Our friends a Wikipedia say that Orpiment "has been used as a fly poison and to tip arrows with poison". If you smell garlic while working with it you are smelling arsenic and likely too much. The amount of arsenic you can legally have in drinking water and food is measured in parts per billion. Arsenic is nasty stuff.

And here's a question, after cabbing this stuff what can you do with the water and sludge? Methinks dumping it in the backyard is a bad idea.

I wish I was there when you were getting it for $3.50 a pound!!! I have never seen it in the single digits

Was at a rock show and the guy had the market on it(had a bunch)....Told him I wanted a piece about the size of my fist,just to find out if I liked it or not.. He found a piece and I payed $12.00 for it...I think I cut eight slabs of it... He told me,"You will like it and be back"..LOL I like it,but to me its not worth the high dollar they want for it...(Just my opinion)..

I A person has to watch what they are doing around some rocks,they can get your health in a hurry.....I posted the 10 most deadly rocks on this forum,many months ago... I worked in the oilfield and was around H2S a lot,so I walk softly around any type of chemicals...H2S in layman terms,will kill you on the spot!!! Just beware around your hobby,take the precaution's and enjoy..

I am not a chemist but my guess is that since we are talking about a metal compound this stuff would not biodegrade quickly. Wiki says that arsenic has been used as a fungicide, insecticide and that it is absorbed by leafy vegetation which makes me think it would be around for a while. Yea I would not consider this generic "rock dust" to be added to the garden Fossilman I would be interested in that discussion about the 10 most toxic rocks. I made a similar presentation for my local rock club and jaws hit the floor. The old timer's idea of being safe when working with stone is to not lick the rocks. Lets face it, how many of us know the general chemistry of the material we are working, much less the chemistry of the specific stone in our hand. Most of us know that the red stuff in jasper is most likely an iron mineral, but what is the rest? I have no clue and I am a bit of a science geek who does environmental work. Maybe that would be a good discussion to have in another string.

Yeah, fixed the motor (common wire pulled loose from it's lug and was shorted with the ground. Which in a residential house is electrically connected with the common wire anyway. It was too tight and when the saw moved, it pulled itself loose). Then I finished cutting that rock and a few others today, pulled the oil and have it filtering now. Should be ready to reuse tomorrow sometime. Probably won't get rid of all the residual arsenic in there, but will at least get rid of the sludge to prevent it from intensifying. Smelled no garlic or anything any more unusual than normal. Did notice a burnt or acrid smell when cutting the Morgan Hill Poppy jasper tho... The grey-green-tan dirty oil is filtering to a nice normal used oil tint, so not really worried too much. Sludge will go to the landfill, they use a lined pit so it'll be good. Don't think there's that much hazardous volume from one rock to really worry about tho.... The last 10 or so slabs were good right down to the butt, which IMHO, is the best looking of the lot. The poppy jasper coloring sequence is interesting. Will post pics after I finish washing them and get time to photo them.

Orpiment is #2 on that list, also the lengthiest item in Voynick’s article. Good info, good read.
