Anyone have any nice colored turquoise chalk they want to get rid of? My usual $10 to $15 per pound source dried up.
Thanks!
Phil

I can't, but have a friend who's been in the business for over 30 years who does an excellent job at a fair price. And that's where I would send it to be processed if it was a good enough quality. At his prices per pound (confidential), it doesn't pay me to mess around with epoxy and etc.... Got a couple hundred pounds for me? <G> I can also do a % deal for no cash....

No sorry not a couple hundred pounds but about a pound of Kingman unstabilized that looks solid but if you stick your tongue to it you really get stuck to it. My experience it wont cab even if you back it if its that dry and porous. I am gonna try the epoxy in a quart jar inside a vacumm food bag hooked to my girlfriends machine. I figure the jar will keep tge bag from touching the epoxy and acetone and dissolving. You reckon it will work?

polyethylene is not soluble in acetone.
The impregnation happens when the vacuum is release, sucking the epoxy into the stone. My buddy in Alaska does it three times, vacuum, release, vacuum, release, vacuum, release, lather rinse repeat.

Hi Phil, Not sure if are just looking for turquoise or a mix. I got a line on lots of this stuff, I believe it came from the Blue Bird Mine in Globe,Az. I picked up a milk crate full for $50 to use as yard decor, the board they are on is a 2x12 for reference. Unfortunately the guy is out of town and will not be back until early Dec. Tim Dry  Wet  |

Probably, as long as you're sure the jar can withstand the pressure of the vacuum process. Just leave the resin part in vacuum long enough for any voids/air bubbles to be removed or filled and replaced with the resin and that it really penetrates. Make sure it is dry dry dry. How long depends on how porous. As you're using a process where you can see what's happening, wait for all the bubbles to stop, then let it soak for awhile. My friend lets his "soak" for a couple weeks, but he does hundreds of pounds at a time. Then apply the hardener as a separate procedure. |

Thanks Tim.
That looks more like a chrysocolla/azurite mix, not turquoise. But you're right, it does make for pretty yard rock! Ever slice it up to see what the insides look like?

Do you have the jar sealer attachment for your vacuum?

Thats the plan plus putting the lid and screw ring on with holes punched in the lid.
