I am heavily leaning towards purchasing around 3lbs of Kingston conglomerate. I am planning on slabbing and cabbing it. Has anyone every worked with it before? Thanks in advance.

Yes, I have cut and tried to cab Kingston in the past. Once it is slabbed, it is prone to crumbling of the preform due to the weak cementing of the conglomerate in it's natural state. The nicest ones I had come out....can't find pictures......I used acetone and 2 part epoxy to "stabilize" the slabs first. 50%/50% Acetone to epoxy. After a week, I removed to lid to allow the Acetone to escape and a week later they were more stable and took a nice polish.

Yeah, we've also cut a little Kingston. Any kind of copper is fun to play with.
As rads said, it can be crumbly, and you have to expect some inconsistencies in the polish on unstabilized pieces.
You can get lucky with some unstabilized pieces. We have, but don't count on it. Any type of rough can vary from piece to piece.
There are other native copper ores that are more solid. Some Michigan, some we saw at a show from Pennsylvania. Usually pretty spendy.

It looks like nice material. Thank you! |

Thank you! I wanted to cut some copper and this looked perfect. I think I'll still try it, just to play around. I might try stabilizing if it doesn't cut well. That's really helpful, thanks! |

I like this material and have a large set of bookends someone made for me in the 1980s. They are polished and coated with a heavy clearcoat because the copper becomes tarnished with time. As with any conglomerate crumbling can be a problem but the clear coat solves that for bookends. I am posting two photos from the net so everyone knows the material we are talking about.   |

I should have posted a picture when I started the thread. I bought 3lbs today so we'll see what shows up. |
