Ive been cabbing like mad today. Im working on a brazilian agate cab that has plumes in it. While working the stone, I blew through the agate and a chunk of plume fell out. I cleaned it and used epoxy 330 to fill in the hole. Will this work? Ive never had to do this before so I wasnt sure. I dont want to ruin this one.........one side of the slab was typical brazilian. The other side was dark blue and red w/ gold plumes!!!
Thanks!
Shan

Well, it sounds like you've got a beautiful piece of Brazilian agate & you've got to go for it now. Just be really, really careful about grinding and sanding the epoxy. Treat it like you've got a pocket of calcite (very soft and fragile) and you should be OK. If you get done and you're not satisfied you can dissolve the epoxy with acetone and re-fill with a different compound like Hot Stuff or Opticon (depending on the size of the depression). I've had mixed results with all of these, but the "light touch" is important for finishing each. Don't you hate it when that happens!

Hey, Shannon! YOu may have to redo the surface a few time., and sand, and so on. I never use anything lower than 600 because a rough grit will pull out the glue. Mostly I use super glue and a 1200 hard wheel to get the glue down. Also, you may have to repolish the whole thing if the glue polishes up better or worse that the rest. T

I've done that with super glue, it works. Let us know how the epoxy turns out.

I would use the higher viscosity Hot Stuff (yellow) to hold the chunk in place while you shape and sand. At the final polish step, if the glue starts looking funky soak it in a closed jar for awhile in acetone. Then glue the chunk back in place with Hot stuff before polishing.

Shannon, I use 330 for fixing and attaching different stones and found it to work great. One thing I have noticed is 330 will have a tendency to show up when working the stone if there was a large chip healed. Good luck and hope to see post.
