Just wanted to see if anyone has tried Bondic adhesive in their lapidary work. Created by a dentist and cures fast with a UV light.
Found several YouTube videos on it, here's a short clip. You could probably do some of your own dental work with this stuff. RickB

knave - I've only stabilized porous copper minerals and some fossils. Have used the 330 epoxy formula below which is posted here on the board. I have friends that have used Opticon stabilizer and like it. I'm sure many here have used it. STABILIZING POROUS STONES From ROCKHOUND NEWSLETTER Via DIGGIN’S FROM DAKOTA l/82 Gen Buresh, Editor July l982 News Nuggets If you would like to try your luck at stabilizing a porous stone such as turquoise so it can be cut and polished, the Silvery Colorado River Rock Club offers these instructions: Take a jar with a lid; add one pint of acetone. To this, add the complete contents of both the resin and the hardener tubes of epoxy glue, mixing well. Add well-dried stones, cover the jar, and let remain for at least four days. Remove stones and allow a week for them to dry. They should now be stabilized and ready for working. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Just mix half an ounce of each part of 330 epoxy in a pint of acetone. (Be absolutely certain everything is well mixed.) Put your rocks and the 330/acetone mix in a jar. Make sure the 330/acetone covers the stones completely. Seal and leave for 2 weeks. Open and let the acetone evaporate. It might not be fast yet it is very, very effective and none of the ingredients have a shelf life, you don't have to worry about the moisture content of the stones and it's inexpensive.

Put the rocks in dry, lazer will grind and polish the batch very quickly. Imagine this: program a machine for a cab (size, shape, type material you are using) hit the cut and polish button. Come back from lunch and your cab is all ready and polished. All you would have to do is drill, epoxy and put the bail on your heart. |

Technology would give you more time to find the rocks in the wild. You can cut square preforms for all cabs if you'd like to.

I had some adhesive like this. It was really thick and fairly expensive. I bought it at Menards. It did not work well for gluing on dop sticks, I don't think it could handle the sideways pressure. But to be fair I only caulked it around the stick. No way to get the UV light under the stick. Because of how thick it is I don't think it would be a good candidate for stabilizing rough either. May possibly work for filling cracks, but at $10 for a tube about the size of a normal super glue tube I believe there's better, more cost efficient (and proven) solutions.
