I had saved some chips of glass and rock for something, (probably sacraficials for tumbling) and thought I would try this. Seems to be grinding pretty good so far but has some voids in it. I think I can fix that with some 330 epoxy. If it finishes good, I want to do a little customizing with more of them.  finished pic  It was an interesting little experiment. Seems the more I ground on it the more it changed. I could not get the voids out of it. They're probably all thru it. I'd get one gone and another would show up so, this one is done. So, off to the shop to work another rock - in myrockshop? :help: |

How did you form it?

Toad, I used my scroll saw to make the templete from 3/8" wood, and lined it with plastic. Is that what you were asking?
I'll probably make this one into a keychain thingy

Yep. Wondering how you made the thingy. And how did you stick it all together...

Got everything in the mold and packed together. Then mixed up my epoxy and over filled it because the epoxy settles down

thats cool looking!
I've done the same kinda thing using opal chips and aluminum bottle caps as the mold with 330 epoxy or the resin mix that you get at Home Depot for table tops. The table top resin gets less bubbles and I have a old massager that I use to vibrate the bubbles out.
When its all cured I cut and peel the bottle cap from the resin/opal blank then shape and cab it.
I don't have anymore on hand or I'd post pictures of it

Interesting experiment Gary. I like how it turned out. I have a container of small pieces dropped from the saw that would work nicely with this method.
Would maybe thinning the epoxy fill the voids better?

Gary, I use resin. It works better than epoxy. BTW, I like your idea.

If you like toxic - acetone thins epoxy. And you can use a heat gun to get the bubbles out - but don't get it too hot.

I was pretty sure it was Acetone that thins epoxy, but wasn't positive. Thanks for verifying, Lee.
