I found this piece of glacial till breccia at the local river. There are old unused gravel pits in many locations.
I polished the end a bit and saw it had potential. I know the white material is quartz but I’m unsure about the grey and the red. It could be chert.??
I cut some slabs off of it and made several cabs. I have enough material to make lots of cabs. The red material is gem like. Breccia is formed from redeposited material so it could be anything.
I cut a preform to make a small pipe and marked it. I’m making a monitor style and have to remove two blocky pieces after drilling.
Drilling the holes is the most difficult and time consuming part so you do that first. Without two interconnecting you have nothing. This rock is 7 on the mohs scale so all my tools are diamond.
So far so good. More to come…
