Breccia Pipe

The crack is holding so far. I’m shaping it with the diamond burrs in the dremel. The small burrs remove material very slowly. I’m also removing the deeper marks from the heavy diamond grinder.

Here’s what it looks like wet.

Now I mark the bowl and grind it round.

Hogging out the bowl takes quite a while. I’m about halfway now. More to come…
 

True talent unfolding before our eye's !! :coffee2: :icon_thumleft: If it was up to me (my project ) I'd keep on with this and glue to cracked piece back together and use it as a display of what is possible & (for me ) I could learn from my mistakes so I could possibly learn from them. I think this is / could be a beautiful piece no matter ! Thank you for doing and posting this Great project !
 

It’s still in one piece. I’m moving along okay. I couldn’t make the bowl like I usually do because of the crack. It will be more plain. Most of the diamond tool scratches are gone. A few more to go. I’m using a Norton sharpening stone with water to remove the scratches. When they are gone I’ll start the diamond polishing.

This is what it looks like wet. As it starts to take a polish, there isn’t much difference now between wet and dry.

I looked online and tried to ID this rock. I found a tentative match. This is Baraboo quartzite. The white is quartz, the grey is hematite, and the red is plagioclase feldspar. Baraboo, WI is about 325 mi. north of me. My original rock could have been moved by the glacier that far easily.

More polishing to come…
 

I have nearly all the scratches made by the diamond tools removed. I’ll switch to diamond paste next. I put a little olive oil on it to bring out the color. Hopefully it will look like this with no olive oil after the diamond paste.
