If you are referring to the shiny marks on the rocks, those are not scratches. Looks like you are using a metal colander/sieve and it is leaving marks on your rocks.
They will go away during the next tumbling round. Just be sure to not use a metal colander/sieve after the polish stage.

Agree with others about the "scratches". Your game tiles in the second pick look really good.

I'm not sure what filler you use for polish stage, but the .20 g airsoft pellets at a 50/50 ratio works great for my rotory obsidian polishing (the pellets don't float like the other plastic beads you find out there). Tried to polish in UV 10 a few times but had much less bruising and great shine from rotary. Stage 1 ROTARY, UV stage with ceramic 2 and 3 and back to rotary for polish using rock shed ao. polish and airsoft bb's. Working great for me. Hope this helps.

I suppose not, or the obsidian is softer than most? The screen came from The Rock Shed so that's a bit surprising. Either way, thank you for the easy solution! |

I agree with the metal colander theory. It took me awhile to figure out I was leaving marks on my rocks with the brass hose nozzle I was using to wash them with. I don't use metal anything anymore except a pick to remove ceramic media from "tight places" in tumbled rock.

Question, are they scratches or are they marks. If they marks I would not worry about them, they will go away. Most rocks are harder than metal. I have been using a metallic wire colander to wash my rocks out for years and have never seen a scratch Including twice after polish, the polish run and the after polish soap run with no marks. Is this the first time using the colander? if so maybe it's a coating of some sort on the colander that is coming off and will eventually be worn off. I believe jamesp polishes his glass pieces in a metal hopper he built and they come out great. Henry |

Henry Just went out into the garage and tested a piece of polished Brazilian Agate with a dental pick, I could not scratch the agate no matter how hard I applied the pick to the surface of the rock. That is different that applying the pick at great force into the rock, it could be chipped but that is a result of the force applied. That's how rock chisels work on rock outcrops, a tip of the chisel applied with great force will damage and eventually crack a rock. |

The metal colander is not scratching the obsidian, just leaving streaks; sort of like a pencil. |
