Im assuming to fix bruises or damage done by rocks chipping and gouging other rocks is to run them through again starting at the beginning? This would fix it correct? I had a barrel of quart, agates and obsidian running. They were all doing great until the final polish stage in which a few pieces of the quartz and an agate chipped and messed up some of the obsidian. If I ran the messed up pieces through again would it fix them? Thanks for any help!

Depends on how deep the bruises and chips are. Removing them could take a while. Also some bruises and chips can form during any stage. Adequate cushioning is required throughout the tumbling process. The larger the rocks the more chance of them inflicting damage. Obsidian is particularly vulnerable and difficult to tumble mixed with agate and jasper.
Have a load of Quartz Crystals and Apache Tears in Polish now I expect a few of the larger Tears to be damaged even with a good bit of smalls in the batch. Will try and get a picture in a few days when the load is done.

Ashley, I'm no genius when it comes to tumbling...just a lot of reading...and a "little" doing! LOL - However, I have to agree with Henry...I bet there's not enough cushioning in your tumbler to keep the rocks themselves from crashing into each other inflicting the marring.

220 might get rid of the damage to the tears if you do them again, but maybe coarse work better. I always have plenty of media when I do obsidian. It might take much longer but they turn out nice. I'm tumbling some mahogany obsidian in 60/90 with lots of media and it is taking a very long time.

I run my obsidian only by itself or with maybe a couple pieces of feldspar or crystalline quartz.I also run a higher than normal percentage of ceramics with the obsidian. I wouldn’t run them with agates or jaspers. I fix my bruising spots on the flat lap and move them back to 1. Hope this helps.

jasoninsdThank you Jason! I’ve seen your obsidian, I know how you roll with that stuff! I’m glad to have your advise.
