...In straight obsidian I think the gravel and ceramic mix prevents a class is water wet Loto shine on the obsidian. My aquarium gravel is the brownish mix of colors from Walmart. It has now rounded out and is very hard, it has a awesome shine! I still use it in my mixed loads of agate, jasper etc. Hi Orrum - for the heck of it, try this test - scrape the tip of your thumbnail along a beautifully rounded and polished piece of quartz or agate. Then try it on both the ceramic media and perhaps the aquarium gravel you use. I also have some brown gravel that takes a lovely polish, but doesn't pass the fingernail test. I use it to polish other 7-mohs stuff, and it does fine, but I don't use it on obsidian. Obsidian gets only the smoothest-finished agate/quartz media. My thumbnail is the arbiter. It can feel the comparative roughness of the more opaque gravels and the ceramic media. I'll be curious if you get a chance and are willing to give this a try. Cheers! Inga
