There was some media with the equipment that Dad bought but we have no idea what any of it is. I'm hoping some of you may know by looking at it. These are like a powdery substance. The red one was labeled "red rouge"

The first picture shows walnut shells with red rouge, and plain walnut shells. The second picture is red rouge and some kind of silicon carbide grit. If you open up the lapidary polishing powder and its peachy orange, its probably cerium oxide. If its white it could be tin oxide, aluminum oxide, linde, or any number of things.

Do you know what order they are in, grit wise? Meaning, which one do we use first to tumble with, then second, then... so on and so forth. And the lapidary polishing powder is white.

Welllllll.......
If I were you I'd buy new grit.
Red rouge is for polishing jewelry, so thats out. You could use the mystery silicon carbide, but who knows what grade it is. THe polish will probably polish, but you have to get a surface worth polishing first.
You can easily order a grit pack from the rock shed or elsewhere and save yourself the headache.

If the first bag is triangles or "pyramids" it is a metal finishing media with an abrasive inside. The powdered rouge is used with walnut shell for metal polishing. How fine is the silicon carbide? 60/90 or 80 looks like black sugar. 600 looks like black powdered sugar. 220 in between.

This is great advice (buy new). Purchasing new grit will allow you to 100% know what you're dealing with. For all the time you'll spend tumbling it's the best decision.

Yeah buy fresh.. Using something that you aren't sure about when you are first starting out might mess you up and slow your process. Later when you have your new, are more familiar with the grits etc. you will know what you have and can use it then. Great analogy fromJohnsgems. Never have compared grits nd polishes to sugars but makes great sense. Good luck, Cliff

I weigh the stuff for resale. 400 and 600 a lot like flour really. Blows everywhere.
