How to choose buffing wheel and compound type for differing materials

We are working to improve our local silversmithing and lapidary club’s silversmithing program. We are creating a structured plan with supporting materials and guides. One topic well requested is 'How do I make sense of selecting buffing wheels and compounds??"

In putting the guide for buffing/polishing together I found that modifying the Rio Grande tables on their Resources “Buffs and Compounds Selection Guide” (https://www.riogrande.com/article?name=Buff-Compounds-CGl) will work in communicating this better to our newer Members.

I’m sharing it here and also hope Rio may update their guide as well. (I removed stainless steel as there is no use in our group. Let me knw of any errors or omissions.)
