Dremel 421 Polishing Compound

Q: can you use this as a final polish on agate?

Thank you for asking your question. Our polishing compound is 400 grit and not something you would use for a finishing compound. We would recommend you get a jewelers rouge with a higher grit to do the final polish on agate.

Q: It is suitable for polishing glass..?

No, Dremel 421 polishing compound will not polish glass.

Q: Can anyone say with authority what the grit size is and what material the grit is? Is it diamond or quartz/sand or something else?

Hello, The compound is 400 grit. It is 76% silicon carbide and 24% vitrified bond. It is not classified hazardous.
