Hello,
I am a chef out here in Arizona and I fell in love with some rocks I found on a hike. I have been really starting to collect them of all shapes and sizes, but they are all mainly flat or sheet like and absolutely gorgeous. I want to get them to be a nice color that is food safe to eat off of. Is there just a polish that can go on similar to a gloss coat for stained wood? Anything and everything helps!

More information would be helpful . . .
Pictures of what you already have would be best Some idea of what you want to end up with would be awesome Size, Shape, Weight
Rock polishing does not normally involve adding a coating to the surface of the stone although you can do it as a shortcut Usually the surface of the stone is worked with smaller and smaller abrasives until it is shiny
The simplest easiest thing I can think of is a Polished Slab, possibly rounded down in the center

Also, be careful what types of rocks are used. Some contain materials that are not food safe, even after a polish. Agree, that coating the rocks with something is not an option. I have seen some beautiful plates and bowls created by glass artists who embedded thin, smoothed rocks within glass.

You won't want to coat them, you'll want to grind and polish them. You can do this with a rotary or vibratory lap, or a hand-held grinder, much like an angle grinder, except with a water supply and diamond pads. Best to start with a nice flat surface, like that left by a slab saw.
Vast quantities of softer stones are being cut into plates in various countries, from Moroccan fossil rock to Mexican alabaster and British bluestone.
Low speed lathes do the job as well.
Experiment, and have fun!

Hey there chefdeever! Any pictures of the rocks you wish to turn into plates? I would really like to see them ☺
