You might be on to something...brush handle that looks exactly like a dried up turd nugget.Have you ever considered the labor and time involved with polishing a turd? You'd have to wait for it to dry out, obviously. Then I'm thinking that impregnating it with resin would be good, as it would stabilize it and allow a polish to be given. From there I guess you could go in different directions. Depending on style desired, I guess one method would probably be to turn it in a lathe, then apply a good coat of wax to provide sheen and moisture resistance.
Of course, you'll have your artisan turd polishers, and that's a whole other field.
There's probably a forum somewhere.
