Is there a way to get a glossy finish on a bowl that I made in a drop mold then cut off the rim….Cold-worked the cut-off edge but that left a matte finish. Can’t fire-polish because it would ruin the slump. Obviously can’t fire polish before slumping because I need the rim to keep it on the mold. There must be a way to do this but I’m too much of a beginner to know what it is.
More coldworking . With cerium oxide, you can get the surface to a pretty nice finish. It is, however, some work to do by hand.
