Small Slab Menorah With Snakes and Eyes

This is a small (6.5 inches long, 5 inches tall) slab menorah with a pattern of snakes and eyes on it.  I couldn't get the measurements of the slabs to come out right and ended up forcing them together instead of carefully fitting them, so it's a little irregular.  It's colored with copper carbonate, which comes out green when applied lightly and a dull metallic gray when applied more heavily, with an off-white glaze on top of it.
