I love the way pieces look unglazed.  I made the wall hanging face planter for myself.  I ultimately decided to "glaze" this piece with just oxides.  Rutile and a bit of Red Iron Oxide and some chrome. It really retains the personality of the piece without glossing over any detail.  Oxides are great on sculptural and non functional works.  I currently have a piece in the Richmond Art Center's annual memebers exhibit with oxide decoration called "Incognito".  It's the cigar smoking bird on the high fire ceramics page.  If you get a chance, go check it out along with lots of other great stuff.  The show runs June 16-August 17th.  The artist's reception is June 30th from 2-4 pm
