One of my best selling pieces over the years was the Sea Fan glass lid. Before it became glass, I made each one in porcelain.  It was common to loose about 1/2 of these in the firing, as porcelain can be so temperamental.  When I found Hugh McKay (now retired), he was able to transform my ceramic pieces into glass.  When my glass lidded pieces are all sold, there will be no more created.  
This piece is a nice size, measuring 19" h x 12"w.
Gallery price is $4200
