ginko leaf tray done in Oribe green. recipe is not stable. proved with the vinegar test. tray sold to same person who bought the tree of life rectangular tray. new glaze on bottom tray. different recipe done with the new copper carbonate that is not like the old stuff. much weaker color. lots of re-fires with this glaze. have to get used to pouring it on thickly with my sprayer. have increased amount of copper to 5% since this piece.
