Ashkelon Excavations in the eastern Mediterranean is the site of Phoenician shipwrecks named Tanit and Elissa. Amphorae from there were lifted by archaeologists and tested--mud inside them was tested and the 8th century B.C. ships had carried wine.
Top third exterior is the sediment glaze -- as it came to me, a bit crunchy with who knows what remains had settled there. This one has drips where mudglaze was applied more heavily and shows more variety when you look close into the rivulets. Interior celadon and exterior greenish matte are glazes assembled from refined materials. Light aqua seaglass in thumbwell.
