Abstract: Systems for and methods of drying a wet skin of a wet skinned ceramic ware are disclosed. The wet skinned ceramic ware includes a dry interior web with an outer surface. The wet skin is disposed on the outer surface of the dry interior web. The method includes generating an airstream and then directing the airstream through a first end of the wet-skinned ceramic ware only through an annular portion of the interior web that is adjacent the outer surface of the interior web. The flow of the airstream through the annular portion of the interior web causes moisture in the wet skin to migrate inwardly toward the interior web. The moisture is removed from the annular portion of the interior web when the airstream exits a second end of the ceramic ware, thereby drying the skin from the inside out of the wet-skinned ceramic ware.
