ABSTRACT:
A tray assembly comprising a bottom tray, a support grid, and a top screen. The bottom tray includes a generally flat bottom wall having an upturned side, the side forming a ledge. The outer contour of the grid is similar to that of the ledge and the ledge supports the outer periphery of the grid, the grid extending across the flat bottom. The top screen comprises a flat screen and a border member around the periphery of the screen, the border member being secured to the screen and removably attached to the upturned side of the bottom tray. When assembled, the top screen is supported by the grid and the grid is supported by the bottom tray, and a piece of greenware to be cleaned is placed on the top screen. Scrapings from the greenware fall through the screen and the grid and into the bottom tray. After the piece has been cleaned and bisque fired, a person may turn the tray upside down and place the piece on what is normally the underside of the bottom tray. In this position, the person may apply a coating to the piece, and a trough or recess around the periphery of the bottom tray retains any excess coating. The bottom tray has static electricity which attracts the dust.
