Finished with a clear lacquer and an inset brass dome on top. Comes with a fixing screw and washer, requires hole size of about 1/4" (6mm) diameter through your ceramic bell. The screw has a chain which may be shortened to hold a clapper (not supplied). The most effective clapper is a ceramic bead 1/2" (12mm) in diameter, made from the same clay as your bell.
