Measurements: 3" X 3-1/2" Handmade by Chet Salustri. This small tumbler was thrown and then hand painted.The glazing process involves applying underglaze color with a spray gun along with some brush work. After the work is fired in a kiln, he covers the piece with glaze and fires again to give a glassy finish. The final step is the application of china glaze for some of the small details. Dishwasher safe.
