Len,
The Corian bowl is 1 1/2 tall on the outside dimension. There are 3 1/2 inch thick layers that were used to make the bowl. If you hand wash it no problem. . . .not sure about the dishwasher though. Not sure how the CA glue would hold up to the temps in the dishwasher The bowl rings no problem . . .they make counter tops for the stuff. The water gets so much hotter and so does the dry cycle so I would hand wash the bowl.
