Abstract: This invention is comprised of geometric features that are added to the bottom side of a common ceramic coffee cup or mug, and can be used on any drinking vessel. It is designed to allow the vessel to dry completely during the typical wash and dry cycle of a common dishwasher. The current art has a concave bottom which retains water and debris even after the wash and dry cycle is over, and then spills that water and debris when it is pulled out of the dishwasher and set right side up. My invention has a convex bottom that does not retain water or debris, and has legs around the bottom edge to hold the vessel upright, not letting the radius of the convex feature at the bottom to touch the flat surface the vessel will sit on when in normal use.
