I make oatmeal for us right in the bowl in the microwave. Don't have to first use a pot to boil water to then add oatmeal to cook. Just add cold water to the dry old-fashioned oats in the Winter Frost White 12-oz bowl and in 1-2 minutes (depending on how many bowls are cooking) instant hot oatmeal in the microwave. My microwave turntable can hold 3 of these bowls at one time. (Don't cover the bowls when cooking oatmeal or it might bubble out of the bowls.) For portion control we don't use this size for ice cream, but for granola or cold cereal this is a great size. Good portion size for holding grapes or cutup fruits. As for our dishwasher, this bowl fits all over - top or bottom shelf.
