About this item Impact-bonded aluminum bases provide fast, even heating. Safe for the stove, oven, broiler, and dishwasher. Long, ergonomic handles provide a secure grip even with full, heavy pans, stay cool even when pan is hot, and are double-riveted by hand. Fill lines make measuring easy, and covers have straining holes that line up with pour spouts to drain liquids without having to use a separate colander.
