Early cast iron single spout skillet. No heat ring which means this skillet DOES NOT sit flat. Its a spinner and wobbler. Has about 1/8 wobble on our glass top stove. Best suited for coil electric or gas stoves. Cleaned via electrolysis and seasoned with my own blend of natural Pennsylvania beeswax, crisco and olive oil. Wiped with a thin coat of food grade mineral oil to protect it from surface rust.
