Technically these are what Fire King called "splash proof" bowls. Fire King produced a whole line of kitchenware in their Tulip pattern. Shown are the complete set of 4 nesting bowls, the grease jar and the range shakers.
The colors, like the Pyrex mixing bowl sets from the 1940s and 50s, were fired on and are incompatible with dishwashers.
While we would love to have a warehouse full of complete sets of Fire King Tulip, we typically sell individual pieces in our antique mall spaces and at antique shows.
