Huge vintage Pacific pottery bowl, smooth art deco shape canary yellow

Huge (12 1/2" in diameter!) vintage Pacific pottery bowl, solid canary yellow glaze, smooth art deco shape.

It's about 2" tall, a shallow serving bowl for salad or spaghetti suppers, or simply made as a decorative piece?

It's in very good condition with minimal finish wear or scratching to the glaze, no chips, hairlines or cracks.
