Vintage blue and white swirl graniteware enamel plates and bowls - these are the old ones, heavy, not the new tinny ones made these days!
They're showing age, some discoloration and spots of enamel loss (mostly to the bowls), light scratching. No rust or holes.
They'd make great primitive decor pieces, or rustic tableware for camping etc..
This lot has six plates about 10" in diameter, six plates 8" in diameter - just five of the bowls 6" in diameter x 2 3/4" deep.
