Help Identify Collection of Small Pitchers (photo)

These small pitchers are part of a collection formed in the mid-1940s to mid-1950s and given to me around 1958-59. They have no marks on the bottom. Can you help? Thanks.

Blue and white: Partly rough, partly smooth surface. Very rough surface around the upper part of the round base. Tiny pottery shards or pebbles inlaid around the edge of the base.

White and peach: Shiny glaze
