Blue White Striped Stoneware Jug and Bowls early 1900s Mountainside Arts New England Pottery

Blue and white stoneware jug, early 20th century, with three bowls of similar vintage, likely from the Northeast (one is, definitively, being Mountainside Arts Pottery, c. 1930). The jug has a crack in the handle, but it doesn't appear that it ever actually broke, since there's no corresponding break elsewhere to indicate it's been glued. The jug is 12 inches tall, a little less than six across, one gallon I presume. The bowls are about five across, four high, and have a variety of colorful stripes. They're all very heavy; the smaller one may be a mortar (no pestle, though). The jug is more on the yellow ware side of the spectrum than the bowls, as the photos show.
