These are very nice examples and rare PA Powder Valley Leigh County PA pottery.
Powder Valley in Lehigh County, Pennsylvania, once served as the home of three generations of redware potters - Charles, Thomas and Isaac, and Russell Stahl and artist Carrie Stahl Schultz. Redware, a specific type of low-fired, porous earthenware, received its name from the distinctive color of the native clays which the potter dug, processed, and turned on the potter’s wheel. Redware was an important Pennsylvania German product, first as a utilitarian ware and later as a decorative art. Powder Valley, named for the early gun powder mills along the Indian Creek, provided three key ingredients to the potting industry: wood to fuel the kiln, distinctive and attractive veins of red clay, and an abundance of markets. The Stahl family operated a pottery off and on for approximately 100 years.
