Question:
Hello! I lived in Owatonna, MN for many years and I inherited two 7 inch, ribbed, blue and brown spongware bowls from my Mom. Yes, she told me they were valuable and to be careful with them!

Each bowl has ‘Red Wing Oven Ware’ in blue on the bottom, and I also see a marking, 7 c (??), stamped into the clay of each bowl on the bottom.

I’d appreciate if you can estimate the date these were made and their value and if known. They seem very similiar but have slightly different coloring,finish, etc. – maybe they were made and fired at different times?

Apprciate you help and this is a great site! Best regards, Monica

Answer: Monica, your sponge-ware cap bowls were produced in the 1920′s & 30′s. Without advertising in the bowls and in perfect condition, they would have a value between $50 & $60 each. Al Kohlman
