Un-Marked Sponge Wear Nesting Bowls (4) Pink & Light Tan

Description

I am not sure if this is Sponge Ware or Spatter Ware-- (Hopefully someone out there will let me know)
Color-- I would call a deep pink and light tan.
Measures.
#1-6 3/4
#2-5 3/4
#3-4 3/4
#4-3 3/4
(I do not know if they are dishwasher safe.)
(I do not know if they can be put in the oven).
What I can tell you is (2) of the bowls have a small chip in each and one of those also has a hair line crack and discoloration where the crack is---inside but not outside--of 3/4 inch long inside.
Some light wear from age.
Also I can tell you these bowls graced our table for many years on Holidays from the late 1930's.  These are from my family estate.
My pictures may not be the best so ask if you need more.
