There are too many marks on this nicely thrown piece. It reads from top NSP, Terry(or Merry or Berry) Grissette, V.(less than symbol) (check mark) plus something in dark blue glaze? The overall glaze is a rose blushing gray but it has unattractive unbroken bubbles spaced randomely about 1/2" apart. The vase is 5" tall. Because of the quality throwing and interesting glaze, I would like to see more of this potters work.
