A Ruskin Pottery high-fired vase covered in a speckled mint green glaze over running lavender

A Ruskin Pottery high-fired vase covered in a speckled mint green glaze over running lavender, and white impressed mark, 1907, factory grind to the base rim 21cm. high The Three Flask shape vases all have a similar factory grind to the base rim. Close examination suggests that it has been caused by a failure of the stilts in the kiln and a possible build up or run of glaze.
