For your consideration is a vase made by Frans Wildenhain. It has all of the characteristics of the Pond Farm style. The glaze is exceptional and changes color based on the lighting.
It's dark and has hints of green. I have a similar glaze on a Marguerite Wildenhain pot and it's cool to see them together. All of my pieces are in unblemished condition (no chips, cracks or repairs) and all of it comes from reputable and documented sources. Thanks for looking and please let me know if you have any questions.
