Large vintage hand-formed studio pottery bowl with pooled cracked glaze center, looks like glass. Measures 17 1/2" BY 14" BY 3 3/4" tall at the tallest part. Weighs 9 1/2 lbs! Signed as seen. No damage, does have two small firing cracks at the two overlapped sections. There is a protective clear yellowish goop on the bottom. I removed some of this to show the signature or markings. Any help identifying the artist would be greatly appreciated! thanks, nothing doing.
