I think my great-aunt had a fascination with unusual and experimental glazes. This iridescent yellow 'tea bowl' is 3 and 1/4 inches in diameter and 1 and 1/4 inches high. It is very fine and delicate, but the glaze is sort of bubbly on the inside of the bowl, almost as if it hadn't 'taken' properly, and this is also particularly noticeable on the base.
The mark looks to me rather like a pair of scissors, and the date is 1914. Any ideas?
