I've got a lilac example - was incorrectly described as "monart style" (someone that's not seen monart wares methinks!).
Dimensions are 11 inch diameter, 3 inches high, foot just over 4 inches.
Very pretty as also includes flashes of pink, blue and white. Top of bowl dominated by four evely spaced swirls/whorls. Highly polished prefectly concave where pontil might have been. The wear to the base on mine looks a little TOO uniform. Just an observation!!
Pastel colours are similar to some Caithness items - and I think must have been produced since the 1960's...
