I must admit that I have not seen a bowl/astray like this one before and unable to identify it's origin. The bowl measures 7.5cm in height and 11.5cm X 11.5cm at the top. There is a 4cm concave pontil. Half way up the bowl are visible ripples around the bowl. Not too sure if this is a defect or part of the design. Within the bowl and outside feels to touch, slightly textured. Certainly not a smooth polished finish. Around the top of the bowl that measures approx. 2cm thick. The surface is smooth/polished. Can anyone help identify this? Kind Regards
