Anne - sorry to be dim, what is SU please?? - I guess there is some reason why this deep green has been uncommon as a colour - it is, I think, very attractive.
Christine - I should have made it clear that in fact there is a flat ground outer rim to the base - although not clear in the second picture. It is not very wide, but certainly is there. Your ideas of the nature of a possible base sound interesting - and with this degree of wear on the underside recess, would seem that there may well be more age to the bowl that might at first be thought.
