I am working on a special project and would appreciate help identifying a glaze (Raku or otherwise) that matches closesly the tones found in the picture below. On the other hand, would it perhaps be easier to find a clay body that when fired matches this tone? From my own view, the piece does not seem to have been glazed. If that is the case, can anyone identify a similar clay body that will achieve these tones? I need the piece to look as though it is centuries old.
