As for telling fabricated from cast, often iron casters use sand molds, so the texture of the piece could have a sort of sandy texture; however, it is possible to create a sculpture in cast iron without the sandy texture; by using ceramic shell. More times than not though if it is a large piece it was done using a sand mold which will have the noticable texture. That is to say that the artist left the texture and did not rework the surface after it was cast. Other than that there is other small details that can be looked at, but too many to mention.
