Sculpture Terminology for BJDs






I don't know how, or when it got started, but I see some people in the BJD community referring to a sculpt as a mold. Or, they refer to a casting as a mold. I am guessing that it all has to do with poor language translations from Japanese, Korean, and Chinese BJD makers, to English speaking BJD collectors?

A sculpt is a positive three dimensional form, originally modeled by the artist.
A mold is a negative of that three dimensional original form.
A casting is a positive three dimensional form that is removed from a mold.

A mold is made around a sculpt. When the sculpt is removed from the mold, an exact negative three dimensional shape of the sculpt is inside the mold.

A mold is used to reproduce the original sculpt as a casting.

When you buy a resin or porcelain BJD, you are buying a casting, that was removed from a mold, that was made from the original sculpt. If you buy an OOAK BJD, made from air-dry clay, polymer clay, or apoxie sculpt clay, you are buying an original one-of-a-kind sculpt.

It really does not matter how BJD collectors refer to the BJDs they purchase, but ball-jointed doll makers should use the proper sculpture terminology amongst themselves because it is a precise way to communicate about making BJDs.
