What is a characteristic feature of a dry cast's surface?

A dry cast typically has a dull surface. This characteristic arises from the materials used in the casting process. Unlike shiny surfaces, which may be associated with certain finishing techniques or materials, a dry cast’s appearance reflects its basic, unfinished nature. The dullness indicates that the cast has dried properly and is ready for use without any additional gloss or sheen.

In contrast, shiny surfaces would suggest some form of treatment or coating that is not typical of a standard dry cast. Rough surfaces are often indicative of poorly applied material or an abrasive finish, while textured surfaces might imply a design choice or a modified casting technique, neither of which correlate with the standard characteristic of dry casts. The dull appearance is essential as it helps in assessing the quality and integrity of the cast itself.
