Glossary
waste mold
This term is used in two contradictory ways. In its most common use: a piece mold made from a model (usually of clay or wax) when the model must be broken apart (wasted) in removing it from the mold. The other use: a mold from which only one cast can be taken, because the mold must be broken apart and discarded in order to release the cast. This is how lost-wax casting is accomplished, for instance. The use of this term is highly problematic then, unless the user immediately explains the meaning intended.
ukiyo-e
Japanese for 'pictures of the floating world'. Ukiyo-e were popular in the seventeenth to nineteenth-centuries, and depicted kabuki actors, landscapes, and folk tales.
Example: Kitagawa Utamaro's Five Kinds of Ink from the Northern Provinces, early 1790's
ultramarine
Blue pigment originally made from ground lapis lazuli. French ultramarine is an artificial substitute.
undercut
Carving to create an overhang; a recess or awkward angle in the surface or form of a three-dimensional object which would prevent easy removal of a cast from a mold. Molds should be designed to eliminate this problem. Ways to cast objects with overhangs include using piece molds and waste molds.
underdrawing
Drawing preliminary to other work, and incorporated into it, thus deprived of independent artistic value. An example is the underdrawing in fresco and panel painting, such as sinopia and abbozzo.
underpainting
The layer or layers of color on a painting surface applied before the overpainting, or final coat. There are many types of underpainting. One type is an all-over tinting of a white ground. Another is a blocked out image in diluted oil colors that serves as a guide for the painter while developing the composition and color effects.
