Consider two teapots. The first one is decorated with stems of rose?s and leaves. It is perfectly functional; the handle and spout have been balanced and constructed, along with the body and lid of the teapot, for optimal use. This would be a functional object, with artistic additions or attention. The second teapot is shaped completely like a rose. The main body of the teapot is a rose flower, the spout a rosebud extending out on a narrow stem and the handle a complete leaf, perpendicular to the rose, opposite and in the same plane as the rosebud spout. The teapot does not really serve tea; the handle is too delicate and the spout not hollow. It's a sculpture of a teapot.

Modern? and Contemporary materials include the environment, textiles, glass, sand?, water, liquid crystals, many other man-made materials, as well as any found-objects.
