WRelief is a sculptural technique where the sculpted elements remain attached to a solid background of the same material. The term relief is from the Latin verb relevo, to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. What is actually performed when a relief is cut in from a flat surface of stone or wood is a lowering of the field, leaving the unsculpted parts seemingly raised. The technique involves considerable chiselling away of the background, which is a time-consuming exercise. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, especially in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be just added to or raised up from the background, and monumental bronze reliefs are made by casting.
WA hydraulophone is a tonal acoustic musical instrument played by direct physical contact with water where sound is generated or affected hydraulically. The hydraulophone was described and named by Steve Mann in 2005, and patented in 2011. Typically, sound is produced by the same hydraulic fluid in contact with the player's fingers. It has been used as a sensory exploration device for low-vision individuals.
WPatina is a thin layer that variously forms on the surface of copper, brass, bronze and similar metals, or certain stones, and wooden furniture, or any similar acquired change of a surface through age and exposure.
WA pedestal or plinth is the support of a statue or a vase, and of a column in architecture. Smaller pedestals, especially if round in shape, may be called socles. In civil engineering, it is also called basement. The minimum height of the plinth is usually kept as 45 cm. It transmits loads from superstructure to the substructure and acts as the retaining wall for the filling inside the plinth or raised floor.
WA protome is a type of adornment that takes the form of the head and upper torso of either a human or an animal.

WA statue is a free-standing sculpture in which the realistic, full-length figures of persons or animals are carved or cast in a durable material such as wood, metal or stone. Typical statues are life-sized or close to life-size; a sculpture that represents persons or animals in full figure but that is small enough to lift and carry is a statuette or figurine, whilst one more than twice life-size is a colossal statue.
