Bronze sculptures are produced in a series, after which the mold is destroyed. The original clay or wax is not intended to survive, and although it sometimes does, it is the bronze castings that are considered the artworks. Historically, for a bronze to be considered an original work of art, it had to be part of an edition of 12 or less. Because of greatly expanded markets many artists produce much larger editions, but I prefer to keep my editions small. Sculptures are not reproductions, and each casting is individually poured, chased, detailed, numbered and signed. A restricted edition ensures that each sculpture is perfect and unique.

Other mediums are used to achieve specific effects, such as wood for its lightness, or polyurathane for its flexibility and durability. Patinas may be natural or painted to achieve lifelike realism. Whatever the material, a complete grasp of the animal's structural anatomy and movement is required to achieve three dimensional authenticity.
