Beckjord casts are of three sorts. He typically makes clay models and studies for carvings. Some of these are sufficiently appealing to be valued in their own right. These he casts for his collectors and patrons.
In the case of most carvings, one exemplar is sufficient if not more than so. However occasionally one succeeds so well that it merits duplication in a cast. The sculptor has made them in plaster, clay, cement, fiberglass and paper mache, but he prefers bronze for its longevity.
Finally, Beckjord makes models that are unrelated to carving. He generally finishes a plaster cast from a waste mold, then makes a permanent silicone rubber mold for casting in bronze and other media.
