Mixed Metals

Mixed metal sculptures are made from a combination of Bonded Bronze and Bonded Aluminum. Additionally, in some instances, various colors of Bonded Bronze have been combined by using different alloys of bronze particles in the emulsion. Bonded Bronze and Mixed Metal sculptures are easily maintained by dusting them and occasionally wiping them with a damp, soft cloth.

Mixed Metals / Clear

Mixed metal sculptures, combining elements in clear resin, are, once again, made from a combination of Bonded Bronze and Bonded Aluminum. Once cast and patinaed, the elements designated to be clear are then cast onto the sculptures, i.e., the clear veil on the Mysterious Veiled sculpture illustrated. Bonded Bronze and Mixed Metal sculptures incorporating clear resin part are also easily maintained by dusting or wiping them with a damp cloth.

Bonded Bronze

For the Bonded Bronze material, Mack uses finely-ground bronze with a resin bonder. In the inverted mold, the heavier bronze particles migrate through the resin resulting in a high density of bronze on the surface of the sculpture. The sculpture is etched and polished, and a patina is achieved that has the same appearance as a molten Cast Bronze sculpture...but, without the weight.

Bonded Sand

This material is made from resin that has been impregnated with an extremely fine, pure white sand. The sand gives the material added strength, and is very stone-like in appearance. On many of the earlier Bill Mack images, the sand has also been bonded to the surface. The surfaces of newer images have been finished in a very durable matte while coating which makes them easy to maintain.

Natural Sand

Natural Sand is similar to Bonded Sand. However, in Natural Sand, the artist uses a darker, neutral color sand that is considerably more granular than the fine white sand in Bonded Sand. The resulting surface is marble-like in appearance and is extremely strong and durable. It is also easy to care for, using a damp cloth to periodically clean the surface.
