Sculptor Fran Volz Takes ReboundŽ 25 to the Next Level
Fran Volz is an artist and mold maker living and working in the Chicago, IL area.He has developed new media for creating his works, including creating sculpture with foam and snow, but he always finds himself returning to a classic form – bronze.His website describes some of the influences that continue to influence and inspire his sculptural works:
“While Volz enjoys working with different media, his real love is creating monumental statues in bronze. He likes the permanence of bronze and the classical appearance these works have. Volz has been influenced by a variety of sources. He enjoys the classical styles of such artists as Michelangelo, DaVinci, Rodin and Houdon; the whimsical subjects of Norman Rockwell; the dynamic poses of Marvel Comics superheroes and the fluid, flowing lines of Disney and Vargas characters. Like his snow sculptures, Volz likes to create bronze works that touch people. For this reason, he concentrates on human form compositions; and less on abstracts.“
This gallery features a monumental task – creating a mold from an oversized original sculpture of a Greek god.Mr. Volz found Rebound® 25 silicone rubber to be an extremely versatile solution to this problem. He engineered a complex, multi-piece mold as a step in the ‘lost-wax’ process that would eventually transform his water-based clay original into a bronze masterpiece.

The completed sculpture is ready for the mold making process. Volz carefully plans mold making process before applying any rubber to the sculpture.
Volz creates a brush-on mold using ReboundŽ 25 silicone rubber from Smooth-On. He creates a resin and fiberglass support jacket to give the flexible rubber a rigid structure.
The ReboundŽ 25 silicone mold and rigid support jacket are completed piece by piece up the entire figure.
More mold sections are added piece by piece around the shoulders and neck of the sculpture.
Eventually the work reaches the face of the sculpture. Volz creates a shim with pieces of playing cards. The shim separates two sections of a support shell.
The first layer of ReboundŽ 25 is applied in a thin section.
ReboundŽ 25 will pick up perfect detail from the original model. It is also soft and flexible, making it suitable for projects with significant depressions or undercuts.
A second layer of ReboundŽ 25 is applied after the first has partially set. Volz pigments the second layer to ensure thorough application over the first. This layer is also thickened to more quickly build up the silicone mold.
More thickened ReboundŽ 25 is applied to the face of the model. Layers of ReboundŽ 25 are applied until the desired thickness is reached. 3/8'' (1 cm) is typically adequate.
The ReboundŽ 25 is allowed to fully cure. A resin and fiberglass support jacket can then be created. Due to the shape of the face, the support jacket must be created in two pieces.
The second half of the support jacket is applied over the ReboundŽ 25. The small bumps of ReboundŽ 25 serve as registration keys which lock into the support jacket. Keys ensure the mold will be properly seated in the support structure when casting.
Volz color codes different sections of the support jacket to make re-assembly easier.

The completed shell: Once the entire mold and support jacket have fully cured, the original can be removed.
With the support jacket removed, the ReboundŽ 25 silicone mold can be peeled away from the original model. ReboundŽ 25 is flexible and stretchy enough to be removed from deep undercuts.
ReboundŽ 25 silicone rubber perfectly reproduces even the smallest detail of any original model.
Mold sections are re-assembled in preparation for casting. ReboundŽ 25 molds can be cast into many times with many different casting media.
