ShapeCrete can be cast very thin, making it possible to create jewelry and decorative objects. Using simple hardware and an old clock mechanism, Fu-Tung created this piece of jewelry as a gift for someone special.
STEP 1: The Base
The base can be anything waterproof. In this case Fu-Tung duct taped a piece of clear plastic to a piece of MDF.
STEP 2: The Form
A rubber flange washer is used to create the form walls. It is slit and a small cutout is made to capture the jewelry loop so it can hang from a necklace. The rubber flange is glued down to the plastic with spray adhesive.
STEP 3: The Knockout
To create the void in the piece to inlay the clock mechanism, a rubber disc is used. Center this in the bushing and glue it down with spray adhesive.
Wrap a narrow strip of duct tape around the outside of the form to help hold it together.
STEP 4: Mixing
Mix a small amount of ShapeCrete to a Castable Consistency. Pour it in the form gradually while vibrating to release any air bubbles.
Cover the piece with plastic and allow to cure for 24 hours.
STEP 5: Demold
Remove the rubber bushing, then pry out the inner knockout with a flat screwdriver or awl. Be careful not to damage the concrete. The edges of the piece can be sanded with diamond hand pads, sandpaper, or files.
STEP 6: Epoxy
Glue the clock mechanism in place with a strong epoxy.
