Mary Pat Wallen | Process (Lost Wax Method Broken Down)

Many artists start by creating a sculpture out of reusable clay. They then take this clay creation and apply a rubber mold over the clay, followed by a plaster mold over the rubber. This plaster mold allows the artist to make multiple pieces by brushing wax onto the mold to  create duplicate sculptures out of wax. 

Wax stage: She skips this part and spends countless hours over a hot crockpot of wax creating one-of- a-kind sculptures.

Gating/Slurry stage: Then the wax sculpture is gated and dipped in a slurry of plaster, allowed to dry and then placed in a kiln.

Kiln stage: The temperature of the kiln is so hot that the wax evaporates and creates a hollow crevice that is replaced with hot molten bronze.

Sand blast stage: The layer of plaster has to be sandblasted. Sandblasting is tedious, but crucial, as plaster residue would add weight to the final sculpture.

Patina stage: Multiple layers of acids are applied. Patinas are applied cold or with a torch. The sculpture is then sealed with multiple layers of wax.

From the Artist:

My work portrays my personal journey through life. It is messy. It consists of multiple layers of what the world might see as mistakes, but I see as beauty. It is seeing the beauty among the rust and corrosion of humanity.... viewing the holes or rusty crevices not as decay, but as opportunities to let your soul shine. I like to call it controlled chaos, the yin and the yang, or better yet, my wabi sabi moment!
