Building the Internal Steel Armature
The sculpture begins with the fabrication of a strong internal steel armature. Using the approved concept drawing as a guide, the artist measures, cuts, positions, and welds the steel framework to establish the bulldog’s height, length, stance, and overall proportions. This internal structure supports the weight of the sculpting materials and provides the strength needed to maintain the sculpture’s form throughout the creative process. Careful attention is given to the position of the legs, body, head, and shoulders so the finished bulldog will have the powerful stance and commanding presence envisioned for Tracy High School.
Building the Bulldog’s Form with Foam
With the internal steel armature completed, rigid foam is attached around the framework to begin building the bulldog’s body. The foam creates a lightweight foundation for the sculpture while establishing its overall mass, stance, and proportions. Layers are carefully positioned around the body, head, shoulders, and legs, then carved and refined to develop the bulldog’s basic anatomical form. This stage allows the artist to confirm the sculpture’s size, balance, and powerful posture before the clay is applied and the detailed sculpting begins.
Sculpting the Bulldog in Clay
After the foam foundation establishes the bulldog’s size and basic form, clay is applied over the surface and shaped entirely by hand. The artist gradually develops the muscular body, powerful shoulders, sturdy legs, broad head, facial wrinkles, and determined expression that give the mascot its distinctive character. Throughout this stage, the sculpture is carefully reviewed from every angle to refine its anatomy, balance, stance, and proportions. Fine details and surface textures are then added until the completed clay model fully captures the strength, pride, and spirit of the Tracy High School bulldog.
Creating the Sculpture Molds
When the clay sculpture is completed and approved, the mold-making process begins. Because of the bulldog’s size and complex shape, the sculpture is carefully divided into multiple sections. A flexible silicone rubber mold is applied to each section to capture the sculpted anatomy, facial features, wrinkles, and surface textures. Strong outer support molds are then created to hold the flexible molds securely in their original shape. Together, these precisely fitted mold sections preserve every detail of the clay sculpture and prepare the bulldog for the next stage of the lost-wax bronze casting process.
More of the Bulldog’s Journey Is Coming Soon
The Tracy High School bulldog is now moving into the next stages of the traditional lost-wax bronze casting process. Future updates will include wax patterns, bronze casting, welding and assembly, metal finishing, patina, protective clear coating, and the completed bronze mascot statue. Check back as we continue documenting its transformation from an original concept into a lasting symbol of Tracy High School pride.
