Nanopublication — Ceramic Structural and Surface Methodology for Complex Forms

Context

At 28×34×17 centimeters, this sculpture presented significant structural challenges due to its complex geometry of enclosed volumes and intersecting curvilinear planes. I engineered internal chimneys—hollow vertical passages—to allow moisture and gases to escape during the firing process, preventing thermal stress fractures that commonly occur when thick ceramic [2] walls or enclosed spaces trap expanding air. This technique is essential when working at this scale with forms that cannot be hollowed uniformly.

I used petite chamotte—fine-grained grog (pre-fired ceramic particles)—mixed into the clay body to provide structural integrity and reduce shrinkage during drying and firing. The chamotte creates a more stable matrix that can withstand the thermal expansion and contraction cycles of high-temperature firing while supporting the cantilevered planes and thin-walled sections of the cubist composition.

For surface treatment, I applied beeswax and pigments to achieve tonal differentiation between planes. The dominant yellow-green patina covers most surfaces, while darker brown tones mark recessed areas, the base, and interior voids. This chromatic separation helps articulate the geometric decomposition—each plane reads as a distinct element through color as well as form. The beeswax creates a subtle sheen and aged quality, enhancing the metallic appearance produced by the glaze crystallization during firing.

These technical decisions—internal structure, clay body composition, and surface treatment—work together to make the complex cubist form materially viable while supporting its visual reading as distinct geometric components in unified sculptural space.
