Rotationally Cast Mirrors

Overview

I became interested in casting materials in early 2017 after gaining access to a shop space with proper ventilation. This project explores roto-casting — a process involving two-part polyurethane that is measured, colored, and mixed, then poured into mold cavities. An HDPE lid is secured, allowing the mold to rotate and coat the interior with cured polyurethane evenly.

Materials: Polyurethane + Glass mirror

Process

Each frame is cast by pouring two-part polyurethane into a spinning mold. The sealed mold rotates, allowing the material to cure evenly along the interior surfaces. No two casts are identical — variations in material temperature, color mix, mold speed, and pour timing produce a range of surface textures and wall thicknesses across each piece.
