Editioned Crater Cups by Anders Hamilton
The original Crater Cup was formed by hand, each impression achieved by gently pressing fingertips into a wet slab of clay.
White stoneware casting slip is poured into the mold. It stays in the mold for about 20 minutes to build up adequate wall thickness.
The remaining slip is poured back into the bucket and the mold is left to dry for 2 hours before demolding.
The clay then dries to the point where the Crater Cup won’t be distorted when de-molding.
The cups are prepped for the bisque firing. This firing is about 1828 degrees Fahrenheit.
The first glaze applied is a liner for the interior of the cup. Contrasting glaze colors are then sprayed from alternating directions to create an embellished sense of depth and light.
The cups are loaded into the glaze firing which is roughly 2232 degrees.
This is Anders getting a lesson on spraying automotive paint from his grandfather.
