Tetrahedral Stack

Ceramic Sculpture

Created by Frank Nemick
An elegant Raku fired sculpture, this piece is best seen in the round so that it's varying appearances can be fully appreciated! It is hand formed with clay slabs composing a stack of two tetrahedrons. A tetrahedron is a mathematics term which means a four sided solid.. This piece is held together by a steel rod which is held in place by hard, permanent sculpture foam. The colors are vibrant and permanent, with a clear raku glaze over all. It has many rough qualities that come from the raku firing, including some cracks which have been repaired in the Japanese Kintsugi method, with 22k gold leaf. As a philosophy, Kintsugi treats breakage and repair as part of the history of an object, rather than something to disguise. The area between the two tetrahedrons has 22k gold leaf.

Raku sculpture is brought up to temperature rapidly, in 30 to 45 minutes. Then, when the glaze appears nicely melted, usually around 1800 F it is removed from the kiln, the rapid cooling causing the glaze to crack. It is then put into a reduction bin, with pine needles and paper which quickly burst into flame! The lid is now tightly affixed and the vessel is allowed to sit in a smokey atmosphere for approximately 30 minutes. This allows the smoke to permeate the cracks in the glaze, showing up as black lines which are permanent.

This piece will require the top tetra's square steel rod to be slid into the bottom tetra's square steel tube, with only gentle guiding needed.
