Bohr

This work was named after The Bohr Model formulate by Niels Bohr a Danish physicist born in 1885. The Bohr Model depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus — similar in structure to the solor system, but with electrostatic forces providing attraction, rather than gravity.

The many concentric rings of this sculpture and the simmering yet clouded cast glass bring to mind spiraling energy, but definitely captive by its own mass.

This work measures 16x16x22, and weighs in at over 60 pounds, making it the heaviest of the series.

Bohr is composed of the following elements:

Metal Marble - Metal Marbles are discussed in About Metal Marbles.

 Iridescent Cast Glass - The other whitish ring of Bohr is composed of crushed iridescent glass that was used as the raw material for casting the solid two inch thick ring. There is a cast ring on the top and on the bottom of Bohr. Iridescent Glass as defined by the Spectrum Glass company: "A surface treatment in which a layer of metallic oxide is bonded to the hot glass surface just after sheet-forming, resulting in a colorful, shimmering effect." The iridized glass, as is all of the glass for Bohr, if from the Bullseye glass company. Again, the integration of metal and glass used to create the iridescent glass was important for the overall theme of this series.

Cast Glass - In the center of Bohr's ring is a 5/8 piece of black cast glass with irregular outer edge which divides the sculpture into halves.

Cast bronze -Unlike Thesis, Bohr's cast glass iridescent ring is sheathed by a bronze casting. It completely envelopes the glass except where the bronze is cut away to reveal the glass. The combination of cast bronze, and multiple pieces of cast glass make Bohr a deceptively massive work.

 Lath Turned Wood - The black body of the sculpture is composed of turned pieces of wood which form the central spiral of Bohr. The wood was tuned, texturized, stained, coated and sealed with a polyurethane and silicone carbide mix. The silicone carbide (fine black blasting sand) was added to the poly to reduce gloss, add texture, and create a subtle sparkle. The ends of the spirals are copper plated Corian which house the metal marbles. Corian was used because it holds fine detail without wood grain showing and is easily copper plated.

Additionally, the mother mold for the cast bronze was created from a piece of turned cherry wood.
