FAQs about Equinox glass sculpture
What techniques were used to create Equinox?
Equinox was created using kiln-casting and cold-working techniques to achieve its precise geometric form. The intricate optical effects were developed through controlled surface treatment prior to firing.
What was the process behind creating this glass sculpture?
The creation of Equinox began with a detailed sketch to refine the concept. The mold was crafted using vermiculite panels, and precise calculations were made to determine the glass shapes needed to achieve the equinox effect, where intersecting layers create optical illusions. The final composition was carefully arranged before kiln-melting. The piece underwent a meticulous 13-stage firing process, followed by several weeks of polishing to achieve optical transparency and allow the patterns to emerge within the glass.
What type of glass was used to create it?
This glass sculpture is crafted from Ohara’s eco-optical glass S-BSL7, a material free from lead and arsenic, offering a level of purity not typically found in other glass options.
How long did it take to bring Equinox to life?
Bringing Equinox to life took over three months, from concept and design to glass calculations, firing, and polishing to achieve optical precision.
