Sidney’s glass interests are closely matched with studio and commercial fabrication practices.  As demand for his work steadily grew, he realized he needed to have the plate glass circles ground and polished more efficiently and precisely.  He designed and helped create machines to help fabricate his work. That, along with advancements in adhesive technology, allowed him to laminate several circles before grinding and polishing them precisely to match his Polished Laminated Plate Glass Vase (PLPGV) design. In this series, 1/4" plate glass circles are laminated together into 3-packs before cutting, grinding and polishing into circles or bars.  The bars are then laminated between the circles in a helical pattern.
