A wheel-cut decorative pattern used primarily on colorless glass vessels. Ancient facet-cuts were usually concave circular, oval or elongated "rice" facets. Interlocking facets can create lozenge shapes or hexagons. The technique was probably invented in Italy in the last quarter of the first century A.D. The earliest facet-cut vessels have facets over the entire surface. Around 250 A.D. it became popular to facet-cut only areas of the vessel. Shallow wheel-abraded facets are were used on some forth century tableware. Around the mid-forth century in Scandinavia, Germany and Mesopotamia distinctive styles developed with thick-walled vessels with deep facets.
