Dear Group, I have a Fazzoletto cased glass vase with horizontal threading on the exterior that I need help to identify. The casing has an outer an inner clear layer with butterscotch yellow and white cloud like interior layers with spots of gold aventurine. The external threading is done in a solid butterscotch yellow. The vase measures 6-1/2" tall, approximately 10-1/2" across at widest at top. The base is clear glass measuring 2-3/4" in diameter and 1/2" tall. The center 1-3/8" of the base is concave the flat ring portion of the vase stands upon shows definite signs of age wear but is not heavily worn. The vase weighs a little over 3 pound 3 ounces but has no markings of any kind.
I would really appreciate any ideas as to a definite country of origin and/or maker. Thank you for your help.
