Hand-Blown Optic Cased Turquoise Glass Tall Mantel Vase Set

Elegant pair of very tall blown cased glass tall stemmed vases.   Beautiful.  Great color.  Hand-made with opaque white glass on the interior and turquoise blue exterior.  The vertical 'melon-like' lines are a result of the outer and inner layer combining creating a light turquoise. Vessel, stem and foot were made separately, then applied together.  Maker unidentified.  We've seen vases with this style of decor described as 'Italian glass'.  They may indeed be mid-20th century Italian glass. But...they could be American 1920s/1930s art deco glass. Many American art glass makers incorporated this decor before the 1950s.  Circa 1920s - 1950s. Both are in excellent condition. Measure 15½" tall on a 4" wide domed foot.  Soft pontil mark.  Colorless applied stem is solid glass. One vase has a trapped air bubble in the foot.  The white rounded spots on images are from lighting. Towering statement vases perfect for the mantle, table or shelf.  Scarce and outstanding color.  Double gourd shape works well with Victorian, Art Deco or Retro home decors.
