Magnificent & Rare Shimmering Clear Leaded Sandwich Glass Vase "Leaf Pattern with Pinched Trefoil Form" containing 4 Flower Chambers. Circa 1830's to 1840.
Identified Sandwich "Tapered Hexagon" pattern Pressed Glass Base with central Knob and Joining Glass Wafer. The Knob Seam is slightly twisted from attaching the 3 parts together while the glass was still hot. The Glass Wafer,or connecting Glass Coin system, was also used on many early Sandwich Glass 2 part Oil Lamps.
The High Quality Silver Sheen of the Vase is due to the high content of Lead inside the glass. The flint glass bases contained a lesser amount of Lead was the normal procedure to cut costs.
The Top compartment-ed Vase section was first Molded with a "Leaf Pattern" then Pinched & Hand Tooled upward into 4 sections while the glass was still hot, forming the Trefoil around the 4th central opening. The Base is a 3 part pressed glass with a hollow bottom. See the 6 Side Views in the photos. (Since it's a Hex Base, their are 6 possible multiple side views)
Only known examples are found in Clear or Canary Yellow Glass.
Condition : Near Mint Condition, Glass top edges and Base are Amazingly undamaged. No cracks, fractures, chips,or flea bites. Normal sharpness around the inside perimeter of the base, which is from mold removal at the time of factory production.
