The dome-shaped shade features curved, variegated caramel slag glass panels. This milky, marbled effect was produced by mixing different colored glass batches together during manufacturing. The lower apron is wrapped in an ornate, cast-metal foliate filigree overlay featuring molded flower patterns. This design serves a dual purpose: it structurally holds the bottom edges of the glass while embodying the nature-inspired motifs of the Art Nouveau movement. The Base features a heavy, cast-bronze or patinated spelter white metal base decorated with acanthus-style leaves and fluted columns, appears to be a gas-lamp conversion. Lamps of this exact styling were highly popular in America and were prominently produced by esteemed manufacturers like the Miller Lamp Company. I believe this lamp was made by the Miller Company.
