This is such an interesting piece! The amber glass horn lays across the piece in 2 little crevices to keep it steady.  The outer glaze is a bronze color that I hi-lighted with a bit of copper patina. The inside glaze is a rich dark blue crystalline that contrasts nicely with the outside glaze. 
This piece measures  Vessel is 17"w x 9"h x 9"d, with the amber glass it measures 18"w x 10"h x 16"d
