Loetz Ausführung 83, Imperial Red with Leaf Green, st PN II 7058, ca. 1910

This Loetz decor, with densely packed copper-colored aventurine dust inclusions, is often mistaken for Murano glass. Ausf. 83 comes in three basic grounds, Deep Red, Blue, and Imperial Red, sometimes with an enameled layer (in the case of lamp shades). This version in imperial red has a thin outer layer of leaf green, which gives it a brownish cast.
