Czechoslovakian spatter with reflective iridescence

Because the surface of this vase is so reflective, it is difficult to photograph. After tries with several backgrounds and lightings, these were the best I could get. It has an interesting iridescence that seems to float somewhere within the clear casing rather than on it. Otherwise, it is red and "black amethyst" spatter on a thin white ground with that heavy iridescent clear casing. The top rim is sort of sloppily cut and fire-polished. The interior throat has been sprayed and reheated giving it a radiant golden glow. This explains (I guess) the reason for the ground-out pontil mark on the underside.

It stands 5¼" (13.2 cm) tall with a 3" (7.6 cm) diameter at the hips. The vase is unmarked. In the style of the Kralik "Iris" decor, but I guarantee I don't know if it is.
