Spatter with coil bud vase

This little bud vase stands just 6 1/ 8" (15.4 cm) tall but it has a lot going on. The spatter elements (in a clear matrix) are dense, of varying sizes, and fused but not cased giving the vase a slightly rough texture. The mid-section is wound with a transparent cobalt blue "snake". The underside is unmarked.

My impression is Bohemian/Czechoslovakian sometime before WWII. Backup appreciated. :+)
