help with splatter glass vase

Hi everyone. I bought this multi-colored splatter glass vase today and could use some help with it as I am more of an EAPG kinda person. 6 1/2 inches tall, very heavy non-cased splatter glass with a ground and somewhat polished base. It has 12 ribs about an inch apart starting at the base and rising up only to fade at the neck prior to the edge ruffle. I'm pretty sure this vase is blown but the ribs do not appear to be applied. No mold seams anywhere. My question is this old? possibly Czech? I know these are still being made in various parts of the world today. Any help would be greatly appreciated...thanks CW.
