Borské bubbles

Odd photo of one of my pieces from a large collection of mid-century glass. This is an optical moulded glass sphere vase by the Czech company Borské, made in the 1950s. They came in clear, smoky quartz and green. I have the first two, and am searching for the latter.

I owe my addiction to Mark Hill (Antiques Roadshow) whose book Hi Sklo Lo Sklo got me hooked! Car boot sales and flea markets are good hunting grounds.
