Victorian blue & white cased crackle glass vase - Bohemian I think...

This is a cool piece of Victorian glass that I picked up at the bi - monthly antiques fair last week.
It is made from two layers of cased glass, opaque white crackle over a light blue interior. The crackle layer has a matte effect, while the inside is glossy. The vase measures 10 cm tall, 6.5 cm across the top rim, & 8 cm across the clear applied, leaf - footed base.
With a lobed form & flared out top, this vase has a shape familiar to many examples of Victorian glass. I haven't seen one in this style of crackle glass, however, which is what caught my eye.
I think most likely Bohemian origin, circa 1800s - 1890s.
