Victorian cased spatter glass jug.

This small, Victorian jug is made from three layers of cased glass - clear over multicoloured spatter, with a white interior. It measures 8 cm tall, 7 cm across the top rim, & 4.5 cm across the base, which has a rough pontil mark. For a small item, it is quite thick & heavy. There is an applied handle in opaque white glass. No idea of where this hails from...maybe Bohemian? The spatter swirls rather nicely on the base, & reminds me of antique marbles.
