Victorian cased rainbow spatter glass jug vase with thorn handle

This Victorian glass jug vase is made from three layers of cased glass - clear over rainbow spatter, with a white interior. It measures 30.5 cm tall, 8.5 cm across the crimped & spouted top rim, & 9.5 cm across the base, which has a polished out pontil mark. The vase also has an applied thorn handle in clear glass. Perhaps Bohemian?
