Victorian glass jug with raised enamel decoration

This Victorian jug is clearly by the same maker as the preceding lidded jar. Once again, it is made from clear glass with a flashed overlay in pale pink. There is raised enamel decoration of flowers, including lily - of - the - valley (in the Victorian language of flowers it symbolised the return of happiness - no doubt why it was such a popular floral motif) & a gilded butterfly.
The jug measures 26.5 cm tall, 14 cm across the double crimped top rim, & 14.5 cm across the base, which has a partly polished pontil mark. There is an applied handle in clear glass.
I would suppose that this was once part of a set for water or lemonade, & would have had matching tumblers. However, it also makes a very practical vase for a large bunch of flowers.
Most likely Bohemian origin, & another op shop find from several years ago.
