Sorry Sue, girasol is the Italian for sunflower but also the term they use to describe milky white opalescent glass.
Also, I am confident this was made by/for Salviati as there is a blue version with a similar shape (four bulges instead of eight) and more importantly the exact same enamel band, it is shown on page 16 of Exquisite Glass Ornaments, edited by Rosa Barovier Mentasti.
