This tazza is an extremely rare and beautiful piece of early English glass made from the experimental 'glass of lead' associated with Ravenscroft and his contemporaries, who pioneered new technologies and broke away from the styles of Venice.
He was the most important English glass-maker, mainly as the inventor of flint glass. Employed by the London Glass-Sellers Company to produce a substitute for Venetian clear crystal made out of English materials, he produced much-prized jugs and goblets of fine quality, more brilliant but rather heavier than those of Venice.
