Fiamma Art Glass, Waltham

Native Bostonians and Mass Art graduates Caterina and David share a passion for the sinuous geometries of glass. They've shaped that passion under some of the top blowers and lampworkers in the field. Their preferred aesthetic emphasizes intricate form, in stemware and vessels that incorporate the delicate curve of a seahorse's back or mischievously twisting horns over a devilish visage. Sculptures range from eerily suspended bowls held up by their frozen contents to monolithic forms bearing tribalesque patterns. And Weintraub's vetrographs are, if possible, even more inimitable: he devised the process himself, flashing light through carefully constructed glass forms onto photo paper to create images that evoke primitive life forms growing in caves or under subway seats.

The couple practice their delicate craft in a studio-cum-gallery in Waltham. Besides providing an eyeful for any glass-loving gawker, they occasionally also offer introductory classes to the multifaceted art.
