Made circa 1902 the iridescent surface decoration is called Silberiris. To get this effect, it is covered in a stencil. Wax is applied and then the vase gets an acid bath. The uncovered areas subjected to the acid leave the etched design behind. Its a technique that Steuben would copy some 20 years later. The electric iridescence is so bright, these pieces are sometimes mistaken for Carnival Glass.
