Our Vintage Crackle Glass Bulb Ornaments Mixed Designs come as a set of six different designs. These small hand-blown glass ornaments are inspired by vintage mercury glass bulbs. The glass bauble has a crackle glaze that is applied to the exterior when initially blown. This gives the glass an aged, crackled look. Each bulb is topped with an ornately detailed bronzed colored cap and finished with an organza ribbon for hanging. Each approximately 1.18” Diam.
