5 Oz Glass Appraisal

Bormioli Rocco Rock Bar 5-ounce Juice Glass

This is a 5-inch tall tempered glass tumbler produced by the renowned Italian manufacturer Bormioli Rocco, specifically from the classic 'Rock Bar' collection. The glassware is constructed from thick, transparent soda-lime glass, featuring a distinctive paneled or fluted design on the lower two-thirds of the vessel. This faceted architecture transitions into a smooth, slightly flared cylindrical rim at the top, a design choice engineered for stackability and durability in high-volume environments. The base is heavy and weighted, providing stability and showcasing the clarity of the material. Visible markings on the bottom typically include the 'Bormioli Rocco Italy' stamp, identifying its origin and manufacturing heritage. The glass exhibits a clear color with high transparency, though this specific piece shows some light surface scuffing and cloudiness indicative of regular use and mechanical dishwashing. The item is characteristic of late 20th to early 21st-century commercial-grade barware, prized for its thermal shock resistance and classic European aesthetic. The craftsmanship is industrial-grade, focused on uniformity and resilience, making it a staple in both professional bistros and residential kitchens.
