We test every tumbler to brim capacity

In high-volume restaurant dining rooms, uncalibrated glassware produces pouring variance that eats away at liquor cost margins. The Cylindrical Heavy-Base Tumbler 380ml (SKU GW-TMB-380-HB) is manufactured from annealed soda-lime glass with a dedicated 14 mm solid glass footing that lowers its center of gravity by thirty-eight percent compared to standard pressed barware.

Digital vernier caliper measurements across four cardinal points confirm uniform rim wall thickness. The brim capacity measures 380 ml (12.8 fl oz) with an allowable tolerance of positive or negative three millilitres, allowing an operational beverage fill of 300 ml with standard 45 mm square craft ice cubes.

Our operation does not copy marketing claims from overseas packing slips. Ivan Petrov has managed our glassware catalog operations since 2021 under registered business entity IP Petrova, completing exactly 240 verified commercial glassware SKU cards over the past twelve months.

When a hospitality operator commissions a catalogue project with us, every tumbler, highball, and goblet undergoes hands-on physical verification. Each evaluation records dry tare weight, dishwashing chemical resilience over sixty commercial wash cycles, and perimeter rim tension to guarantee that kitchen crews receive realistic breakage forecasts before placing warehouse stock orders.

Commercial clients compare glassware sourcing services on five specific pillars: total product card count, filter depth, inventory integration, content population, and technical SEO structure. We deliver projects following four structured steps that prevent assortment drift:

This tumbler is engineered exclusively for chilled beverages, table water, and spirit pours on ice. It is manufactured from soda-lime glass rather than borosilicate, which means it cannot withstand sudden temperature differentials greater than 42°C.

Usage guidelines exclude hot tea brewing, espresso service, or pre-heated table punches. Pouring boiling water directly into a room-temperature soda-lime glass will cause thermal base fractures. Venues requiring thermal shock resistance should reference our borosilicate ware section or inspect our ground stopper replacement cards for hot culinary equipment.
