Cobalt Blue Bubble Glass Tumbler 8.7 cm Rim 10 cm Tall 330 g Deep Tone Bar Cup

Cobalt Blue Bubble Glass Tumbler 8.7 cm Rim 10 cm Tall 330 g Deep Tone Bar Cup is a glass tumbler built around a tapered body with a wide rim and a 6 cm base in cobalt blue translucent, with dense internal bubble texture. It is produced in our glass workshop for buyers who need a repeatable decorative programme rather than a one off sample, and the piece shown here carries the a saturated cobalt body with bubbles through the wall, built as the blue partner to our amethyst tumbler.

Cobalt is the most requested colour in coloured glassware because it holds its tone when backlit, which suits bar display shelves. Every unit is annealed in a controlled lehr so that wall stress stays within our breakage specification, and dimensions are checked against the measurement sheet printed on the photography. The result is a glass that looks individual on the shelf but behaves predictably in a container load.

• Saturated Cobalt Tone: The deep blue stays readable in low light and photographs strongly for drinks menus.
• Internal Bubbles: Texture sits inside the wall, so grip and appearance never wear away.
• 330 g Body: Solid enough for tray service while staying economical to ship.
• Wide 8.7 cm Rim: A generous opening takes ice and bar tools for long drinks.
• Tapered Profile: A 6 cm base under a wider rim keeps the glass stable once filled.
• Pressed Build: Uniform wall thickness keeps breakage planning predictable.

This glass tumbler is aimed at cocktail bars, hotel bars, night venues and event hire. Buyers typically place it in a range that needs one recognisable decorative accent without moving to a full bespoke mould, and because the body is a standard production shape the tooling cost is already absorbed into the piece price.

In service the glass is expected to move between back of house washing and front of house display several times a day. The surface withstands standard commercial detergents, and the rim geometry has been kept simple so that stacking and racking do not put point loads on the lip. For retail programmes the same item can be boxed as a single unit or combined with the matching pieces in our range to build a story around colour and pattern.

Sampling buyers usually test three things: whether the decoration survives twenty dishwasher cycles, whether the base sits flat on a granite or marble surface, and whether case pack dimensions match their pallet plan. All three can be confirmed with a stock sample before any production deposit is placed.

Each piece is packed in a moulded pulp or corrugated divider inside a five layer export carton, with a printed sleeve available for retail programmes. Case pack quantities are set so that a full pallet loads without void fill, which keeps freight cost per unit down for mixed container orders.

Production is inspected at three points: incoming glass quality, decoration placement, and final packing. AQL inspection follows the usual 2.5 major and 4.0 minor plan unless a buyer specifies otherwise, and we keep a retained sample from each run so that repeat orders can be matched for colour and pattern density.

Hand washing with a soft sponge is recommended where a decorative surface is present, and dishwasher use is acceptable on a normal cycle at moderate temperature. Avoid sudden temperature change such as pouring boiling liquid into a chilled glass, since thermal shock remains the most common cause of breakage in any annealed glassware. Stored correctly, the piece is designed for years of daily use.
