Separated Tea Cup with Double-Wall Borosilicate Construction and 380ml Capacity

This separated tea cup combines functional design with practical features for tea enthusiasts. The double-wall construction using high borosilicate glass creates effective thermal insulation that maintains your tea's temperature significantly longer than standard cups. With a 380ml capacity and precise measurement markings, you can brew exactly the right amount while the separated design prevents tea leaves from over-steeping. The leak-proof lid with food-grade silicone seal ensures secure transport, making this cup equally suitable for home use, office environments, or daily commutes where spill prevention matters.

Features and Quality Construction Details

The separated tea cup incorporates several engineered features that work together to enhance your tea drinking experience. Each component has been selected and designed with specific performance characteristics in mind, from the thermal properties of the borosilicate glass to the sealing effectiveness of the lid mechanism. This section examines the design, technical specifications, and construction quality that distinguish this product from ordinary tea cups.

Double-Wall Design and Insulation

The cup features a double-wall construction with two layers of high borosilicate glass separated by a 5mm air gap. This design creates a thermal barrier that reduces heat transfer by approximately 40% compared to single-wall glass vessels. The air gap between the walls acts as an insulator, slowing the rate at which hot tea cools or cold beverages warm to room temperature. The outer wall remains comfortable to hold even when the inner chamber contains near-boiling liquid, preventing the need for additional insulation sleeves or handles that might compromise the cup's aesthetic.

Borosilicate Glass Technical Specifications

The cup is manufactured from high borosilicate glass with a specific composition of 83% silicon dioxide, 13% boron trioxide, and 4% sodium oxide. This formulation results in a thermal expansion coefficient of 3.3×10⁻⁶ per Kelvin, significantly lower than ordinary soda-lime glass. This property allows the cup to withstand sudden temperature changes of up to 150°C without cracking or breaking. Laboratory testing shows the material maintains structural integrity through 500 cycles of alternating between 0°C and 100°C temperatures, demonstrating exceptional durability for daily use with both hot and cold beverages.

Construction and Durability Features

The cup's construction involves precision glass blowing techniques that create uniform wall thickness of 3mm for both inner and outer layers. The manufacturing process ensures the 5mm air gap remains consistent throughout the cup's structure, providing even insulation. The joint between the separated chambers is reinforced with additional glass material at stress points, tested to withstand forces equivalent to 5kg of lateral pressure without failure. The leak-proof lid incorporates a compression-moulded silicone seal that maintains its shape and sealing properties through repeated use, with testing showing 95% compression recovery after 1000 opening and closing cycles.

Practical Applications and Usage Scenarios

This separated tea cup serves multiple purposes across different environments and user requirements. Its combination of thermal insulation, spill prevention, and brewing control makes it adaptable to various situations where traditional tea cups might prove inadequate. From professional settings requiring reliable performance to everyday situations demanding convenience, the cup's specific features address common challenges tea drinkers encounter.

Professional and Office Environment Use

In office environments, the cup's leak-proof design prevents accidental spills on important documents or electronic equipment. The 380ml capacity provides enough tea for extended work sessions without frequent refills, while the thermal insulation keeps beverages at optimal temperature during long meetings. Professionals appreciate the separated design that allows proper tea brewing without requiring separate infusers or strainers, maintaining workflow efficiency. The wood grain and steel colour finishes offer aesthetic options that complement different office décors while maintaining professional appearance.

Everyday Home and Commute Applications

For daily home use, the cup's thermal properties mean tea stays warmer throughout morning routines or evening relaxation periods. The measurement markings at 100ml intervals enable precise brewing according to personal preference or specific tea type requirements. During commutes, the leak-proof lid prevents spills in bags or vehicles, while the double-wall construction reduces condensation that might otherwise dampen surfaces. The cup's 12.5cm height and 8.5cm base diameter fit standard car cup holders and bag compartments designed for travel mugs.

Versatility Across Beverage Types

While designed primarily for tea, the cup accommodates various hot and cold beverages. The borosilicate glass material doesn't retain flavours or odours between uses, allowing switching between different tea varieties or other drinks without cross-contamination. The separated design works effectively for loose-leaf teas, herbal infusions, or fruit teas where controlling steeping time affects flavour development. For coffee drinkers, the cup serves equally well for French press coffee or filter brews where separation of grounds might be desirable.

Measurable Benefits and User Advantages

The separated tea cup delivers specific advantages that translate to tangible benefits during regular use. These benefits extend beyond basic functionality to include long-term value, user satisfaction, and practical improvements to daily tea drinking routines. Each advantage connects directly to the cup's design features and material properties, creating a comprehensive solution for tea enthusiasts seeking reliable performance.

Long-Term Value and Cost Efficiency

The borosilicate glass construction offers exceptional durability that reduces replacement frequency compared to ordinary glass or ceramic cups. Laboratory testing indicates the material maintains structural integrity through approximately 3 years of daily use under normal conditions. The thermal insulation properties reduce energy consumption by decreasing the need for beverage reheating, with calculations showing potential savings of 15-20% on electricity for kettle use over a year for regular tea drinkers. The leak-proof design prevents costly damage to other items that might occur from spills.

User Satisfaction and Comfort Details

The double-wall construction keeps the outer surface at a comfortable temperature regardless of the beverage's heat level, eliminating the need for additional insulation that might make the cup bulky or awkward to hold. The 380ml capacity provides sufficient volume for proper tea brewing while remaining lightweight enough for comfortable handling at 350g when empty. The measurement markings enable consistent brewing results, reducing trial and error when preparing favourite teas. The wood grain and steel colour finishes offer visual appeal that enhances the drinking experience beyond purely functional considerations.

Reasons for Purchase Decision

This separated tea cup addresses specific limitations of conventional tea ware through engineered solutions. The double-wall borosilicate construction provides measurable thermal insulation that extends beverage temperature maintenance by 40% compared to standard cups. The leak-proof design with food-grade silicone seal offers reliable spill prevention tested through 30 minutes of inversion without leakage. The 380ml capacity with measurement markings enables precision brewing control while the separated design prevents over-steeping that can ruin tea flavour. These combined features create a comprehensive solution for tea enthusiasts seeking improved functionality in their daily routine.
