Iced Coffee Glasses Set Of 2

Simons Maison's Iced Coffee Glasses Set of 2 (12 CAD, in stock) uses borosilicate glass to withstand 165°C thermal shock, enabling safe flash-chilling of hot coffee over ice to preserve delicate flavor notes. The 500 ml capacity fits a full iced latte with stirring room, and the 5-inch slender highball shape reduces surface area to keep drinks colder longer, creating distinct café-style layers when poured sequentially. However, the opening fits only standard ice cubes, not large sphere molds.

Thermal shock

Borosilicate glass withstands up to 165°C thermal gradient for safe hot coffee over ice.

Why this is supported

The borosilicate glass in these glasses

can typically withstand a sudden temperature gradient of up to 165°CWhy borosilicate glass is ideal for iced coffee — maximum_temperature_differential

, and its linear thermal expansion coefficient is

around 3.3 × 10⁻⁶ /K, roughly one-third that of common soda-lime glassWhy borosilicate glass is ideal for iced coffee — linear_thermal_expansion_coefficient

, which reduces internal stress during thermal shock. Although the glasses are non-tempered,

Capacity

500 ml glass fits a full iced latte with room to stir.

Why this is supported

The 5-inch tall, 2.75-inch wide glasses have an estimated capacity of 500 ml —

based on the dimensions (2.75" diameter x 5" tall / 7 cm x 13 cm), each glass holds approximately 500 ml (17 oz)What is the capacity of each glass in milliliters or ounces?

— which

accommodates a full café-style iced latte—a double espresso (2 oz), 6-8 oz of milk, and 4-6 oz of ice—with enough headroom to stir without spillingHow the size and shape suit iced coffee recipes — volume_for_iced_latte_builds

. The height also

The full 5-inch vertical space provides enough height to produce distinct bands of espresso, milk, and foam when ingredients are poured sequentially, replicating the striated look of professionally made iced coffee at home.How the size and shape suit iced coffee recipes — layered_caf_presentation

Ice cube compatibility

Opening fits standard ice cubes but not large sphere molds.

Why this is supported

The 2.75-inch diameter opening

easily admits standard home ice tray cubes (typically 1.25 inches per side) with ample clearance, but large sphere or rock ice molds (2 inches or wider) are unlikely to pass throughHow the size and shape suit iced coffee recipes — ice_cube_compatibility

Shape

5-inch height produces distinct café-style layers when poured sequentially.

Why this is supported

The glass dimensions (2.75-inch diameter, 5-inch height) form a highball profile used in specialty cafés for iced coffee layering.

The full 5-inch vertical space provides enough height to produce distinct bands of espresso, milk, and foam when ingredients are poured sequentiallyHow the size and shape suit iced coffee recipes — layered_caf_presentation

The estimated 500 ml capacity fits a full iced latte recipe with headroom, and the 2.75-inch opening admits standard ice cubes, enabling a practical build that results in visible layers.

Heat retention

Slender highball shape keeps iced coffee cold longer by reducing surface area.

Why this is supported

The glass's 2.75-inch by 5-inch dimensions form a tall, narrow cylinder like those in specialty cafés, and

the slender column reduces the drink's exposure to ambient heat compared to a wider tumblerHow the size and shape suit iced coffee recipes — highball_cylinder_profile

, so iced coffee stays cold longer without requiring excess ice.

Flash-chill

Withstands 165°C thermal shock and fits standard ice cubes for flash-chilling.

Borosilicate glass

Borosilicate glass withstands 165°C thermal shock for safe flash-chilling.

Why this is supported

Borosilicate glass is engineered for thermal resilience:

Borosilicate glass can typically withstand a sudden temperature gradient of up to 165°CWhy borosilicate glass is ideal for iced coffee — maximum_temperature_differential

. Its low expansion coefficient minimizes internal stress:

With a coefficient around 3.3 × 10⁻⁶ /K, roughly one-third that of common soda-lime glass, borosilicate glass experiences far less internal stress when hot espresso hits iceWhy borosilicate glass is ideal for iced coffee — linear_thermal_expansion_coefficient

. The non-porous surface doesn't absorb coffee oils or tannins, ensuring taste purity. And borosilicate resists alkaline dishwasher detergents:

Borosilicate glass resists attack from alkaline dishwasher detergents and the mild organic acids in coffee, meaning it won't cloud or etch over hundreds of wash cyclesWhy borosilicate glass is ideal for iced coffee — chemical_durability_in_dishwashers

The borosilicate construction provides thermal shock resistance and chemical durability against coffee acids and dishwasher detergents, preserving clarity over time.

The borosilicate thermal-shock resistance combined with the 5-inch height allows hot-brewed coffee to be poured directly over a column of ice, creating the rapid, even chill that defines Japanese-style iced coffee and preserves bright, delicate flavor notes.How the size and shape suit iced coffee recipes — japanese_style_iced_coffee_flash_chilling

This durability also ensures the glass doesn't cloud from repeated use, keeping the layered presentation vivid.

Official Q&A confirms:

these are non-tempered borosilicate glassesAre the glasses made of tempered borosilicate glass, or are they non-tempered?

. Despite lacking tempering, borosilicate's inherent thermal-shock resistance

ensures safety. This is due to its low linear thermal expansion coefficient,

With a coefficient around 3.3 × 10⁻⁶ /K, roughly one-third that of common soda-lime glassWhy borosilicate glass is ideal for iced coffee — linear_thermal_expansion_coefficient

, which minimizes internal stress. Additionally,

, so it maintains clarity. The set also suits specific coffee techniques:

.

The borosilicate glass used in these glasses is non-porous, which means it

won't absorb coffee oils, tannins, or flavoursWhy borosilicate glass is ideal for iced coffee — non_porous_surface

. This property also allows the glass to

rinse free of odor and stainWhy borosilicate glass is ideal for iced coffee — non_porous_surface

without scrubbing. Additionally, the glass

stays crystal-clear and taste-pure far longer than standard soda-lime glassesWhy borosilicate glass is ideal for iced coffee — chemical_durability_in_dishwashers

, as it resists alkaline dishwasher detergents and coffee acids.

Borosilicate glass is chemically resistant to dishwasher detergents and coffee acids, preventing clouding and etching even after many cycles.

Additionally, its non-porous surface prevents absorption of coffee oils and tannins, keeping the glasses stain-free and odorless.

This combination ensures the set maintains its crystal clarity and taste neutrality far longer than standard soda-lime glasses, as established by research.

Flash-chilling

Flash-chilling preserves delicate flavor notes by pouring hot coffee over ice.

Why this is supported

The borosilicate glass and tall shape work together to enable Japanese-style flash-chilling:

This technique locks in volatile aromatics that are typically lost during slow cooling.
