{"type":"firestarter.listing","listing":{"id":"lst_tUPNgwk8","product_name":"Graycano Cupcano Glass Small – Borosilicate Coffee Glass, 220ml","category":"Drinkware","description":"The same bowl design, sized for shorter drinks.\nThe Cupcano Glass Small is a wide-bowl borosilicate glass designed for espresso, short blacks, and smaller milk-based drinks. Its wine glass-inspired shape gives the liquid more surface area at the top, which allows aroma to collect before each sip. It holds 110 ml usably, with 210 ml total capacity to the rim.\nThe handleless form keeps the profile clean and puts the warmth of the drink directly in your hand. The borosilicate construction is lightweight, thermally stable, and clear enough to show the colour of whatever is inside.\nBorosilicate Glass and the Bowl Shape\nBorosilicate glass handles thermal stress better than standard soda-lime glass because of its lower coefficient of thermal expansion. It can take hot liquid without the wall thickness needed to compensate, which keeps the glass light and the walls thin. The Cupcano Glass uses borosilicate throughout.\nThe bowl shape is wider at the top than at the base. This increases the surface area of the liquid, giving aromatic compounds more room to release before each sip. The same design logic is used in wine glassware, where shape is chosen specifically to direct aroma toward the nose. Applied to coffee, the effect is a drink that presents more of its character before it reaches the palate.\nThe Glass\nThe Cupcano Glass Small is a single-piece borosilicate vessel with the same wide-bowl form as the Large, scaled for shorter drinks. It is well suited to espresso, short blacks, piccolo lattes, and any coffee served in a smaller volume. The Cupcano Glass Large is available separately for filter coffee and larger milk-based drinks.\nWhat’s in the Box\n•       Cupcano Glass Small  x 1\nSpecifications\nCapacity  110 ml (usable) / 210 ml (to the rim)\nMaterial  Borosilicate glass\nCare  Hand washing recommended.
