Pure Silver - the material of this drinking vessel - was chosen due to its high thermal conductivity, to communicate the tactile experience of the temperature of the drinks to the hand, and the lips. The information of temperature "connects" the user with the drink in a more direct way.
This bowl has a pointed base - hence it can only fulfil its function when held in hand. By eating while holding the plate, the diner reaches satiety faster, which might lead him to be satisfied with less food (see Piqueras-Fiszman et al, 2013).
Through the perceptual phenomenon of sensation transference, the sensory (visual) properties of cutlery can set expectations that affect the consumption experience. This experimental spoon could enhance freshness perception, while also creating a pleasant texture on the lips and tongue.
Cutlery Weight Matters
In 2015, we published a study in collaboration with Oxford University showing that diners liked more the flavour of the food served, and were willing to pay up to 40% more for it when eating with heavier cutlery.
Better than licking fingers
Emulating the finger and stimulating the lips and tongue with a pleasant texture, Glass Goûte enhances the perceived flavour and heightens the perceived value of the food up to 40%
In the past years, we have been collecting data in several public event to assess the impact of our cutlery prototypes on flavour perception and consumption behaviours.
