The structure and volume of the pear glass ensures that the tea is drunk at the optimal temperature and volume. The pear structure is for the tea to cool down in the glass late and proportionally in terms of heat exchange. In such a structure, the tea cools proportionally, starting from the surface to the bottom of the glass – the mass at the bottom of the glass is kept warmer. In addition, the specific volume of the pear glass was not chosen by chance. This is the volume that serves to take tea into the body in effective and proportionate portions.
