“A liquid will always take the shape of its container. Angle is a measuring jug that makes use of this property for the measurement of liquids.
The classic measuring-jug system makes use of horizontal markings for the calculation of quantities. To pour our a specific partial quantity of liquid, the user must pour a little and then check the amount poured against the horizontal markings.
Angle combines this system with a new system of diagonal lines that indicate quantities during pouring. The diagonal lines correspond with the surface of the liquid during pouring.”
