How do you know milk is simmering?

When milk is simmering, small fine bubbles rise from beneath the liquid and break through to the surface. The bubbles appear at different and distant spots on the surface of the milk.

The more it simmers, the more it bubbles. Later on, the bubbling becomes constant but the milk does not boil. It progresses and steam appears on the surface of the milk. Afterward, the milk begins to thicken and reduce in quantity.
