Caustic (optics) - Wikipedia
In optics, a caustic or caustic network is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.

12.5 Solid-Liquid Equilibria - Chemistry LibreTexts
A freezing-point curve (freezing point as a function of liquid composition) and a solubility curve (composition of a solution in equilibrium with a pure solid as a function of temperature) are different ways of describing the same physical situation. Thus, strange as it may sound, the composition (xA) of an aqueous solution at the freezing point is the mole fraction solubility of ice in the solution.
