The face-by-face (R, σ) isotherms on sucrose crystals growing from pure solutions allow us to determine the activation energies and, to some degree, the growth mechanisms for each of the F faces. Furthermore, when crystals grow from doped solutions, two other phenomena can be qualitatively interpreted: 1. the specificity of impurity adsorption as a function of the concentration, and 2D-epitaxy, when it does occur, both affecting the growth rate of each face, 2. the coloring matter effects, due both to adsorption and liquid inclusion capture under critical kinetic conditions. This effects are strongly dependent on the growth rate of the faces. By means of our experimental method (twin+single crystal kinetics) steady state growth morphology can be predicted as a function of supersaturation and temperature.
