Why Do Marbles Become Paler on Grinding? Reflectance, Spectroscopy, Color, and Particle Size
Lagorio, Maria Gabriela
Journal of Chemical Education, v81 n11 p1607 Nov 2004
A qualitative description of the color-change problem, which will assist in rationalizing the change in color of marbles after grinding them using a simple physical picture and the qualitative dependence of diffuse reflectance on particle size is presented. Different approaches are discussed but it is seen that the interpretation of nanoparticles as a function of size is gaining importance.
