Optical (low magnification) microscopy of the material at the different stages

 

Scale bar = 50 mm.       

 

Top. Flakes from the original latex crystal. The colors come from domains of ordered particles.

Middle. Flakes from latex-silica composite. Note the shift in colors.

Bottom. Flakes from baked silica. Although the structure could not be resolved at this low resolution, the porosity is visible.
