Zaritzky, 2008). Talc sample was supplied by Dolomita SAIC

high purity (98%), median size d50 of 5.9 ? 3.8 mm (particle size at
which 50% of thepopulation residesabove thispoint and halfresides
below this point) and nanometric thickness of 79 ? 16 nm (Castillo
et al., 2011). Glycerol (Anedra, Argentina) was used as plasticizer.
