Very generous. Please correct me if I have > misunderstood anything here. The freezing method "breaks" the colloid and forces the nanometer sized particles to aggregate into large particles that look like specks of pepper that fall to the bottom. Once the colloid is so "broken" the particles can not be used to form a colloid. This is a method for analysis purposes only and cannot be used to make a high particle concentration colloid.
