Mixtures {colloid}| with particle diameters 1 to 100 nanometers are translucent or opaque, separable by fine membranes, and settle slowly. Solutions can have many small particles, which attract an opposite-charge ion layer, which then attract an ion layer. Layers prevent good precipitation. Hydrophilic colloids are viscous, hard to coagulate, and gel-like. Hydrophobic colloids are sols, make curds, and are easy to coagulate.
