Silica Gel (Kieselsol), NALCO 1072, 30% colloidal Silica.

Used with bentonite or gelatin to give a more compact lees and with the latter as a tannin substitute.

When used with gelatin it should be added at least a day earlier. It may be used by itself to remove colloidal hazes and can be better with protein hazes when the pH and dielectric points are farther apart.

Normal usage is 0.5 to 1.5 grams per gallon (0.8 to 2.5 mL).
