Silica, 2 oz "Quick Clear"

Silica is a form of hydrated silica that works by absorption. Each particle is a hollow silica honeycomb with pores just large enough to let haze-forming proteins in. As each particle absorbs the protein, it falls out of solution and forms a firm sediment on the bottom of the fermentation vessel. You need to stir silica into the secondary fermenter a few days prior to bottling or kegging. Use 1/2 ounce per 5-gallon batch of beer.
