Sizing - Wikipedia

Sizing or size is a substance that is applied to, or incorporated into, other materials—especially papers and textiles—to act as a protective filler or glaze.Sizing is used in papermaking and textile manufacturing to change the absorption and wear characteristics of those materials.. Sizing is used for oil-based surface preparation for gilding (sometimes called mordant in this context).
