Rozane Royal is an early period pattern introduced by Roseville Pottery in 1901. The pattern was introduced as a less expensive alternative to Rookwood’s popular Standard Glaze line. Roseville Royal was either undecorated or slip decorated. Early pieces were typically marked with the die-impressed “Rozane” mark, the shape number, and “R.P.Co,” but some were unmarked. Later pieces had the Rozane Ware wafer. There were 246 different shapes in the Rozane Royal line. Pieces with finely painted decoration, artist signatures, landscapes, or portraits are preferred by collectors.
