A very rare apothecary "Searce"
literally a sieve through which powder would be strained prior to
making into a tablet paste or other formulation. The top semicircular
bowl has a metal perforated sheet in its central lower section which
allows the sieved contents to pass through into the base which is
hollow and can be accessed by unscrewing the top. This lovely piece
dates to the late 19th or early 20th century. There is no makers mark
