** Prosser refers to the cold cast method originally invented by the Prosser brothers of Bohemia in the 19th century for making buttons. The technique consists of molding a cold paste under great pressure and then firing it. The finished product looks like porcelain and is often referred to as such. By the 1860’s virtually all beads were produced using this machine method. All Prosser beads are opaque in color and have a thin seam.

These beads were introduced into the American west and were used for trading with the American Indians, who then incorporated the beads into their crafts. As trade beads, they are sometimes also known as Prosser trade beads. In African trade, they are known as "kankanmba" or "kancamba."
