Faceted-spheroidal mold-pressed beads have been manufactured in Bohemia since the 18th century. Evolution of manufacturing technology has resulted in the creation of bead attributes that can readily be observed on beads from archaeological contexts. Many North American archaeological sites contain examples of this bead type; but few reports have identified the attributes, much less recognized these beads as mold-pressed. Enough evidence now exists to suggest that some of these attributes have temporal significance for dating archaeological bead assemblages. Terminus post quem dates for faceted-spheroidal mold-pressed bead attributes are hypothesized, and a strategy for future research is suggested so that a more precise temporal sequence can be constructed.
The Society of Bead Researchers is a non-profit scientific-educational corporation founded in 1981 to foster historical, archaeological, and material cultural research on beads and beadwork of all materials and periods, and to expedite the dissemination of the resultant knowledge. Membership is open to all persons involved in the study of beads, as well as those interested in keeping abreast of current trends in bead research.
