Wire-wound beads, which begin with a 'W', are divided into three classes - I, II and III, based on construction, shape and additional decoration, after Brain, A further division of wire-wound classification is "type" which defines more closely details of shape and decoration.The type classification follows Brain's work with the Tunica material, i.e. Brain (Brain 1981 3) modified Kidd and Kidd's classification indicating that variety "of all bead types, drawn and wire-wound, take into account variations in size, degree of opacity versus translucency, color and where appropriate, qualities of surface decoration".
Following Kidd and Kidd, Brain (Brain 1981) reintroduced the eight types of drawn beads developed by Kidd and Kidd. IA rough ends (tubular form), simple construction IB rough ends (tubular form), complex construction IIA rounded ends (rounded tube form), simple construction IIB rounded ends (rounded tube form), complex construction IIIA rough ends (tubular form), layered-compound construction IIIB rough ends (tubular form), layered-composite construction IVA rounded ends (rounded tube form), layered-compound construction IVB rounded ends (rounded tube form), layered-composite construction Kidd and Kidd used "tubular form" to define a tubular shape and "rounded tube form" described a tube shape that had been altered by reheating, grinding or tumbling.For IIA1/IVA1 of the Chickasaw medium, large and very large beads perhaps 10% had a visible layer of thin clear glass.Most of the Chickasaw thin, clear glass coating was observed on the IA/IIIA Opaque, specifically the white colors.Therefore, an attempt was made to express the glass bead varieties as a manageable, solvable number of types/varieties.
The Chickasaw bead types/varieties generally exclude color as an attribute of classification.
Brain used variety as the basic unit of description, comparison and interpretation.
