According to Willey 1949: 438:

There is a greater range of tempering materials in Wakulla Check Stamped than in the pottery of the Weeden Island Series. There appear to be three divisions in tempering is the use of find sand as in the Weeden Island Series types. Another division uses much coarser sand, including fairly large pieces of quartz. At the opposite end of the scale is a tempering division which is characterized by only a very small amount of find sand. Specimens of this division tend to be grade off toward the temperless Biscayne ware.

As described by Willey 1949:437-438:

Definition as a type: Gulf Coast of Florida

Ware characteristics:

Method of manufacture: Coiled or annular technique.

Temper: There is a greater range of tempering materials in Wakulla Check Stamped than in the pottery of the Weeden Island Series. There appear to be three divisions in tempering is the use of find sand as in the Weeden Island Series types. Another division uses much coarser sand, including fairly large pieces of quartz. At the opposite end of the scale is a tempering division which is characterized by only a very small amount of find sand. Specimens of this division tend to be grade off toward the temperless Biscayne ware.

Paste texture and color: Varies from granular to laminated, but is always hard and compact. Cores are usually gray or black, although some pieces have been fired buff all through. Buff-fired surfaces are common on either or both sides of the specimen.

Surface texture, color, and finish: Interiors not as well smoothed, on the average, as in pottery of the Weeden Island Series. Exteriors seem to have been completely covered with check stamping. Buff, mottled buff, or gray-black in color.

Hardness: 2.5 to 4.

Thickness: Walls from 5 to 8 mm. Bases, rims sometimes thicker.

Decoration:

Technique: Stamping wet vessel surface with cross-grooved or checked implement.

Design: Solid field of fine to medium-size checks. Squares from 1 to 5 mm. Lands of both directions of equal size. Clear but light impressions. Rather carefully applied as a rule with little overlapping. (Pl. 39, a, b; pl. 40, a-f.)

Distribution: Vessel exterior nearly, or wholly, covered.

Form:

Total vessel: Flattened-globular bowls, bowls with incurved rims, deep bowls with outslanting rims, pots, and jars with long and short collars.

Rim: Incurved, both marked and slight, outslanted, direct, slightly everted at orifice, and slightly outflared. Both unmodified and folded. Small, round exterior folds are undecorated; but the long folds have check impressions extending over fold up to lip. (See fig. 53.)

Lip: Varies from pointed to flat, although the latter are rare.

Base: Rounded in most cases.

Appendages: Triangular rim projects or 'ears.'

Geographical range of type: Gulf Coast of Florida. Possibly has extensions inland to the east.

Chronological position of type: Weeden Island II. Slight overlap into Fort Walton Period.

Relationships of type: Probably related to all the small-check stamped pottery of the Southeast of this approximate time level, including Pontchartrain Check Stamped of the Lousiana Coles Creek Period (Ford and Willey, 1939), Wheeler and Wright Check Stamped types of north Alabama (Haag, 1939), the Savannah Period Check Stamped pottery of the Georgia coast (Caldwell and Waring, 1939), and Biscayne Check Stamped of east Florida. May be a development out of a Deptford and Gulf Check Stamped continuity.
