It is my understanding that [log in to unmask] is going to compile a bibliography of kiln excavations. To this end, I was Principal Investigator on a project in Frankfort and another in Covington where portions of kilns were excavated. Currently we are testing the Thomas Pottery in Louisville, Kentucky. The Thomas pottery was started by an immigrant Scottsman, William Thomas, sometime around 1850. By 1860, it was a sizeable manufacturing concern with two kilns. In that year census records suggest that the family had $5,000.00 invested in the works, used 21 tons of clay on an annual basis and employed 21 hands. A 20-horse steam engine provided power, probably for the jigger wheels. The Louisville business directory for 1864 notes that the Thomas Pottery produced yellow ware and rockingham ware. The pottery operated for about 40 years. Also see: Genheimer, R.A. 1988 An historical archaeological assessment of the East Main Street Phase II project in Frankfort, Franklin County, Kentucky. Cultural Resource Analysts, Inc., Contract Publication Series 88-25. This report includes a description of a relatively small, brick-lined, simple updraft beehive pottery kiln which measured 3.35 m in diameter. It contained a pair of opposing fire boxes and a system of internal flues. Both stoneware and earthenware products were manufactured including crocks, jars, bottles, plates and smoking pipes. Genheimer, R.A. 1987 Archaeological testing, evaluation and final mitigation excavations at Covington's Riverfront Development Phase II site, Kenton County, Kentucky. Prepared by R.G. Archaeological Services and Cultural Resource Analysts, Inc. for the City of Covington, Kentucky. This report contains a description of a mid-nineteenth century pottery with two, updraft, bottle type beehive kilns. Only the base of one of these was preserved; the chamber, stack and accesory structures had been removed by more modern construction/demolition activities. The brick base of the first kiln was 5.65 m in diamter. The second kiln was in equally bad shape. It is estimated to have been between 5.6 and 6.6 m in diamter. Chamber pots were the most frequently observed vessel type observed in the waster deposits. Rockingham and clear glazed mugs were also observed. In addition, annular banding with dendrites were noted on small bowls and mugs.
