Archaeological remains from the Lewis Pottery consisted of the foundation of a stoneware kiln, molds, kiln furniture (portable firing aids linked to the manufacturing process), and wasters (pottery discarded due to damage that occurred during production - underfiring, overfiring or breakage). Kiln furniture included props (vertical supports), spacers, and stackers that helped stack, separate, and
protect the pots in the kiln during firing.
The recovery of kiln furniture showed that Lewis and his potters tried to mimic the English method of making Queensware. The recovery of wasters indicated that Lewis and his potters also attempted to copy English tea cups, bowls, and decorated plates - with varying degrees of success. The variety of molds suggested that Lewis Pottery also made stoneware vessels - jugs and jars - and smoking pipes.
Examination of the Queensware wasters recovered from the site showed that the glaze was one of the main Queensware production problems Lewis and his potters experienced. Because of these glaze problems, archaeologists have been able to distinguish the unique look of Lewis Pottery Queensware from English Queensware.
Examples of Lewis Pottery Queensware have been recovered from several mid-nineteenth-century Louisville house sites. These findings indicated that the Lewis Pottery was one of the first American potteries to successfully make and sell domestic Queensware.
