Effects of Temper on Strength of Ceramics: Response to Bronitsky and Hamer

Abstract

Results of strength tests on sand- and shell-tempered ceramics reported by Bronitsky and Hamer (1986) are difficult to interpret because of flawed experimental procedures and have questionable relevance to the archaeological record. Results from an improved procedure suggest shell-tempered ceramics as produced in prehistoric southeastern Missouri were stronger and tougher than sand-tempered counterparts.
