Resumo

Prehistoric potters used a wide variety of materials as temper, or filler. Although temper selection has often been assumed to be the result of purely cultural factors, recent research indicates temper had technological functions as well. Impact and thermal-shock resistance data of a range of kinds, grades, and amounts of temper are presented. Test results indicate that the use of finely-ground tempers in general and burned shell temper in particular produce briquettes that are significantly more durable than briquettes incorporating other materials.
