Abstract

The overall goal of this project is to contribute to reconstruct the innovation mechanisms and development of ceramic production using forensic engineering techniques. Instead of optimizing materials as a driver in modern engineering, here we wish to use these methodologies, but aim to solve questions on advancement in the past fabrication process – and thus ultimately understand the key issues of a less or (un)successful design and subsequent improvement. This paper wishes to address the advantages and constraints regarding to use of basalt in ceramic matrices. By utilizing a standardized set of different test bars comprising different amounts of basalt fired at both 800°C and 1000°C, it can be concluded basalt tempered ceramics have a higher fracture toughness when compared to quartz enriched materials. It is there plausible to identify basalt as a good temper material for (ancient) earthenwares in terms of thermal (shock) activities.
