limestone

Introduction

While researching ancient lime mortar technology, we encountered a number of cases in published archaeological studies that refer to the use of ashes and charcoal as aggregates in mixtures. These mixtures were tested in a small number of experiments, and this paper presents the results.

Introduction

During the Bronze Age, the craftspeople of the eastern Mediterranean practiced a form of reuse or recycling: fragments of mortar were used as aggregates in lime mixtures intended for walls or floors (Shaw, 1973, p.222; Brysbaert, 2003, pp.168-173, pp.175-176; Jones, 2005, p.220; Brysbaert, 2008, p.118). Such a mixture was found in a house in the Akrotiri settlement of Santorini, in a part of the wall that was intended to be painted (Jones, 2005, p.220).

In 2006 the remains of two lime kilns from the Roman Empire period were discovered in Tuněchody near Chrudim in the Czech Republic. These finds became the object of a detailed multidisciplinary research project resulting in hypotheses on the use of the kilns. Based on these hypotheses experimental research was designed (Thér et al. 2010)...
