The hydration behaviour of the small-temperature regular quicklime is much more different than large-temperature commercially generated quicklime, made out of precisely the same stone. The small temperature substance hydrates a lot more slowly and gradually, reaches a reduced temperature and maintains a peak temperature plateau for for a longer time as opposed to large-temperature quicklime. The traditional quicklime also provides approximately 50% non-hydrated residue throughout the assessments. This suggests an origin for ?�lime inclusion??texture in historic mortars. Mortars generated applying regular incredibly hot mixing procedures are petrographically similar to historic mortars.
