Description
An expert-led session by Rose of Jericho demonstrates how rigorous mortar analysis, combining traditional wet‑chemical methods with modern microscopy, guides effective, performance‑based conservation of historic masonry while emphasising accurate sampling, skilled interpretation, and ongoing professional education.
Key Points
- Scientific Analysis Drives Conservation Decisions
Detailed chemical dissolution, microscopy, SEM, and XRD reveal binder‑aggregate ratios, hydraulicity, and additives, enabling repairs that are compatible with heritage fabric and prevent premature failures. - Performance Trumps Like‑for‑Like Replacement
Modern conservation favours mortars matched for permeability, strength, and durability rather than exact historical recipes, reducing long‑term risk to historic structures. - Expertise, Sampling, and Cost‑Efficiency Matter
Reliable results depend on correct sampling techniques, Rose of Jericho’s historic material library, and experienced interpretation—while balancing advanced testing against project budgets.
Learning Objectives
- Explain the core laboratory and microscopic techniques used to characterise historic lime mortars for conservation.
- Assess why performance‑based criteria often take precedence over strict like‑for‑like mortar replacement in preservation projects.
- Recognise the importance of correct sampling methods and expert interpretation in producing actionable conservation recommendations within budget constraints.
