The Use of Volcanic Tuff in Braşov’s Buildings. The Recovery of a Phase in the Town’s History and Aesthetics

Summary/Abstract: One of the rocks employed extensively in the 19th century in the center of Braşov is the volcanic tuff. This was used both for complex components with high artistic value and for functional purposes, from monumental columns of representative buildings to socle veneers of modest houses. The tuff’s mineralogical properties determine both its type of degradation and intervention methodology in restoration works. Following the observations on volcanic tuff elements in the above-mentioned area and the restoration of some components made of this rock, several general and common features of volcanic tuff were identified. This essay presents as well the main types of restoration processes and the manner of approaching theoretically the most important of them.
