Learning objectives
Knowledge:
Basics and details of the chemical reactions involved in the formation and use of the most important materials for the consolidation of stone.
Understanding the relationship between the properties of the different consolidating and protective materials in relationship with the stone to consolidate and their chemical characteristics.
Knowing some of the products studied in the laboratory, observing the morphological and chemical modifications directly
Capacity of Understanding: The emphasis is on the experimental approach and how to exploit the properties of individual substances and materials both to confirm what has been studied during the course of study and in the classroom, and to use their properties for practical purposes, or in the consolidation and protection of stone.
Prerequisites
None
Course unit content
The course provides the basics and insights about the chemistry of the substances and materials substances used for the consolidation of stone manufacts, both with lessons in the classroom and with laboratory experiments.
