| Elements of chemistry and chemistry laboratory
(objectives)
1) Knowledge and understanding: at the end of the course, and following the commitment of practical study, the student has an adequate knowledge of the definition and use of laboratory glassware and equipment preparatory to the correct understanding of the following Conservation and restoration study programs, which involve laboratory experiences and the application of chemical methodologies.
2) Ability to apply knowledge and understanding: At the end of the course and following the individual and group practical commitment, the student achieves an adequate preparation which, together with the other more specific knowledge that he will acquire later on, will allow them to move and operate in application and innovative fields, including international ones. The student will be able to use chemical methodologies for the execution of specific applications in the field of cultural heritage. He will then be able to orient yourself in the choice of different experimental approaches, making this choice also on the basis of the practical knowledge acquired.
3) Independent judgment: At the end of the course and following the individual and group practical commitment, the student is able to critically interpret any experimental results relating to laboratory techniques applied to the conservation and restoration of artistic and cultural heritage. The student is able to evaluate possible qualitative aspects related to the use of reagents or treatment mixtures. The autonomy of judgment will be mainly oriented to an assessment of the achievable quality in the finished work based on the choice of treatments themselves.
4) Communication skills: At the end of the course and following the individual and group practical commitment, the student is able to communicate and share knowledge related to the discipline to interlocutors and collaborators of the same level and non-specialists. He is able to constructively interact, in relation to the discipline studied, with other people who are part of multidisciplinary work groups often present in restoration sites and laboratories for the conservation and restoration of cultural heritage. These skills are also developed thanks to individual practical commitment, to the critical discussions of the experimental results, which represent the moment of synthesis of the study path.
5) Learning skills: At the end of the course and following the individual and group practical commitment, the graduate student has developed a certain degree of critical approach. He know how to find all the useful information to contextualize a problem, through the use of the tools offered, appropriate scientific literature and he know how to choose the practical approach and the most correct methodology for solving the problem.

(objectives)
1) Knowledge and understanding: at the end of the course, which also includes the Chemistry Laboratory module, and following the commitment of individual study, the student has an adequate knowledge of the chemical concepts preparatory to the correct understanding of the following Conservation and restoration study programs, which involve basic and more advanced concepts of general and inorganic chemistry as well.
2) Ability to apply knowledge and understanding: At the end of the course and following the individual study commitment, the student achieves an adequate preparation which, together with the other more specific knowledge that she will acquire later on, will allow them to move and operate in areas of innovative applications, including international ones. The student will be able to use the fundamentals of chemistry for specific applications in the field of cultural heritage, including for the application of specific methods and eco-sustainable treatments. The student will then be able to orient himself in the choice of different approaches, making this choice also on the basis of the knowledge acquired.
3) Independent judgment: At the end of the course and following the individual study commitment, the student is able to critically interpret any data relating to the evaluation processes of the conservation and restoration techniques of artistic or cultural heritage. The student is able to evaluate possible qualitative aspects related to the use of reagents or treatment mixtures. The autonomy of judgment will be mainly oriented to an assessment of the achievable quality in the finished work based on the choice of treatments themselves.
4) Communication skills: At the end of the course and following the commitment of individual study, the student is able to communicate and share knowledge related to the discipline to interlocutors of the same level and non-specialists. He is able to interact constructively, in relation to the studied discipline, with other people of similar cultural background. These skills are also developed thanks to individual commitment, written tests and oral tests, which represent the moment of synthesis of the study path.
5) Learning skills: At the end of the course and following the individual study commitment, the graduate student / graduate student has developed a certain degree of critical approach. You know how to find all the useful information to contextualize a problem, through the use of the tools offered by appropriate scientific literature.
