Ceramic and Glass Technologies
Knowledge about the technological processes for the production of ceramic and glass materials. Identification and characterization of the raw materials, with particular emphasis on the industrial production of traditional ceramics. Identification, description and classification of the methods used in the processing of ceramic and glassy materials. Analysis of the main environmental aspects related with the processing of ceramics and glasses.

Lectures: oral communication helped with presentations (ppt), examples from some internet sites and utilization of the blackboard.
Theoretical-pratical classes: problem solving sessions related with subjects treated in theoretical classes.
Pratical classes: laboratorial classes, using the facilities from the Ceramics and Glasses Lab. at DCM.
Frequency- Gained by performing the lab essays.
Evaluation Methods -By performing 3 mid-term tests (T1, T2 and T3) or by final exam. In case that mid-term tests are performed, in order to get exemption from final exam, the grade resulting from both tests, T=(T1+T2+T3)/3, has to be at least 9.5.In case that only final exam is performed, the exam grade (E) has to be at least 9.5. For the students that perform mid-term tests, Final Grade = 0.6T+0.4A, A corresponds to the grade obtained from the evaluation of the lab essays. For the students that perform final exam, Final Grade = 0.6E+0.4A.
Powder processing (grinding and milling, methods for powder characterization). Glass technology (raw materials; typical compositions for commercial glasses; glass melting; glass fining; glass forming methods; thermal treatments (annealing and tempering). Glazes (composition; ceramic substrate-glaze compatibility; defects in glazes; colouring ceramic pigments, methods for glaze application). Shape-forming processes (pressing; slip casting; plastic methods). Drying (effect of temperature and humidity on drying rate). Ceramics densification. Kilns and furnaces (kilns for ceramic industry and kilns for glass industry).
