LITERATURA TEMATU - Preventive Conservation of Stone Objects, W.Domasłowski (red.) -

Pozycja w języku angielskim !!!

This publication is intended as a manual for students who specialize in restoration of stone historical objects. It is complementary to lecture materials delivered to the students of the second year, after they have got acquainted with the bases of chemistry, physics, geology and petrography. Fundamental knowledge of these subjects makes it possible to understand and get to know the information material contained in the present book.
