The brittle nature of glass prevented real structural applications of glass in architecture up to the 1990s. As a result of intense research, nowadays tempered architectural soda-lime-silicate glasses (SLS) are particularly capable for modern architectural, structural and solar applications due to their superior mechanical strength and resistance to thermal break. In contrast to annealed commercial SLS, tempered SLS is investigated with detailed microscopic analysis and systematic scratch tests. The major influences on the scratch behaviour (humidity, temper stress etc) are presented. The typical crack system of an indentation is derived from analytical calculations of the three-dimensional stress field beneath the indenter.
