Abstract
Historically manufactured glass is also nowadays often used in listed buildings due to its special optical properties. Occasionally, they are used for artistic applications. Since the properties of non-industrially manufactured glass deviate from the harmonised European standards, special considerations must be made to verify its usability. Glass manufactured using the cylinder blowing process is part of an artistic lamp installation in an overhead situation. Securing the glass shards in the event of glass breakage is particularly challenging due to the uneven glass surface. In another project, coloured antique glass is laminated and mounted with point fittings in drill holes. The load-bearing and residual load-bearing behaviour of laminates with different degrees of thermal treatment was investigated using calculations and tests. In existing building projects, some of which are listed, the question of further usability is important, especially in the case of wired glass applications in overhead areas or as fall protection. This is illustrated by various practical examples.
