An Adjustable Mould for the Casting of Glass Voussoirs for the Construction of Fully Transparent Shell Structures

Compared to flat sheets of float glass, cast glass components have a thicker geometry and thus a high buckling resistance. This buckling resistance in combination with the high compressive strength of glass make cast glass components suitable for the construction of fully transparent shell structur...
