ABSTRACT:
A hollow glass brick consists of two half-bricks (1, 2) fused to one another. On the internal surface of at least one of its walls (4, 5) provided for the passage of light, there is provided a finely structured surface embossing. The surface embossing is made of a design having a wavy profile whose wavelength is 200 to 1000 .mu.m and whose wave depth 10 to 80 .mu.m. These embossed fine structures give the impression of glass bricks having frosted interior surfaces. They prevent one from seeing through the brick and provide a high degree of diffusion.
