A matt full glass brick made from glass ore. The brick is translucent and can be lit from behind. The bricks may vary in size, although the surface side (rough side) is 97mm x 197 mm and the back side is 99mm x 199mm. The thickness is around 60mm and the weight about 2.7 kg/piece. The water absorption rate is almost zero, hence the brick may be used outside as well as inside on both floors and walls.
