Abstract:
     Molten glass is made into beads by quenching in water. After ball grinding, said glass beads are sorted into coarse, middle and fine grades, which are spread in a mould in three layers, where the content of fine beads is not less than 20% for lower layer and 10% for middle layer. the collected beads then go through heat treatment in kiln. Colouring liquid prepared with organic suspension is mixed with said beads and then dried before they are spread. Obtained artificial crystalline stone is very similar to natural marble and granite.
