What are glass granules?

glass granules is an industrial product made of borosilicate glass. It is the basic material for our dyed glass granules . It contains almost no foreign particles or false colours. The granulate cut out of big glass cullet, it therefore has, in contrast to the rather flat glass chips grains, a beautiful, round grain shape. There's also a greater variety of available grain sizes, <1mm, 1-2mm, 2-4mm, 4-10mm, 20-40mm. Even in dry condition the dyed material keeps the beauty of its colours.
