Division & Growth glass tiles- story by MaterialDistrictDivision & Growth are glass tiles with colourful patterns integrated into them. The process for these tiles is to make glass rods in various colours and designs within the hot shop using molten glass from a furnace. Once cold, these rods are cut up and fused into a flat sheet in a kiln. The pattern looks like the growth of an unknown life form under the microscope. The tiles are usually 15 x 15 cm, but custom sizes and shapes can be made. This technique can also be used to make small tableware such as dishes and coasters or larger architectural pieces.
