Just like the universe is made from the smallest parts, the atoms, Core have been built from small beads. It is an experiment to see how small parts can build a bigger shape. The process starts with single iron beads, being soldered together. Each bead lets the structure grow further, just like corals in the sea. A flame heats up the iron beads wherever it hits them and this way the shape is created by the path of fire and the brazing solder. The shape of the piece can be adjusted as well as the size and the lightness or density of the structure.
