The MELTING TRADITION project is based on the technology of metal casting. The main aim of the TOOL collection is to work with a metal artefact as the main factor of the working process. Working with a negative – a form which is being produced without a tangible model, either intuitively or consciously. Spaces in aero-concrete forms created by these metal tools are filled with liquid aluminium. Then the form is broken while discovering little surprising shapes of the final results.
