Workshop:

Casting the Canal

Underwater Dining: Building the Surface

19 Sep 2026

What happens to a material after it is cast? What continues to live, grow, or decompose inside it?

Building on the material experiments from Sampling the Canal, this workshop moves from small-scale testing to the collective casting of a full-size table surface made with materials gathered from the Oosterdok.

What will you do

The workshop begins with a presentation of the tile experiments produced during Sampling the Canal: Underwater Dining — A Material Survey by Federico Rizzo. Participants will look at how the different recipes behaved and how these tests informed the mixture used for the table.

Working in small groups, participants mix mortar in 40L tanks using the drill mixer: canal sand, hydraulic lime, water, and chopped or pressed algae integrated directly into the mix. Groups rotate between mixing and applying the material, sharing the physical process of casting the full surface.

Algae fronds are pressed in and partially submerged, sediment clusters are distributed unevenly, tool marks can be left visible or smoothed, allowing the final table to record the materials, gestures and decisions involved in its making.
