Coeval Fossil — negative blocks

The removable negative of a pour, cut into mouldable building blocks, keyed, and listed for assembly.

Pattern

A triply periodic minimal surface. Blocks are cut from it by a tile grid, and any that would not release are split.

Faces with a skin are solid cast. Leave at least one face open so the negative can be washed out.

Every block comes out of a two-part mould pulled straight up and down — checked on each one.
