Sample produced by:

CHIU Ho Wan Issac

Sample date:

Sample condition:

Intact

Process-driven material

The extracted urban soil required the addition of clay to achieve the required plasticity. Different colored metal oxides are added to test the aesthetic possibilities of an old brick-making technique. The different intensities of the layers show different amounts of oxides added. The red brick (a) uses iron oxide, the black brick (b) uses manganese oxide, the green brick (c, no physical sample) uses chromium oxide.
