Chinaware In order to develop physical models from a greater logic this course aimed at digital fabrication and material computation. The students were working with the material of liquid porcelain in order to create digitally designed and fabricated objects. They were exploring the material’s distinct properties and used them to inform and reiterate their design. To produce the final shape produced casts in which the material was then poured into. The process of pouring revealed the material constrains which were further utilised for the desired design purpose. In parallel to material experiments they explored various ways of modelling digital shapes with programs such as Rhino and Grasshopper.

Tong Zi Dan Tong Zi Dan is a series of generatively designed vases made from dental gypsum. The objects were produced during the CAAD Wahlfach Praxis Course Chinaware, ETH ZĂźrich. The shapes were designed together with Knut Brunier and produced with the help of Tom Roberts. The initial egg design was randomly populated by a cloud of points which formed the center for surfaces that trimmed the shape perpendicular to its curvature. A generative algorithm was then used to create the area of all faces within a certain min/max range. Finally the faces were unrolled and laid onto a flat sheet to allow the production of the mold with a laser cutter.
In our experiment the gypsum was enhanced with thermochromic pigments in one mixture and phosphorescent in another. It was then poured into the sealed molds and pivoted for a few minutes until the gypsum solidified. The process was repeated for two more times to ensure a minimum wall thickness. After the mixture had dried the vases were removed from their enclosing molds. Since thermochromic pigments are heat sensitive, they changed their color in response to a rise in temperature. The previously blue vase turned to white, the gypsum‘s base color, when exposed to a fan heater. Another interesting effect was generated by the phosphorescent pigments. During daylight the vase looked normal, but in darkness it started to glow and create a different atmosphere.
