gt2P: Less CPP N2

November 18, 2018

The shape of its components is obtained with the technique given by the Catenary Pottery Printer, taking into account the variables of the amount of porcelain layers, translucency, reinforcement of the porcelain components with lava and the backing temperature to obtain the final shape fo reach components.

Less CPP is a body of work produced with a Catenary Pottery Printer (parametric analog cloth slip casting process) we developed, which creates analogue versions of parametric designs.


Less CPP N2 is a lighting series that combines two disparate materials: translucent porcelain and Chilean volcanic lava.


The porcelain slip is cast in layers into draped fabric using a Catenary Pottery Printer. The liquid clay is poured into the gentle curves of the textile, and slowly dries into a variable thickness. This can be seen when the piece is lit with LEDs, with the edges glowing brightly and the center becoming gradually more opaque.


When first exploring the combination of these two contrasting materials, we asked: what would occur if we placed bisque-fired porcelain and lava into the same kiln? We assumed at the proper firing temperature of 1300°C, the porcelain would vitrify as the lava became viscous. The result was a spectacular success: the lava flowed over the solidifying porcelain as the shape, gravity and temperature permitted.


With the slow cooling process, the lava contracts gradually, protecting the porcelain and retaining its integrity. This allows for a slim, yet strong design.

The variable translucency of porcelain can be controlled with the number of layers that are added while filling the curves, a subtle stratigraphy that can be seen when the piece is illuminated.
