Working with cork and clay is a challenging task. We experimented with creating a mixture of cork and clay, by pouring powdered cork into clay, but the result was not satisfying. We also tried to combine the two materials in bigger elements, but clay cracked and contracted after drying. Thus, we decided to work only with cork, making finger joints that were very stable and created an interesting lighting effect.

group15 _ 3d printing

For the 3d printing excercise we created a platonic solid using the rhino polyhedron extension. We fabricated 8 joints, which were connestd with plastic sticks. The finishing of the holes in the joints was not accurate ( they needed to be a little bit melted) and we should consider making deeper holes, so that the model would be more stable.

group15 _ clay mold

For the milling excercise our team chose to test clay. We milled a foam mold to pour powder clay in it, creating twice an organic shape. The procedure helped us realize the challenges we had to face working with clay. The mold needed almost a week to dry and there was a small, but notable contraction on the fabricated design which was different for the two shapes we created, probably due to the different percentages of powder clay and water between the two molding procedures.

For the laser cutting excercise our team worked with 3mm cork sheet. The material in such thickness is very flexible but quite brittle. We tried several designs, from which the one that could be synthesized in a sphere was this cutout sphere. However, the fabricated result was extremely unstable.

Name
SIO-2 ARGILA Clay (100% natural pottery clay)

Formula
SiO2 (53.53%), Al2O3 (20.50%), Fe2O3 (0.67%), TiO2 (0.98%), CaO (8.58%), MgO (0.30%), Na2O (1.17%), K2O (2.20%), L.O.I (11.63%)

Description
SIO-2 ARGILA is a 100% natural pottery clay, very pure and fine milled clay in white color. Its plasticity is well balanced in order to achieve best results during the modeling, drying and firing. The color remains intact after firing (recommended to be fired in a kiln between 970 and 1050ºC)

Extraction Process
SIO-2 ARGILA Clay is a 100% natural product, composed only from clay (chemical analysis shown in Formula) and water
