Idea Development

The project began with form exploration and material experiments. Inspired by origami principles, my goal was to create a layered and flowing structure. Early paper models helped understand the fluidity of the shape, but the rigidity of paper imposed some limitations. To refine the form, I explored different proportions and curves while maintaining the essence of the original concept.

Production Process

plaster mold and model making

My first model was made of paper, and since I couldn't create a plaster mold from it, I recreated my model using a plastic floor covering material. Then, I made a plaster mold from this version and used it to create a new model.

Before casting, everything was coated with shellac, followed by mold release soap to prevent the plaster masses of the mold and model from sticking together.

Once the new plaster model was cast, I refined and modified its shape, making adjustments to achieve the final form I envisioned for my porcelain cup.

To create the final plaster mold for the porcelain vessel, the model was once again coated with shellac and mold release soap.

First, a small amount of plaster was poured for the base. Once it dried, the model was placed on top of it. Thick paper was wrapped around the model as a frame to create space for the mold. The plaster was then mixed and poured around the model.

The mold was made in three parts: the base, the middle section, and the top. The middle section was split into two halves to facilitate the removal of the model.

The mold is left to dry in a warm place for approximately two weeks.

Once fully dried, the porcelain casting process can begin. First, the outer part of the mold is secured with tape to keep it in place. Then, the liquid porcelain is poured into the mold, which must remain filled for a certain period depending on the desired wall thickness.

After approximately 15 minutes, the excess porcelain is poured out, and the mold is left to drain for about 30 minutes. The top lid is then removed, and any unwanted edges are trimmed. At this stage, the remaining porcelain walls need about an hour to harden sufficiently. This ensures that the piece can be removed from the mold without deformation, allowing for necessary refinements before being left to dry further.

porcelain firing and glazing

After the first firing, the glazing process can begin. Before this step, the objects must be cleaned of any dust to prevent imperfections in the glaze. Now, using tongs, carefully dip the pieces into the glaze.

The glaze protects the porcelain from discoloration and stains, enhancing its durability and finish. However, since the glaze would cause the piece to stick to the kiln shelf during firing, it is essential to wipe off any glaze from the bottom surface. Finally, the pottery is fired again, completing the process and achieving its final form.
