Project #2: 009_tall0104

Our final molds in action and the tiles that are resulting:

So far the molds are holding up famously. We’ve wrapped the “inside” aspects with black plastic to resolve a release concern and the effect is a very shiny and plasticized interior, or hub, of our core tile. We had worked on differentiating the “inside” and “outside” surfaces of the tile and this pragmatic production decision carries this surface treatment forward.

The added benefit of transparency  This has allowed us to greatly reduce the occurrence of voids and the resulting failed pours.

After fifteen casts the mold, both MDF and PETG elements, are doing very well.

Some of the tiles that have been cast: hub tiles on the left under the monitor, core tiles in the center, and the molds on the right.

The hub tile has received the same “plastic” treatment on it’s center element. Here it was purely out of functional necessity so that we could release the cast from the mold without compromising either.

Though the tiles will require some light cleanup, the interior webs of plaster that slip easily into the plastic-wrapped crevices create a very interesting effect. It would be possible, using a ridged form such as the MDF and PETG here and a plastic barrier, to control the degrees of opacity. We’ll try a dry run assembly of our wall and evaluate then whether or not to leave the happenstance membranes.
