Simple Block Submittal – 080826

amphorae is neither block nor cistern, instead it is a hybrid of both that is both structural and functional

The simple block is a vertical extrusion that has a uniform thickness of 1″. The overall dimensions are 27″ x 12″ x 9″. Since the block is a simple extrusion it can simply be cast on its’ side.

With the engineer Peter Calcetas arriving in a week we have set up a series of smaller quick molds that we can use to test Ductal. This unit will be used as a tabletop planter containing one cistern and one planter. It is slightly over two feet long and 7″ wide. The thickness of the unit is approximately 3/4″ and will have three pour holes on the bottom.

Silicone testing photos

the following photos are of our silicone material tests:

Initial Material Test

Our first task was to start experimenting with different casting techniques. While working on the Brise Block we learned that the proper mold techniques quite literally make or break the concrete. For Ampohorae we will use a layer of silicone between the wood molding and the concrete cavity. Rather than preparing a full sized test we created a bowl that would match the thickness of the proposed Amphorae blocks.

The photo above is of the two bottom portions of the permanent mold. In order to cast the bowl 4 outside pieces were created and 4 inside pieces were created.

The photo above shows the first layer sealant for the lightweight MDF molds. Rather than starting with polyurethane, our first layer is a mixture of glue and water.

In the photo above Adam is applying a liberal layer of the glue water mixture.

The photo above shows the four inside pieces of mold. This model gives a close representation of the final cast piece.

We end this update with an upclose shot of one portion of the mold. The chattered edge shows some ghost lines that were added by the mill. These lines occur because of errors in our geometry and we will work on eliminating them for the next round.
