Botanical Casts

Made by: Rachel Dein

Material: clay, plaster

Process:  She makes impressions in wet clay, and then pours plaster directly over it. The clay captures the most intricate details. Each clay mould can only be used once, making every piece unique.

Removal – chemical & Physical

How things change over time can be frightening but also fascinating! Statues and sculptures of limestone or other more sensitive materials is heavily affected by what we call Acid rain. As the rain falls on the material, it slowly starts to eat of parts, little by little, until you no longer can recognise the initial motive. The method of making something finished, straight or closed, to later remove chosen or random parts is a method used in many fields, art, architecture etc. Siri Derkert osed this way of working on her artwork in the subway station Östermalmstorg in Stockholm. So by first covering a dark part of the wall In white concrete, and later apply force to revel the underlying color and then create lines.

MISTAKE? – pour lines and air bubbles

When pouring concrete into a form there are several things that can go wrong. Can these features be turned into an asset? Can they be controlled or steered in any way? Air or water bubbles is a common problem but can create a beautiful pattern. Although it is hard to control the placement and intensity of the bubbles. Another issue when casting large amount of concrete is the lines created in-between different pours, because the color do differ between different bags of cement and is affected by many other aspects which is hard to control and will therefore result in slight color differences. This can also be turned into an asset.

CAST IN EXISTING / NEGATIVE SPACE (ant + house)

Casting into an already existing mould could sometimes result in unbelievable shapes. Other times you can very clearly predict the outcome, which still can be very powerful. Representing a void. The fist two images show art instalations made by Rachel Whiteread who in the first image casted an inverted bookshelf and in the second image an entire town house. The last picture and in the video aluminium has been poured into ant hills and pumpkins. Pouring into a hidden underground system of paths and voids the outcome is always a surprise. You can never tell how tall an anthill reaches underground until you cast into it. The pumpkin as a mould is more of a safe card. You know what you gonna get.

Lapiaz in Haute-Savoie, France

There are channels of dissolution which are more or less parallel. The water leaves traces  on a limestone ground. Also the ice and how it is melting makes fissures in the stone. As a result the rock is jagged, with holes, cracks and fissures.

wax casting

made by: cnc milling, melting, cooling

material: wax

process:

This ‘non-waste-casting’ is made out of industry wax. The desired shape is formed by CNC milling and the material can be fully used again after melting it down. This way of casting is very precise – even for complex geometries.
