PERLITE CALCIUM CHLORIDE

plied. So the thinking behind designing the beads is based on generating a similar sensation. Creating parametric geometry honours the natural formations in nature which relates to the project’s philosophy. The first bead is represented in silicone to establish is the design is correct in geometry, scale and suited for purpose.

The engineering of the beads requires design consideration for their form but also their ingredients. As bioceramics work on the principles of absorbing heat produced by the body, the following experiments use ingredients with these properties. Perlite is used as a substitute. It is a volcanic glass commonly used in building insulation, gardening for its heat retaining properties and is widely accessible. It also expands when heated which could create a natural compression if incorporated into textiles.

Hydrogels are hydrophilic polymers that remaining intact in water. They maintain their structures and are used for several applications such as biomedical and tissue engineering. In this case, they are the motivated form for imitating a new bead structure as featured in weighted blankets. The aim is to create a hydrogel with bioceramic thermal insulation properties. Hydrogels would be place on the pressure points and pressed to feel relaxed. As part of the outcome they could be included as a package with the clothes and kept chilled for personal use. This reinforces the interaction of the piece.

For the first recipe, Perlite is shredded and sieved into a powder form. Then it is added to Sodium Alginate and deionized water.

Perlite : 0.5g Sodium Alginate : 2g Deionized water : 100ml
