i.2 air as constituent
i.3 air as formative agent Air pressure is used in the scientific, industrial, artistic and architectural fields to cast, create and configure material form. Contact with air brings about changes in material properties and structure, and can be a direct or indirect method of form-finding and of fabrication. A membrane filled with air, such as a balloon, becomes rigid and behaves like a solid object. Air bubbles or inflated membranes have thus been used as low-energy, lightweight formwork to be cast upon are various scales. Air can also become a constituent in a material and alter its inherent properties at the molecular or structural level. The addition of air bubbles to different materials produces varying results. The blowing of compressed air into or over the surface of a material moulds it into unpredictable forms that maybe planned or intuitive, tailored or unique.
