~ Dale Hardiman// Klag

Thanks to Dale Hardiman for sharing his design & inspiration behind the 'Klag' chair - interesting not only for it's form but for it's construction. An inspired use of materials.

An experiment consisting of a new concrete substitute and it's structural ability. By creating a form with 3 legs, the properties of the single material chair and its relationship with the structure are crucial. The chair is cast in components, and then attached using the same material.

Currently in Tarong and Tarong North, SouthWest Queensland, there is roughly 1,100,000 tonnes of fly ash. Fly-Ash is a coal combustion by-product, and due to Australia's continuing demand for coal fired power, we are left with a huge waste disposal problem. Don Browne (Exile-Global-Technologies) is the creator and sole manufacturer of ET-21, which is a fly-ash and resin based product. It is water resistant, 100% recyclable, lightweight and heat resistant.

What inspired/inspires your design process - be it film, music, materials, experience etc:

I'm really fascinated with materials, natural and artificial, and love discussing possibilities and potentials of material outside their common use. The actual process of creation and degradation are the main focus of my design process, which is how the object may not have an actual form until further exploration of that material.

Was Klag the result of your own brief or the result of a competition or project response?

Klag was the result of a university brief to design an outdoor furniture item. After being introduced to Don Browne (ET-21 inventor) we discussed the possibility of the material, and with it's structural capability wanted to push it as visually and structurally as far as possible using the chair as a common typology in furniture design.

Is your design process a 2D sketch or 3D materials exploration?

My design process generally begins with a material, with the form generally being left until the end of the design process. Ideas are then generally sketched but the majority of the design process is material experimentation and prototyping.
