Natural Blue_Tannic Acid

28th October 2014

A key trend to emerge from Dutch Design week was the focus on a mono process or a mono material and to exhaust it via as many processes as possible.

Tannic Acid by Steven Banken is one example of such a project. Derived from the knowledge that oak contains a high concentration of Tannic Acid which reacts with iron oxide resulting in a dark blue, almost black colour, Steven has evolved a series of chemical reactions to push the boundaries of colour and experimentation via a series of devoted research outcomes.

The experimentation reveals the similarity in colour of two radically different materials after the natural transition of the chemical reaction.

Oak treated with red iron oxide creates variations in colour achieved by changing the intensity of the rust celebrating the simple beauty.

Working with Jetske Visser on a textile chapter of his tanici acid research, Jetske has designed a series of woven textiles dyed with natural ingredients that encourage the natural reaction as the materials come together.

Using a combination of tannic acid and iron oxide in liquid form creates a dark blue ink – silk cloth is dyed with natual blue ink whilst smaller pieces are dyed with tannic acid and placed on steel plates in order to create a reaction directly on the textiles
