22C – ceramic vessel for storing warmth @ Embracing Innovation 4

Ceramic, Phase Change Material (PCM), Thermochromic, Photochromic and Photoluminescent pigments.
22C is a collaboration with Joan Barrass (Ceramics) and Linda Davy (Everything !) designed for the Embracing Innovation 4 exhibition opening July 24 at Crafts ACT in Canberra.

22C-craftACT-july-01This thermodynamic ceramic vessel is a heat battery that has been designed for the climate in Canberra. The vessel contains 2 litres of inorganic salt solution known as a Phase Change Material (PCM) that acts as a concentrated heat mass when it changes from solid to liquid at 22C.

AAAA2876The surface is coated in thermo-chromic pigments chosen to indicate the state of the PCM inside it. On cold winter mornings the blue surface indicates the inside is solid. As it warms up it turns yellow to indicate the inside is melting.

AAAA2885At the end of a sunny day the white surface indicates the inside is liquid. In the evening when the temperature drops below 22C the surface turns back to yellow and then blue again as it solidifies and releases stored heat.

AAAA2884When sunlight falls on the surface a pattern of photo-chromic purple rings indicate that the solar input is charging up the thermal battery. At night the surface glows purple with photo-luminescent pigments to indicate stored energy is being released.

22C-EmbracingInnovation-00Embracing Innovation Vol. 4, the fourth instalment of the Centre’s Embracing Innovation exhibition series, presents the work of craft practitioners and designer makers who have embraced cutting edge technologies into their practices. A selected group exhibition comprising six individual artist and two collaborations Embracing Innovation Vol. 4 will present work from artists and researchers from leading Australian and international research and academic institutions.
