Phosphorescent Gypsum 2.33/5 (18 votes)

In this project, phosphorescent powder was added to gypsum to create glowing egg-shaped vases.

The templates for the moulds were laser-cut onto sheets of plastic and assembled by hand, using masking tape to seal the joins. The ‘Super Glow Powder’ was then weighed-out and mixed with the gypsum in dry form. After adding water, the mixture was stirred until smooth and poured into the moulds. We slowly rotated the moulds for about twenty minutes to ensure an even distribution of material during the hardening process. Once the phosphorescent layer had set we repeated the process with ordinary gypsum to achieve a minimum thickness for the vessel walls.

The vases were removed from their moulds a few hours later. Charged under a light-source for a few minutes and then submerged in darkness, the white objects bathe their surroundings in a vivid shade of green light. The phosphorescent effect is further heightened by the faceted design and a texture which is smooth and cold to the touch.

Entitled ‘Tong Zi Dan‘, the series of vases was designed and constructed by Manuel Kretzer (Responsive Design Studio) and Knut Brunier (Brunier-Ernst), with assistance from Tom Roberts (University of Bristol).
