This project builds on an assortment of previous photoluminescent experiments, where photoluminescent powder was mixed with translucent silicone and spread into thin sheets. The glow of the sheets intensified as the material was folded onto itself, creating layers that amplified the emitted light. For this project, the same combination of silicone and photoluminescent powder was used to create larger sheets of photoluminescent material, resulting in a tablecloth and four placemats.

The base of the photoluminescent tablecloth is a 100% cotton, close-weave white fabric, layered with a thin coat of translucent silicone mixed with blue photoluminescent powder in a ratio of 100:1. When applied to the fabric, the silicone changes from white to translucent, enhancing the light intensity as it is rolled or folded. Additionally, the border is intentionally left untreated to create a reflective core around which the rest of the tablecloth can be rolled.

The placemats are made from the same fabric but incorporate yellow photoluminescent powder and blue thermochromic powder to create alternating stripes. This design allows the placemats to exhibit two types of visual changes: during the day, the blue stripes turn green when a hot plate or cup comes into contact with the surface; in the dark, the yellow stripes glow.

The tablecloth is intended for use in remote outdoor settings with minimal artificial light, such as camping meals, picnics in the park, or beach outings. During the day, the tablecloth can be laid on a table or the ground, where it absorbs sunlight across its surface. As the sun sets and darkness falls, the glow becomes more prominent.

Afterwards, one can easily fold or roll the cloth, creating different geometries that shape the lighting experience. If objects or people are on the cloth during the day, unique patterns are formed on the surface, further influencing the final visual effect. While the photoluminescent material is not bright enough to fully replace exterior lighting, it provides an ambient glow that adds a warm, intimate atmosphere.

In conclusion, this tablecloth originates from the simple observation that mixing silicone with photoluminescent powder creates a glowing, flexible sheet whose effect varies depending on how it is manipulated. The final result is easy to use, performs well in a range of environments, and encourages collaborative interaction as diners create their own unique folding and rolling patterns.
