I took part in a really exciting workshop looking at the potential of conductive glass. This was run by Justin Marshall at Northumbria University and Jeffrey Sarmiento from the National Glass Centre in Sunderland (thank you both). As an exploratory workshop, we conducted a range of experiments looking at conductive materials suitable for embedding in the glass while considering varying firing temperatures and the effect on both the glass and the conductive elements themselves. Processes ranged from hand crafted metal filings and wire to a greater reliance on tools like the water jet cutter and sand blasted glass masked to create grooves for filling with conductive materials like graphite powder. A lot was learned about the choice of materials and the resulting visual effect, such as the reddening of copper when combined with other powders in the firing process.
Alongside supporting the workshop more generally, I was able to try a few experiments and create two simple conductive designs. A first design was a simple stroke sensor that was mirrored by the textured linear surface pattern and the second a rotation sensor with a glass slumped groove (using layered glass that is subsequently fired). Other experiments included the embedding of resistance wire to create heat on the surface of the glass depending on where the wire is placed and a matching temperature sensor create by combining copper with the resistive materials itself.
I intend on documenting more thoroughly my experiments and will continue to update my site as and when the work is disseminated.
