“I work with glass.

My working life BG (before glass) was bookended by art schools: Edinburgh, where I studied Architecture way back in the last century, and Glasgow School of Art, where I attended an introductory fused glass session at the Summer School in 2015

This really sparked my imagination. Cutting up bits of glass and putting them in the kiln before leaving for the day: each morning was like Christmas.

At the same time I was completing the build of a new extension on my house, a room which, more and more, looked like a potential studio: the kiln arrived in November 2015.

Using the kiln, which heats the glass to up to over 800 degrees celsius, I work with specialist art glass from the USA and also with float (window) glass. The look and feel of the finished piece can vary, depending on how it is fired in the kiln.

Constantly experimenting, I'm interested in seeing how heat, time, temperature, and gravity work on the glass to achieve an end result.

I said I “work” with glass: more accurate to say I “play” with glass.“
