Hannah Gibson has held a passion for glass since childhood and is now a multi-award winning glass artist. In this episode, she talks about how her upbringing inspired her love for the material and for geology, how she has studied and practised many of the techniques for making glass and artworks from it, how sustainability is her other passion and how she casts from recycled glass using her geological background to analyse it, where she sources her glass, how she likes to share her passion with the public and some of the extraordinary reactions she receives as a result.
