Working with Aimer a specialist in Borosilicate glass for the scientific industry, Bethan wanted to celebrate the precision a beauty with in their craft. Focusing on their manual engraving machines which are still in daily use to create the precision lines for measuring vessels. Bethan redesigned the engraving plates replacing volume measurements with pattern rhythm, the rhythms are repeated around the surface of the glass by hand tracing from the plate to a needle that marks the wax coating on the glass. The glasses are then dipped in acid to ethic the design on the surface of the glass.
