Quartz is a tactile and luminous work by Anna Betbeze, created through the application of acid dyes, watercolour, and ash on wool. The interplay of materials produces a richly textured surface where translucent washes of color merge with the raw, carbonized residue of ash, evoking the geological formations suggested by the title. The work reflects Betbeze's ongoing exploration of process and material transformation, inviting viewers to contemplate the passage of time embedded within the fabric itself.
