The angle grinders are out, the dust is flying and large stones are being turned into unique sculptures.
Ten sculptors taking part in the Ashburton Stone Sculpture Symposium are hammering and chiselling away on projects in Ashburton Domain.
Six artists have started projects with Mt Somers limestone and the rest with Timaru bluestone.
Some artists will complete one work over the course of the symposium, which finishes on November 2, but most will tackle two.
The third biennial symposium has attracted six returning artists, as well as event organiser and Ashburton sculptor Brent Holley.
Newcomers include Australian-based South Korean born Jina Lee.
A number of artists have drawn rough designs on the stones to guide their work and all are working in a fenced area of the domain.
The area has a public footpath and viewing area through it to give the public a closer look and to encourage them to interact with the sculptors.
Brent Holley said all of the stones had been sourced from nearby Mt Somers or further south near Timaru.
The stones were unique and hefty and artists changed ideas and let projects evolve through hammering, cutting and sanding.
Finished works would be transferred and displayed on the Long Lawn (off the West Street car park) in Ashburton Domain until a public auction and family market day on November 11, he said.
Sculptors will attend an evening of artist talks at Ashburton Art Gallery on October 31 from 6.30pm to discuss their works and craft. The event is free and all are welcome.
