Limestone, lime plasters and lime concretes, and how lime's been used in art and architecture - that's what Dunedin artist Tim Barlow is exploring in his new project The Lime Burners. Tim received the 2021 Environment Envoy commission to create the work that will be housed in the city's old Gasworks. Tim Barlow' talks with Lynn Freeman about his fascination with Lime. His plans for the project involve other artists too - including Louisa Baillie who joins the conversation. The Lime Burners opens on May 14 at the Gasworks Museum in Dunedin. There are planned to be workshops too. Environment Envoy is funded by Dunedin Dream Brokerage and Dunedin City Council
