For Irish artist and curator Lottie Mac, science and art converge via process. I was floored when I first visited her studio and she explained to me the chemical journey of her steel sheet works, aged outdoors to develop rusted surfaces with delicate imprints of leaves and raindrops. Stunning metal paintings that feel wise with what they’ve witnessed.
“When the steel sheets come,” she explains, “they arrive with this protective layer on them. I take my time scrubbing that off–getting this material that's completely man-made and synthetic, and trying to strip it off as much as I can with soap and water.” She insists on interrupting the interruption, on revealing the natural face of the metal.
“Then after scrubbing off this I leave it outside - for two weeks, three weeks, sometimes two to three months. The different lengths of time allow it to oxidise at different rates. In two weeks, I will get this rich, brighter orange. The longer it's out, the darker and deeper the browning gets and black colouring too. It’s a beautiful process, it makes me step back from work, I have to physically take time from it. In my work with wool and tufting, I’m really manipulating the material. But here, it’s all about loss of control. This really allows me to leave it up to the elements, leave it up to Allah, the higher power. It’s relinquishing control over practice. Sometimes ladybugs crawl over and have even died on them. Sometimes leaves make contact with them, or dew from the grass it's left on. It mimics the topography and landscapes I left it with when it was aging. It’s kind of a broken science” Mac explains, finding divinity in the entropic nature of rust.
