From Monday through Thursday of this week, Sight Unseen is featuring a documentary project by British sculptor Carly Mayer, who indulged her personal curiosity about the factories surrounding her home in Brighton, England, by inviting herself over to photograph their inner workings. For the fourth and final installment, Mayer roams around a small window workshop called Balcombe Glass. ""From an artistic standpoint, I can’t help but find glass beautiful in its most polished and righteous state," she says. "I spent a long time staring at the stock, imagining the pieces as sculptures in their own right. The machinery used to cut the glass fascinated me as well; I expected it to appear menacing and sharp whereas in truth it stood rather friendly, allowing me to photograph its rubber stoppers used to hold the glass firmly in place during production."
