It was the colour that initially drew Calgary artist Lauren Chipeur to sulphur. The yellow is so brilliant that in our modern eyes and mind it looks like the product of human imagination. What is sulphur, how is it used? Through ceramics, paper, installation and photography, What on Earth is Holding the Loop Up? looks at the ways in which we can get to know the material reality of the world around us. Lauren slowly peels back the layers, like the layers of an onion.
