That Kristina Riska works on the scale that she does –– her work is massive –– and produces such diaphanous vessels is a testament to extraordinary skill. Critics say her work, “defies gravity” and stretches the boundaries of ceramic sculpture. This footage of the artist at work in her Helsinki studio is quite lovely, and gives us some sense of her process. As beautiful as her curvaceous forms, are her matte, earthy glazes that look like mud, rock, bone and charcoal.
