Traditional Delftware features intricate decoration that requires years of training to achieve — but for his “BLAUW” series, Tim Vanlier threw such painstaking pottery conventions overboard and spent eight months experimenting with new methods to shape, paint and bake. What if you take a tiny detail from a 17th-century plate, enlarge and abstract it, he wondered? Or if you apply waste water instead of paint to create a new color gradient? And what happens when you use a sandblaster to produce special effects? The answers to these explorations, and others, are found in “BLAUW,” a playful collection of porcelain bowls that can be built into a vase, offering a refreshing take on the tradition of stackable tulip vases.
