Predominantly experimental, Nielsen’s artworks are made in defiance of what is perceived as perfect. Weighty yet spontaneous, his creations carry marks, almost scars, that are inflicted during their making. What may appear rough and unfinished remain as part of the final piece. The intention is to not abuse his glass but to take it to its limits, questioning the role of the artist and how these pieces sit within the world of art and craft.
Neilsen first studied glass at the Orrefors Glass School in Sweden and then went on to the Pilchuch Glass School in Washington and the Royal Institute of Art in Stockholm. He has been the Artist-in-Residence at the Corning Museum of Glass, in the USA, with the museum also acquiring his work for their permanent collections. In 2022, Neilsen was a finalist for the prestigious Loewe Foundation craft prize.
