MEET THE TUTORS
We are Kelvin and Katrin.
We are K².
As the founding directors and course leaders of K2 both Katrin Spranger and Kelvin J. Birk have an impressive repertoire of expertise to draw upon. Having trained extensively in traditional jewellery and silversmithing techniques at top institutions in Germany, Sweden and the UK, they now run successful jewellery businesses. Between them they have 20+ years experience teaching and lecturing in the field of jewellery, design and business planning both in the UK and abroad.
They overlap in their creative outputs and their love of making, but their practices and journeys deviate greatly. It’s part of what makes the K2 Jewellery School the perfect balance of creative energy, practical techniques and business savvy, creating an environment that allows for exploration across the expanse of possibilities that jewellery making can offer.
Katrin Spranger
Katrin Spranger trained and studied in Germany and holds a Masters degree in Jewellery from the Konstfack University College of Arts, Crafts and Design in Sweden. Working as a conceptual jewellery artist, she creates stories that comment on consumer culture, environment and science fiction. Focusing on resources that might become depleted in the future, she explores natural materials including crude oil, water and honey to develop jewellery that is wearable yet ephemeral and interactive.. Her hybrid practice touches upon several disciplines like fashion, food, photography, performance and installation.
Katrin has taught widely both in London and Germany. She has won numerous awards and has exhibited throughout Europe and North America
Kelvin Birk
Kelvin J. Birk studied jewellery making in Germany and holds a Masters degree with distinction in Silversmithing, Jewellery and Allied Arts from the Sir John Cass Faculty of Art. He has exhibited at major exhibitions both in the UK and abroad.
He creates one-off bespoke pieces in silver, gold and crushed gemstones. Within his work, he consciously disregards what is traditionally considered precious, revelling in the lack of control, allowing chaos to take over and the nature of the precious materials to dictate the outcome of the pieces.
Kelvin has taught extensively, running jewellery master classes and workshops internationally. He has tutored at Kensington & Chelsea College, London. He has also worked as a visiting lecturer on the Fashion Masters course at the University of Westminster London as well as at Kunstschule in Liechtenstein. He is currently a part-time lecturer on the BA Jewellery & Silversmithing course at Metropolitan University London.
