This "Dublin Viking" bowl was inspired by a bowl found in Ireland, brought there by the Vikings a thousand years ago. The original bowls were likely turned on spring-pole or foot treadle lathes and would have had visible grooves from where the hook tools made the cuts.
This is my interpretation of a bowl designed by woodturner Glenn Lucas. It was turned on an electric lathe, sanded and sealed with Walnut oil. Sustainably sourced Butternut wood.
