Final answer:
Jens Quistgaard's ice bucket design for Dansk International features long curves likely influenced by natural forms and mid-century Scandinavian design's focus on organic shapes, functionality, and minimalist elegance.
Step-by-step explanation:
The long curves in the design of Jens Quistgaard's ice bucket made for Dansk International are influenced by his interest and background in the organic forms found in nature and possibly by the seamless integration of form and function that characterizes mid-century Scandinavian design. Quistgaard's use of curves may also be compared to the smooth simple lines of Eero Saarinen's 'Tulip Chair' or the Shaker style staircase that features an organic spiral shape. Given Quistgaard's Scandinavian heritage, it is likely that the organic shapes and simplicity associated with Nordic design, which is known for its minimalism, functionality, and use of natural materials, inspired his creation of the iconic ice bucket. Such influence would be coherent with a broader movement in design that aims to echo natural forms while promoting usability and aesthetic simplicity.
