KITCHEN The reflective surfaces of these kitchen tools mimic the glass and metallic exteriors of metropolitan buildings, uniting the aesthetics of the Machine Age with the art of cooking. Single-purpose appliances with electric motors replaced the labor of toasting, chopping, squeezing, and blending previously completed by household help in wealthy homes. Encased in stylish chrome-plated designs, these objects reflect a conceptual shift for kitchens from a workshop for preparing food to a culinary laboratory, engineered for efficiency.
