This warming tray TT 20 was designed in 1972 in the sober, technical style of the time and the product range at BRAUN. The actual function, the warming loop, was visibly inserted under the glass as a decorative element. The large version TT 20 also has a particularly warm zone, the circular heat loop in the warming field. A pot can be kept warmer there than the rest of the surface. Otherwise cool minimalism dominates the design of this remarkable object. Restrained, durable, functional and elegant - these are the guidelines for the design of Braun products.
