Woll patent pending German engineered technology is more than just diamonds, it is the process. We combine real larger diamonds with advanced Robotics in a multi-layer process. The difference is not just in the cooking surface, but also in the German manufacturing technology of an improved cast Molding process, versus the more traditional method of pressure casting. Woll State of the art process eliminates the need for oily silicon materials used to release the pans from its mold. These materials are the fundamental reason for imperfections in the final Product, such as bubbles and reducing a pans heat conducting ability. This brings Woll one step closer to creating the perfect pan. Use Woll silicone splatter guards to protect your kitchen and stove. It is made of high quality, food safe silicone and is dual functional as a splatter guard and a trivet. The splatter guard is oven safe up to 500 Degree, dishwasher safe and available in two sizes, 11″ square and 11″ round diameter.
