It is possible to extract silver from silver plated objects. You may wish to do this if the silver on the object is faded or damaged and needs to be replaced, or if you want to replate it with a different type of metal. Whatever the reason, take precautions to ensure your safety while undertaking this process as it can be dangerous.
