Making an efficient icebox was not as easy as we might now suppose.In the early nineteenth century,the knowledge of the physics of heat,which was essential to a science of refrigeration,was rudimentary.The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken,for it was the melting of the ice that performed the cooling.Nevertheless,early efforts to economize ice included wrapping up the ice in blankets,which kept the ice from doing its job.
