Cutting harder material sometimes requires another technique, like “sawing” for example, but the process on the molecular basis must be similar. The only difference seems to be the smoothness of the surface of the pieces after slicing/cutting. Like, when you use an iron saw to cut.. let’s say a nail… then the nail might look a little frayed… whereas the bread looks smooth after slicing, … Read entire article »
