Web12 de abr. de 2024 · At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge. When you consider that most household razor blades are 300 to 600 angstroms, obsidian can still cut it with the sharpest materials nanotechnology can produce. WebMercury in thermometers can cause gold to break: This might seem a bit random, but since we’re on the subject of things that can cause gold to become brittle, I might as well mention that exposure to liquid mercury, such as the type of mercury contained in old fashioned thermometers, will cause gold to become brittle and break.
