Why Are Eggshells So Strong? - Science Connected Magazine
WebApr 18, 2024 · It turns out eggshells are made of both inorganic and organic matter. They contain calcium-containing minerals and abundant proteins. The amazing strength of e ggs comes from a nanostructured mineral associated with osteopontin, a protein also found in composite biological materials such as our bones. In the shell gland (similar to a mammalian uterus), mineralization starts at the mammillae. The shell gland fluid contains very high levels of calcium and bicarbonate ions. The thick calcified layer of the eggshell forms in columns from the mammillae structures, and is known as the palisade layer.
