The impact of eggshell colour and spot area in Japanese quails: I. eggshell temperature during incubation and hatching results [PDF]
This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica).

TAPHONOMIC EFFECTS OF HIGH TEMPERATURE ON AVIAN EGGSHELL
Abstract The taphonomic effects of heat and or fire on bones, conodonts, and plant tissues have received much attention from paleontologists and geologists, but the effect of high temperatures on amniote eggshell has been unknown.

Taphonomic Effects of pH and Temperature on Extant Avian Dinosaur Eggshell
Abstract Avian and non-avian dinosaur eggshell contains clues that are helpful in the reconstruction of ancient habitats and behaviors. Fossilized eggshell often shows signs of corrosion attributed to acid dissolution of the calcium carbonate, but this process has never been quantified in controlled experiments.

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]
Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.

Eggshell waste is rich source of calcium carbonate and can be applied to protect steel pipe from corrosion. Calcium carbonate precipitation can be naturally formed as a coating to protect steel pipe from oxygen diffusion. However, with calcium carbonate formed due to natural process, it is difficult to achieve the adequate thickness and capable of ...
