Revisiting Maya Blue and Designing Hybrid Pigments by Archaeomimetism
arXiv:1007.0818
Abstract
Maya Blue is actually one of the best known examples of an organic-inorganic hybrid material. Yet despite 50 years of sustained interest, its microscopic structure and its relation to durability remain open questions. We address the issue by archaeomimetism: engineering an archaeoinspired pigment, satisfactorily reproducing the colour and chemical stability of Maya Blue. By comparing and contrasting ancient pigment and the new analogue, we deduce a new explanation for this durability.
