...Basil Hubbard; Wenxing Kuang; Arvin Moser; Glenn A. Facey; Christian Detellier Abstract Palygorskite-indigo and sepiolite-indigo adducts (2 wt.% indigo) were prepared by crushing the two compounds together in a mortar and heating the resulting mixtures at 150 and 120°C, respectively, for 20 h...

... of a useless, non-bonded surplus. Besides, the blue colour typical of authentic Maya Blue is achieved by using the recommended quantity (≤2 wt%), higher amounts resulting in too much darker hues. On the other hand, clay/indigo adducts loaded with dye amounts exceeding 2 wt% and subjected to anomalously intense...

...) , using surface area measurements and solid-state 13 C CP/MAS-NMR spectroscopy on sepiolite indigo-adducts, stated that their data were incompatible with the hypothesis of a dye incorporation in the clay nano-tunnels. Hence they proposed a new model, in which H-bonds form between indigo C=O/N-H groups...
