Analytical pyrolysis with thermally assisted hydrolysis and methylation was employed to investigate ancient ointments collected from Spanish vessels coming from the sixteenth century pharmacies. The ointments were reproduced on the basis of historical recipes and characterization was made in comparison with real samples. Characteristic markers indicate the presence of beeswax, of animal and plant lipids, and of natural resins. Analyses of old samples are consistent with the modern reproductions and with the analysis of raw materials. Multivariate data analysis was used to discriminate between the different types of lipidic materials, also in connection with their relative amount in the samples.

Various natural dye sources have been historically used and are still used today to decorate Pacific barkcloth. The identification of these natural dyes is a challenging task due to their molecular complexity and the scarcity of scientific investigations. In this study, barkcloth samples collected in Tahiti and dyed using local plants, including fruits of Thespesia populnea (L.

Amber glass has been produced since at least the 6th century BC. Its value derives from its ability to mimic natural amber and, later, from its ultraviolet filtering properties. Until the 19th century, amber glass was widely used for the storage of food and medicines because its protective properties had been empirically recognized.

The recreation of historic beverages is possible via contemporary fermentations carried out with microbes revived form the past. Advanced molecular techniques have recently provided opportunities to investigate historic samples, such as those from beer found in shipwrecks, and provide data on their character as well as identifying differences with contemporary products. In some cases, isolates of yeasts and bacteria create the possibility for authentic recreations of fermented beverages that can have cultural and nostalgic interest.
