Perfume types reflect the concentration of aromatic compounds in a solvent, which in fine fragrance is typically ethanol or a mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The intensity and longevity of a perfume is based on the concentration, intensity, and longevity of the aromatic compounds, or perfume oils, used. As the percentage of aromatic compounds increases, so does the intensity and longevity of the scent. Specific terms are used to describe a fragrance's approximate concentration by the percent of perfume oil in the volume of the final product.
Dr Paolo Rovesti found a terracotta distillation apparatus in the Indus valley together with oil containers made of the same material, carbon dated to 3000 BCE. The report also states that terracotta vessels with plugged orifices of woven materials were used so that when fragrant plant materials were covered with boiling water the vapours impregnated the material, which was subsequently wrung out to isolate the oil.
