Storing and Using
The rhizomes (Root) should be stored well, protecting it against fungus and insect attack for three years. The fresh rhizomes are almost odorless.
The distilled oil solidifies in the receiver as a wax-like and cream colored mass known as Orris Concrete. It is solid because of the high content present of myristic acid, a white sterin like substance.
Orris Concrete melts when it reaches around body temperature. It and has a woody, fatty-oily, yet distinctly violet-like odor: sweet floral, warm & tenacious with a fruity undertone. Orris Concrete is used in perfumery (as such) when the presence of myristic acid is not prohibitive, e.g.: in soap perfumes where the weak acid only acts as a fixative. Also note, the methyl and ethyl esteres of myristic acid are often used for blending in violet type perfume bases. Because of the high costs involved in producing Orris concrete it limits its application to a certain degree. Yet even small amounts of this exquisite material lends to very fine effects in various perfume types other than the old fashioned violet.

Famous quotes containing the word storing:
“Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.”
—Jeremy Campbell (b. 1931)
