It takes (about) 7,000,000 flowers to make 1kg of jasmine oil; picked by hand in the early hours when the oil content is at its highest. The reward for such endeavors is an oil densely honeyed and floral but with an animalic note that takes it beyond mere prettiness.
Where lightness and transparency are needed (jasmine oil is far heftier than the flower itself) the synthetic, Hedion, can also be used.
from Italy, France and Morocco
Precious iris concrete is made from the root (not the flowers) of the iris germanica and iris pallida plants. Extremely labour intensive, each root has to be dried for 5 years during which time oxidation develops an aroma that is powdery grey and beautiful to the point of sadness.
Super crisp, clean and dry wood.
