Creating your own perfume from dropper bottles:
Methods, mechanics, and mathematics
Cover photo shows supplies and equipment from the book. Far left partially off the page, 32-ounce Boston round bottle that will be used for finished perfume. To the right and behind a 16-ounce Boston round bottle, a 4-cup (1,000 ml) Pyrex® measuring cup. In front of the 16-ounce bottle and measuring cup, dropper bottles with aroma materials. In front of the dropper bottles and behind several 1-ounce perfume bottles, several communion cups being used as mixing pots for trials. Also in the foreground to the left of the notebook, toothpicks used as stirring sticks for the mixing pots and doubling as mini test blotters. Behind the notebook is one of the two electronic balances referred to in this book; an A/C power converter for it appears to the right. In front and to the right are smelling strips (test blotters) used in the development of the fragrance formula. Behind the test blotters are cans of aroma materials and behind them a gallon jug of perfumer's alcohol (SDA 40B, 200 proof).
