Guest guest Posted September 29, 2008 Report Share Posted September 29, 2008 Do you make your perfume volumetrically or by weight? 60 drops of aromatic material in 15 ml alcohol is volumetric; 300 grams of aromatic material per kilogram of alcohol is by weight. Do you plan to switch to weight-based recipes any time soon? If so, why? If not, why not? _____ It is clear to me that when you get to making perfume in commercial quantities, you have to abandon the volumetric method. (I can just see my recipes now: 1500 drops benzoin. !!!) Also, drops themselves are subject to equivocation; one can't quibble with grams. From wiki.answers.com: " There are 60 metric drops in a 5ml teaspoon. You'll find many variants on this ranging from 50--120, but 60 is a good bet. Generally, drops are not a precise measurement. There are several exact definitions of a " drop " . Here are 3 of them: " --the " metric " drop, 1/20 ml (50 μL), which equates to 60 to a 5ml teaspoon. --the medical drop, 1/12 ml (83⅓ μL). --the Imperial drop, 1/36 of a fluid dram (1/288 of an Imperial fluid ounce or 1/1440 of a gill (approximately 99 μl)).
