MUCH easier. Because I'm hopeless at math, I try to work in 10 or 100 increments, and work either in w/w or w/v, eg, 99 GRAMS of oil or alcohol with 1 GRAM of aromatic would be one percent, or 99 MLS of oil or alcohol with 1 ML of aromatic would be the same. Just be consistent with one system or the other in any given blend. I'm ignoring specific gravity in all this, because that math is just too, too much for me.

So 1% of 30 ml is 6-12 drops. I would suggest you just go for the average - 9. Tisserand Quote Link to comment Share on other sites More sharing options...

I would suggest you just go for the average - 9. What I do minimize the variability is use serological pipettes..... Assuming the viscosity of the oil doesn't forbid their use.... With a graduated 1ml pippette, one can measure out their " drop " ...... One can then *make* their " drop " equal 1/20th of a ml..... So......one can measure out 1ml of oil, and then add the diluent to total 100ml... Or .5ml oil, and add diluent to total 50 ml.....or .3 ml, and add diluent to equal 30ml... Working with weight is another way, but I don't have a sensitive enough scale...so I've adopted this " drop " method.... I think technically, the weight method is the more accurate....and if one is using the weight method, one can more or less ignore the specific gravity, because the weight of whatever is the weight.... -- W.

My scale isn't that sensitive. I probably need to upgrade. ~Pixie Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 28, 2006 Report Share Posted September 28, 2006 There has been very interesting reading on this subject. is the most straight forward . The only point I would add if one wanted to be absolutely smack on .... then use your dropper size and work out how many drops per ml......then calculate as suggests, the variable (for you) will have been removed. But whatever way you choose, pippette, drops, weights ..... as long as you don't chop and change your ways your formulas will stay steady. In other words find a method that works for the way you work. mahalo and peace Janitahaan morris --------------------------------- The all-new goes wherever you go - free your email address from your Internet provider.

In > other words find a method that works for the way you work. Janita, ... The dropper method is great for a one-time blend, rather along the lines of an aromatherapy blend, IMO. Dropper size, pressure " squeezing " the bulb, etc., all figure in to take accuracy away in a replicable blend. As most of us move forward with perfume making, which can entail dozens of various aromatics, inlcuding very viscuous ones, highly tinctured ones, etc., the replicability of using the weight measure for blending becomes invaluable and irreplacable.
