need help please..

Capt Dan, here's a good reason why a scale, even a sorta crappy one is better than trying to calculate out weight to volume for candlemaking.

BTW, you'll need the specific gravity of the fo. And, every fo has it's own sp. gravity. Also, the same type of fo, (ex. Cucumber Melon) from company A may have a different calculation than company B. This measurement should be in a MSDS. I looked up a few fo's and here, for simplicity, I'll use 9lbs/gal.

To find how many teaspoons are in one fluid oz....

9 lbs/1 gal * 1 gal/768 tsp * 16 oz/1 lb = 144 oz/768 tsp = 0.1875 oz/tsp

[Note: Here, we should do a decimal place adjustment, but we'll just leave it for now... ]

To calculate 8% fo for 10 oz. candle....

0.08 * 10 oz. = 0.8 oz.

A ballparked tsp. amount....

0.8 oz/ (0.1875 oz/tsp) = 4.26... tsp. = roughly, just over 4 tsp.

In measuring those tsp's in a teaspoon, you'll have to watch for overfilling & surface tension. Or, you'll end up with mo' fo anyhow. Anyway you stack them cookies, it's just not precision measurement!

It's past my bedtime,

HTH in some way... :wink2:

Forgot to add...

If you vary the tsp. amt by just a bit, it'll quickly change the fo %.

Ex.

4 tsp = ~ 0.74(ish) %

4.5 tsp = ~ 0.84(ish) %

etc.

Well, I'm tired so I hope I got those calc's correct. But the point was to emphasize how troublesome this method would be! :smiley2:

(Adding the following to the post so it won't bump.)

A specific gravity comparison on a particular supplier's website lists the specific gravity of two different fo's:

fo A = 7.35 lbs/gal

fo B = 9.41 lbs/gal

Calc'd out, this would be some approx. tsp's for 0.5 oz of fo:

A = 3.2 tsp

B = 2.5 tsp (0.7 tsp difference between the two!)

Just adding this to show the difference in vol. for a specific weight. :wink2:
