Note on weight vs. volume measurements: Many get confused on measurments, because wax has different characteristics than water.
There are 2 measurement ounces: weight ounces, and fluid (volume) ounces.
If you weigh 16 oz of paraffin wax, then melt it, it will take up 20 fluid ounces in a measuring cup. It's still a pound in weight!
16 oz weight paraffin = 20 fluid oz liquid
16 oz weight soy = 18 fluid oz liquid
(Note: GF Soy from SouthernScentations reported to melt to 20 fluid oz)
16 oz weight beeswax = 16 oz liquid beeswax
16 oz weight water = 16 oz liquid water
But test your particular wax just in case it melts differently. Only have to test it once.
It is more accurate to measure your ingredients by weight. But with some experience, you might find, once you know the conversion, that it's actually easier to measure by volume. I do this with my wax, because it's easier for me to hold a pyrex cup under the spout of my presto pot and fill it up to 20 fluid ounces. I know that's a pound (weight) of wax.
The following table shows how much fragrance oil & vybar to use if you are not making up a full pound of wax. For the vybar, this is based on using 1.5 t per pound of wax - you may be using less. Want the math to figure out new batches for yourself? Here it is:
"usual amount" TIMES "new batch size" DIVIDEDBY "usual batch size"
For example, if you use .5t vybar per pound of wax, and you're going to be making 1/2 a pound, the equation would be .5t * 8oz / 16oz. = .25t Once you write it down it's easy to use your calculator :)
An even easier estimate is to just use a 10% ratio. If you measure your wax in ounces, move the decimal point 1 number over to the left to get the ounces needed for FO (14 oz wax uses 1.4 oz FO). Or the other way: .8 oz of FO needs 8 oz of wax (move decimal to the right).

Put a thin layer (about 1/8") of wax in a 1/3 c. metal measuring cup.
Add 1 drop liquid dye and mix in thoroughly.
Stick in the freezer for 10 minutes.
Take wax disk out of the cup, and score and break it into 4 quarters.
Each piece will now be 1/4 drop of color. Store in baggie and mark.
To use, melt it down with your wax or additives, whatever your usual technique is.
