Candle and Soap Making
Candle Measurements
For many candle makers one of the most
confusing things is measuring ingredients. In this feature I
will try to take some of the mystery out of mixing wax formulas,
and show you where to find on-line converters where applicable.
Formula Basics
The most accurate way to handle any candle making
products is by weight. If you have a product that requires
absolute repeatability, there is no way to avoid buying an
accurate scale. Smaller batches of wax require more accurate
scales since will be using small quantities of most ingredients.
A word of advice here - shop around before buying a scale. When
one of my scales died recently, I planned to buy a replacement
triple beam. Upon looking around the web I found prices varying
as much as 30% - for the same exact scale! After shopping a bit
more, I realized that for a few dollars more I could get a
digital scale which is a big time saver (although I doubt it
will last as long as a triple beam scale).
Percentage Formulas
All percentage formulas add up to 100%. One percent is one
onehundreth or 1/100. A sample percentage formula might look
like this:
93% paraffin
1% Vybar 103
6% scent oil
If we wanted to make 100 pounds of this formula we would use 93
lbs of paraffin, 1 lb Vybar, and 6 lbs of scent. These same
would hold true for 100 ounces or 100 grams.
Percentage formulas are easily scaled up or
down. For example if we needed 10 pounds of this mix we would
divide the 100 pound formula by 10 Giving us 9.3 lbs paraffin,
1/10 lb Vybar, and 6/10 lb of scent. To scale up we would
multiply. For example if we needed 150 pounds of this formula,
multiply all ingredients by 1.5
Summary
Putting this feature together has taken much longer than
planned. Sometimes putting the things you do daily into words is
much more difficult than actually doing them. Next week I will
discuss proportional formulas, "weighing" wax without a scale,
and more. |
