Q
~ How do I calculate the burn time of a candle? |
A ~ Before
lighting the candle, use a scale to weigh it and find
it's total weight.
Then light and let burn for 3 hours (assuming
it's a 3 inch diameter
candle). Weigh the candle again. Now
you can calculate
the burn rate. For example, if you have a 16
oz candle to begin
with, and after 3 hours of burning it weighs
15.5 oz,
then that means it burned .5 oz in 3 hours. Split that
in 3, so in 1 hour
.16
oz burned away. Now take your original
total weight (16)
and divide that by your per hour burn rate (.16).
This would give
you a total burn time of approximately 100
hours.
Note:
Another guideline to remember is that a standard 2
ounce sized votive
candle mold is rated as a 15 hour votive
mold by the manufacturers.
Divide by 2 and that would mean
that each ounce
should burn for about 7.5 hours. This can vary
and will greatly
depend on your formula, but you can use this
as a goal to aim
for.
