Wax Blend Calculator

Blending a hard wax with a soft one tunes the properties. A kilo at 7:3 is 700 g of A and 300 g of B. Adding 10–30% paraffin or beeswax to a container soy smooths the top and holds fragrance longer, but beeswax raises the melt point, which usually means going up one wick size.

Formula

Wax A = Wax needed × A share ÷ 100, Wax B = Wax needed − Wax A

A blend sits between its two waxes, though values like melt point do not scale in a straight line. Once the ratio is set, pour one candle, cure it two days and burn it — every change of blend needs the wick tested again. Soy and paraffin set at different rates, so the boundary can frost or mottle.

What to enter

InputDefaultAccepted range
Wax needed (g)The wax to melt, by weight.1,0001 and up
A share (%)The percentage that applies to the first item.700 ~ 100

Step by step

FormulaWax A = Wax needed × A share ÷ 100, Wax B = Wax needed − Wax A
With the default numbersWax A = 1,000 × 70 ÷ 100, Wax B = 1,000 − Wax A
AnswerWax A = 700 g

Frequently asked questions

Q. How is Wax Blend Calculator calculated?

Wax A = Wax needed × A share ÷ 100, Wax B = Wax needed − Wax A — Blending a hard wax with a soft one tunes the properties. A kilo at 7:3 is 700 g of A and 300 g of B. Adding 10–30% paraffin or beeswax to a container soy smooths the top and holds fragrance longer, but beeswax raises the melt point, which usually means going up one wick size.

Q. Can you walk through an example?

With Wax needed 1,000g, A share 70%, the answer is Wax A 700g.

Q. What do I need to enter?

Enter Wax needed, A share. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Wax needed (g) moves the answer to Wax needed (g) 500 → Wax A (g) 350 and Wax needed (g) 2,000 → Wax A (g) 1,400. The table below lays out five steps.

Q. How are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

Q. Anything to watch out for?

A blend sits between its two waxes, though values like melt point do not scale in a straight line. Once the ratio is set, pour one candle, cure it two days and burn it — every change of blend needs the wick tested again. Soy and paraffin set at different rates, so the boundary can frost or mottle.
