Answer

How much wax do I need for a candle?

Multiply the container’s capacity in fl oz by 0.86 for the fill weight in ounces (GlassNow): an 8 fl oz jar takes about 6.9 oz, or 6.4 oz of wax plus 0.5 oz of fragrance at 8%.

Fill weight (oz) = container capacity to the fill line (fl oz) × 0.86 (GlassNow). An 8 fl oz jar: 6.9 oz, split into 6.4 oz wax + 0.5 oz fragrance at 8%.

Measure to the fill line

Use the capacity up to where the wax will stop, usually about ½ in below the rim, not the brim-full volume printed on some jars. Fill the jar with water to that line and pour it into a measuring cup.
