Changing the vessel or wax on a candle recipe
Swap a recipe's vessel, wax, or fragrance — see what recalculates and what doesn't — before you commit to the change.
You can point an existing candle recipe at a different vessel, a different wax, or a different fragrance. On a candle recipe, some swaps just relabel it; others recompute the numbers that make it burn right — so it's worth knowing which is which before you save.
Changing the vessel
Swap in a different vessel and Hi Ellie rescales the wax weight — recomputed from the new vessel's fill volume and the wax's density, so the pour fills the jar the way it's meant to instead of falling short or running over the rim.
Heads up: the rescale needs a fill volume set on the new vessel. If it's missing, add it in the candle pantry first.
Changing the wax
Swap in a different wax and the same rescale runs — this time it's the new wax's density, against the vessel volume you're already using, that sets the new weight. A wax swap usually comes with a different melt point and pour temperature too, so give the recipe's steps a look afterward: the amount will be right, but the temperatures may need adjusting.
Changing a fragrance
Swapping a fragrance is a scent decision, not a geometry one — it does not trigger a rescale. The fragrance load stays exactly where you set it, as a percentage of the wax weight; only the character of the scent changes.
Heads up: a new fragrance carries its own flash point and supplier max load. Re-check both against your recipe's pour temperature and load percentage — see the candle pantry for where those numbers live.
When to swap vs. remake
Swapping is for the recipe you already have, redirected at a new jar, a different wax, or a different scent. If you're changing more than one of the three at once — or the result barely resembles what you started with — reach for the candle wizard instead. It builds the whole recipe around the new combination rather than patching it piece by piece.
