Release and shrink

By Dwight Davis, Founder

Updated

On this page8
Unlike a candle, this product has to leave its container, and the container was not designed for that.

The difference from a candle

A candle burns in its vessel and never has to release. A melt is extracted by a customer with their fingers, so the geometry that makes a good candle jar makes a bad melt cup, and nothing in the product description tells you which you are buying.

Straight walls hold on

A straight-sided jar grips the wax along its whole height. A tub with a taper releases far more easily, which is why the PP round tubs on this shelf are worth more attention than their appearance suggests.

Shrinkage is your friend here

Wax contracts as it cools and pulls away from the wall, which is a defect in a candle and a feature in a melt. Cooling slowly and evenly gives a cleaner pull-away than chilling, and chilling can crack the surface.

Wide mouths make it possible

The dominant necks here are 89-400 and 70-400, 56 containers each, which is a genuinely wide opening. A narrow neck turns extraction into a problem no amount of release helps with.

Fill height changes the grip

A shallow fill in a tall jar is harder to reach and easier to break up in the attempt. Matching the fill to a shallow container rather than part-filling a deep one is usually the better answer, and it also makes the jar look full.

Test it cold, by hand

Set, capped, left overnight and then opened and emptied the way a customer would. If it takes a knife, the container is wrong, and that is a decision to make before the case arrives rather than after.

Candle jar or melt cup is the real question

Nothing in a listing distinguishes them, because the distinction is in what you are going to do with it. Asking whether the contents have to come back out is the question that sorts this shelf correctly.
