Votives and Melts
We poured our votives and clamshells between 160°F-180ºF (71.1°C-82.2°C). After 24 hours, the wax had minimal shrinkage. A second pour is optional depending on your desired look.
The tart mold and clamshell did have shrinkage through the center, but the edges did not shrink. This made it difficult to top off which caused an uneven finish to the surface. We recommend to not fill these molds all the way so that a second pour can achieve a more level surface.
We did not use mold release, and the votive candle and wick pins came out with a little effort. The votive poured at 180ºF (82.2°C) came out the easiest with just a gentle tap of the wick pin to release. The votives poured below 160ºF (71.1°C) were slightly more difficult to remove but with slight pressure on the wick pin it came out.
The clamshells also un-molded easily.
Because the wax is quite hard, we had some trouble breaking the cubes apart. The tart molds were a little resistant to un-molding. A mold release would be useful.
