Can you use container soy wax for clamshells?

[AudraT]

Hello all. I know this question has been asked before but it was asked about 12 years ago so I am wondering what new developments have been made in the industry. I currently use American Soy Organics Freedom Soy Wax and ProBlend 600 paraffin/soy from The Flaming Candle. I was thinking of adding clamshells to my shop but I see they recommend waxes specifically made for clamshells/tarts or using pillar waxes. Personally, I would love to just use the two waxes I have now. Does anybody use the softer soy waxes or paraffin/soy waxes for clamshells and what has been your experience? Do you add something to your wax to harden it? If you are using harder waxes, what do you recommend?

The main issue with container waxes for clams/melts is they are designed to not pull away from the sides of the containers (wet spots). To come out of the clams they will need to “let go”, or shrink a bit.

 

you could try adding some stearic acid to help with the shrink, or something similar.  Additives will mess with your appearances, though, so prepare for some testing.

 

you could try to chill them after they are set up to see if they release, or perhaps a silicone spray in the clams to prevent the seal if you will. 
 

in any event, I’d try to use what you have in a little experiment before testing additives. your wax may turn out ok. Only one way to find out.

I have always used the same wax for container candles and clamshells. Currently I am using ASO millenium. I used to use 464. Never been a problem with release, but it never gets very hot here, so the wax does not get too soft.  Dunno if that makes a difference...
