You confused me at first when you said you made votives with c-3 since c-3 is a container only wax. But I think what you meant is that you poured c-3 into votive size containers??? With my c-3 I heat to 185-190, immediately stir in color and fragrance and pour right away so that the temp doesn’t drop too much. I never add vybar and don’t think you need to either. Vybar is to make the candle more opaque (which soy wax is already very opaque) and to make it harder, which you don’t need to do. I also get a few sink holes but the color always looks great and I hardly get frosting. I do notice wet spots (the wax pulling away) usually a couple days later, but they are not too bad. The candle doesn’t rattle inside the jar. with c-3 it should set up enough in 2-3 days for you to test your burn pool and wick, but if you want to test for fragrance throw you really should wait a full 2 weeks before you burn.
