I made my first batch of tarts today - just eight of them (about 2 oz. each), since I was trying it out. I used NatureWax V-1 votive blend, and about 1 oz. of Red Velvet Cake FO from Bitter Creek South. On cold sniff, they smell great! But they've got bubbles on top. I heated the wax to about 175 degrees, added color and fragrance, stirred for a couple of minutes (what I thought was enough time to let it blend all together), and poured at about 165 degrees. I've also had problems with bubbles when making votives with this same wax. Any thoughts as to what might be causing it? Other than the bubbles, I think the tarts turned out pretty well, and I'm going to try one out tomorrow to see what the hot throw is like.
